How many subtests does the CTEL have?

Three. CTEL 1 (Language and Language Development, test 031), CTEL 2 (Assessment and Instruction, test 032), and CTEL 3 (Culture and Inclusion, test 033). Each subtest is scored and passed separately, so you can prepare for and pass CTEL 1 on its own and bank that passing score.

What two domains does CTEL 1 cover?

Domain 1, Language Structure and Use, covers linguistics: phonology and morphology, syntax and semantics, language functions and variation, discourse, and pragmatics. Domain 2, First- and Second-Language Development, covers theories, processes, and stages of first- and second-language acquisition (Krashen, Cummins, Selinker, Chomsky, Vygotsky) and the cognitive, affective, sociocultural, and political factors that affect it. The 50 multiple-choice items split evenly, 25 per domain.

What is a passing score on CTEL 1?

You need a scaled score of 220 on CTEL 1. The multiple-choice and constructed-response portions are combined into that single scaled score, with multiple choice weighted about 70% and the written assignment about 30%. Each subtest is passed independently at 220.

What is the difference between BICS and CALP?

BICS (basic interpersonal communicative skills) is everyday conversational language that develops in roughly 1–3 years; CALP (cognitive academic language proficiency) is the academic language of school that takes about 5–7 years. Cummins's distinction matters because a learner can sound fluent in conversation yet still struggle with grade-level academic work — CTEL 1 tests this gap.

Who needs to pass CTEL 1?

Candidates pursuing a California English Learner authorization (such as a CLAD or bilingual authorization) by examination take the CTEL. Passing all three CTEL subtests, including CTEL 1, is one route to the authorization that lets a teacher provide instruction to English learners. This guide, practice test, and flashcards are free.

How should I use this CTEL 1 study guide?

Work one domain at a time. Read each module, take the end-of-module checkpoint quiz, then drill weak areas with our free practice test and flashcards. Lock down the linguistic levels (phonology through pragmatics) and the SLA theorists (Krashen, Cummins, Selinker, Chomsky, Vygotsky), and rehearse the constructed-response essay. Check off each section to raise your exam-readiness score.

Do these materials match the current CTEL 1?

Yes. This guide is organized to the current CTEL Subtest I (031) structure from the California Commission on Teacher Credentialing and Pearson — its two domains of Language Structure and Use and First- and Second-Language Development — and aligns to the California ELD Standards from the California Department of Education.

What is a phoneme, and how is it different from a phone?

A phoneme is the smallest unit of sound that distinguishes meaning in a language — swapping /p/ for /b/ turns 'pat' into 'bat,' so /p/ and /b/ are separate phonemes in English. A phone is any physical speech sound; allophones are predictable variants of one phoneme, like aspirated and unaspirated [p]. Phonology is a Domain 1 (Language Structure and Use) topic on CTEL 1. A minimal pair — two words differing in one sound — proves two sounds are contrasting phonemes.

What is a morpheme, and how do free and bound morphemes differ?

A morpheme is the smallest unit of meaning. A free morpheme stands alone as a word — 'dog,' 'happy.' A bound morpheme must attach to another — prefixes and suffixes like 'un-' or '-ness.' 'Unhappiness' has three morphemes: un- + happy + -ness. Morphology is a Domain 1 topic on CTEL 1. Bound affixes are inflectional (mark grammar, e.g., plural -s) or derivational (build a new word, e.g., -ness).

What is the difference between inflectional and derivational morphemes?

An inflectional morpheme marks a grammatical feature without changing the word's part of speech — plural '-s' (dog → dogs), past '-ed,' comparative '-er.' English has only eight. A derivational morpheme creates a new word, often a new part of speech — '-ly' (quick → quickly), 'un-' (happy → unhappy). Word formation is part of morphology in Domain 1 of CTEL 1. Inflections never change the part of speech; derivations frequently do.

What does syntax study, and how does it differ from semantics?

Syntax is the set of rules for arranging words into grammatical phrases and sentences — word order, agreement, and structure. Semantics is the study of meaning. A sentence can be syntactically correct yet semantically odd ('Colorless green ideas sleep furiously'), showing the two systems are distinct. Syntax and semantics are both Domain 1 (Language Structure and Use) topics on CTEL 1. Surface structure is the spoken/written order; meaning relationships can differ from that surface order.

What is pragmatics, and how does it differ from semantics?

Pragmatics is how meaning depends on context, speaker intent, and social rules — what an utterance does, not just what it literally says. 'Can you pass the salt?' is literally a yes/no question (semantics) but functions as a polite request (pragmatics). It covers speech acts, politeness, and turn-taking. Pragmatics is a Domain 1 topic on CTEL 1 and overlaps discourse. Sociolinguistic competence — knowing what is appropriate to whom, when — is part of pragmatic ability.

What is discourse, and what makes a text cohesive and coherent?

Discourse is language above the sentence — how utterances connect into conversation and text. Cohesion is the surface glue: pronouns, conjunctions, and transitions that tie sentences together. Coherence is the underlying logical flow that makes the whole make sense. Both are needed for effective spoken and written discourse. Discourse is a Domain 1 topic on CTEL 1, closely tied to pragmatics. Turn-taking, topic management, and register shifts are features of spoken discourse.

What is language variation, and what are dialects and registers?

Language varies by region, social group, and situation. A dialect is a rule-governed variety of a language tied to a region or group — not a deficient or 'incorrect' form. Register is the level of formality chosen for a situation. Sociolinguistics studies how factors like setting, audience, and identity shape these choices. Language functions, variation, and sociolinguistics are Domain 1 topics on CTEL 1. Every dialect is systematic; valuing a learner's home language and dialect supports identity and learning.

What is comprehensible input, and what does Krashen mean by 'i + 1'?

Comprehensible input is language a learner can understand even though it is slightly beyond their current level — Krashen's 'i + 1.' Acquisition happens when input is made understandable through context, visuals, and modeling. The teacher's job is to keep input just above the learner's level and clear enough to follow. Krashen's Input Hypothesis is a core Domain 2 (Language Development) topic on CTEL 1. Make input comprehensible with realia, gestures, slower speech, and connections to prior knowledge.

What is the affective filter, and how does a teacher lower it?

The affective filter is Krashen's metaphor for an emotional barrier — anxiety, low motivation, or low self-confidence — that blocks comprehensible input from being acquired. A welcoming, low-anxiety classroom that values the home language and reduces pressure to perform 'lowers the filter' so input can get through. The Affective Filter Hypothesis is a Domain 2 topic on CTEL 1. Affective factors (motivation, anxiety, attitude) are explicitly part of the factors that affect language development.

What is the difference between BICS and CALP (Cummins)?

BICS — basic interpersonal communicative skills — is everyday conversational language that develops in about 1–3 years. CALP — cognitive academic language proficiency — is the decontextualized academic language of school, taking roughly 5–7 years. A learner can sound fluent in conversation yet still struggle with grade-level academic work. Cummins's BICS/CALP distinction is a high-yield Domain 2 topic on CTEL 1. Never assume conversational fluency means a learner is ready for academic tasks — CALP is still developing.

What is interlanguage, and why does fossilization happen?

Interlanguage, a term from Larry Selinker, is the evolving, rule-governed in-between language system a learner builds on the way to the target language — it contains features of the first and second languages. Fossilization is when certain non-target-like forms become permanent and stop changing despite continued exposure. Selinker's interlanguage and fossilization are Domain 2 (second-language development) topics on CTEL 1. Learner errors are often systematic evidence of an evolving interlanguage, not random mistakes.

What is Chomsky's Universal Grammar and the innatist view of acquisition?

Chomsky's innatist (nativist) theory holds that humans are born with a Universal Grammar — an inborn capacity for language — and a 'language acquisition device.' Children construct a complex grammar from limited, imperfect input, far beyond what imitation alone could explain. This contrasts with the behaviorist view that language is learned by reinforcement. Theories of first-language acquisition are a Domain 2 topic on CTEL 1. Behaviorist (Skinner), innatist (Chomsky), and interactionist (Vygotsky) theories each explain part of the picture.

How does Vygotsky's zone of proximal development apply to language learners?

Vygotsky's zone of proximal development (ZPD) is the gap between what a learner can do alone and what they can do with guidance from a more capable other. Language develops through meaningful social interaction within this zone, and scaffolding — temporary, targeted support that is gradually removed — is the practical way to teach inside it. Vygotsky's sociocultural theory and the ZPD are Domain 2 topics on CTEL 1. Scaffolds — sentence frames, modeling, graphic organizers — operationalize the ZPD in the classroom.

What are the stages of second-language acquisition?

Learners pass through predictable stages: pre-production (a silent/receptive period with nonverbal responses), early production (one- to two-word answers), speech emergence (simple sentences with errors), intermediate fluency (more complex, connected language), and advanced fluency (near-native social and academic proficiency reached over years). Stages and processes of language acquisition are a Domain 2 topic on CTEL 1. Match instruction to the stage — accept nonverbal responses early, then build toward academic discourse.

The smallest unit of sound that distinguishes meaning — /p/ and /b/ are separate phonemes because they distinguish 'pat' from 'bat.'

The study of how a language organizes and combines its sounds, including the rules that govern which sounds can occur together.

The study of the physical production (articulation) and acoustic properties of speech sounds, independent of meaning.

A predictable variant of a phoneme that doesn't change meaning — the aspirated [pʰ] in 'pin' and unaspirated [p] in 'spin' are allophones of /p/.

Two words that differ in exactly one sound and have different meanings (pat/bat), proving the two sounds are contrasting phonemes.

The smallest unit of meaning in a language — 'un-', 'happy', and '-ness' are each a morpheme.

A morpheme that can stand alone as a word, such as 'dog,' 'happy,' or 'run.'

A morpheme that must attach to another, such as the prefix 'un-' or the suffix '-ness.'

Inflectional morpheme

A bound morpheme that marks a grammatical feature without changing the part of speech, like plural '-s' or past '-ed.'

The study of meaning in language — the meaning of words and sentences, including denotation, connotation, and relationships among meanings.

How meaning depends on context, speaker intent, and social rules — what an utterance does, not just what it literally says.

A pragmatic function performed by an utterance, such as requesting, promising, or apologizing.

A rule-governed variety of a language tied to a region or social group — systematic, not 'incorrect.'

The level of formality and style chosen to fit a situation, audience, and purpose.

The study of how social factors — region, class, identity, setting — shape language use and variation.

Language a learner can understand though it is slightly beyond their current level (Krashen's i + 1), made clear through context and support.

A mental barrier raised by anxiety, low motivation, or low confidence that blocks comprehensible input from being acquired.

Acquisition vs. learning

Krashen's distinction: acquisition is subconscious (like a first language), learning is conscious rule-study; acquisition drives fluency.

An early stage in which a learner understands more than they produce — listening and comprehending while speaking little.

Basic interpersonal communicative skills — everyday conversational language; develops in roughly 1–3 years (Cummins).

Cognitive academic language proficiency — the decontextualized academic language of school; develops over roughly 5–7 years (Cummins).

Common underlying proficiency

Cummins's idea that a bilingual's two languages share a cognitive base, so skills and concepts transfer from L1 to L2.

Selinker's term for a learner's evolving, rule-governed in-between language system on the way to the target language.

When certain non-target-like forms in a learner's interlanguage become permanent despite continued exposure.

Chomsky's proposed inborn capacity for language that lets children construct a grammar from limited input.

The two domains split the multiple-choice section evenly, 25 / 25, and the single constructed-response essay draws on Domain 2 — so weight your study across both. The CTC organizes the subtest into these two domains; this guide teaches each as a module, in official order, with its core topics as checkable subsections.^[2]

Module 1 · Language Structure & Use

Language as a system — the levels of linguistic analysis from sound to meaning in context. This domain asks you to identify which level of language a phenomenon belongs to and to analyze how the English language is built.^[2] Work from the smallest unit upward.

The layers of the language system — from the smallest sound to meaning in context

1
Phonology · Sounds
How sounds (phonemes) are organized and combined — e.g., /p/ vs. /b/ distinguishes 'pat' from 'bat'.
2
Morphology · Word parts
How morphemes (the smallest meaningful units) build words — 'un-', 'happy', '-ness'.
3
Syntax · Sentences
The rules for arranging words into grammatical phrases and sentences.
4
Semantics · Meaning
The literal meaning of words and sentences — denotation, connotation, and relationships among meanings.
5
Pragmatics · Use in context
How meaning depends on context, speaker intent, and social rules — what a sentence does, not just what it says.

Discourse sits above the sentence — how utterances connect into coherent conversation and text — and overlaps pragmatics. CTEL 1 expects you to name the level a given phenomenon belongs to.

1.1 Phonology & Phonetics

studies how speech sounds are physically produced and heard; studies how a language organizes those sounds into a system. The key unit is the — the smallest sound that distinguishes meaning.

A like pat/bat proves /p/ and /b/ contrast. An is a predictable variant that doesn’t change meaning, like the aspirated and unaspirated [p]. Voicing, place, and manner of articulation distinguish consonants.

Core phonology concepts on CTEL 1
Term	What it is	Example
Phoneme	Smallest sound that distinguishes meaning	/p/ vs. /b/ in pat / bat
Allophone	Predictable variant of a phoneme	Aspirated [pʰ] in 'pin' vs. [p] in 'spin'
Minimal pair	Two words differing in one sound	pat / bat, sip / zip
Voicing	Whether the vocal cords vibrate	/b/ (voiced) vs. /p/ (voiceless)
Suprasegmentals	Stress, rhythm, intonation	Prosody over and above individual sounds

1.2 Morphology

Morphology is how words are built from — the smallest units of meaning. A stands alone (dog); a must attach (un-, -ness). Bound affixes are (mark grammar, never change the part of speech — plural -s) or (build a new word, often a new part of speech — -ly). Unhappiness is three morphemes: un- + happy + -ness.

Types of morphemes — free vs. bound, inflectional vs. derivational

Morpheme — the smallest unit of meaning

Free morpheme

Stands alone as a word: dog, happy, run, book.

Bound morpheme

Must attach to another morpheme — a prefix or suffix: un-, -ness, -s, -ed.

Bound affixes split into two kinds:

Inflectional

Marks grammar without changing the part of speech: plural -s (dog → dogs), past -ed, comparative -er. English has only eight.

Derivational

Builds a new word, often a new part of speech: -ly (quick → quickly), un- (happy → unhappy), -ness (happy → happiness).

Unhappiness = un- (derivational) + happy (free) + -ness (derivational): three morphemes.

1.3 Syntax

is the system of rules for combining words into grammatical phrases and sentences — word order, agreement, and hierarchical structure. English is largely a subject–verb–object language, and parts of speech, phrase structure, and sentence types (declarative, interrogative, imperative) all fall here. A sentence can be grammatical (well-formed syntax) yet meaningless, which shows syntax is separate from .

1.4 Semantics

is the study of meaning — of words and of sentences. Know denotation (literal meaning) versus connotation(associated meaning), and the relationships among word meanings: synonyms, antonyms, homonyms, polysemy, hyponymy, and idioms whose meaning isn’t the sum of their parts. Semantic transparency and figurative language are frequent sources of difficulty for English learners.

Semantic relationships to know
Relationship	Meaning	Example
Synonym	Words with similar meaning	big / large
Antonym	Words with opposite meaning	hot / cold
Homonym / homophone	Same form or sound, different meaning	bank (river / money); to / too / two
Polysemy	One word, multiple related senses	'head' of a person, a table, a company
Idiom	Meaning isn't the sum of the parts	'kick the bucket' = die

1.5 Pragmatics & Discourse

is meaning in context — what an utterance does. “Can you pass the salt?” is literally a question but functions as a polite request: that is a . Pragmatics covers politeness, implicature, and appropriateness.

is language above the sentence — how utterances connect into coherent conversation and text through cohesion (surface links) and coherence (logical flow), plus turn-taking and topic management.

1.6 Language Variation & Sociolinguistics

Languages vary by region, group, and situation. A is a systematic, rule-governed variety — never a deficient form of the language. is the formality chosen to fit an audience and purpose.

studies how setting, identity, and social factors shape language use, including code-switchingand language functions (the purposes language serves). For teaching, this means valuing a learner’s home language and dialect as assets.

Checkpoint · Language Structure & Use

Question 1 of 10

What is a phoneme?

Module 2 · First- & Second-Language Development

How first and second languages are acquired — the major theorists and the factors that speed or slow development. This domain expects you to know the researchers and, more importantly, to apply their ideas to classroom situations.^[2] The single constructed-response essay draws from this domain.

Theories of language acquisition — behaviorist, innatist, interactionist

Behaviorist

Skinner

Language is learned through imitation, habit formation, and reinforcement of correct responses. Explains some vocabulary and routines but not novel, creative sentences.

Innatist / Nativist

Chomsky

Humans are born with a Universal Grammar and a language acquisition device; children construct grammar from limited input, far beyond what imitation could supply.

Interactionist / Sociocultural

Vygotsky · Long

Language develops through meaningful social interaction. Vygotsky's zone of proximal development and scaffolded, negotiated input bridge what a learner can do alone and with help.

CTEL 1 expects you to attach each idea to its theorist and recognize that today’s teaching blends the innatist and interactionist views.

2.1 Theories of Language Acquisition

Three broad theories explain how language develops. The behaviorist view (Skinner) says language is learned by imitation and reinforcement.

The innatist view (Chomsky) posits an inborn and a language acquisition device that lets children build complex grammar from limited input.

The interactionist / sociocultural view (Vygotsky, Long) stresses meaningful social interaction and negotiated, comprehensible input. Modern practice blends the innatist and interactionist views.

2.2 Krashen, Cummins, Selinker & Vygotsky

Four theorists anchor this domain. Krashen’s five hypotheses — especially (i + 1) and the — explain how acquisition happens. Cummins gives the / distinction and , the reason skills transfer from the first language. Selinker describes and . Vygotsky’s grounds .

Krashen’s five SLA hypotheses (high-yield on CTEL 1)

Acquisition–Learning

Acquisition is subconscious (like a child's first language); learning is conscious rule-study. Acquisition drives fluency.

Natural Order

Grammatical features are acquired in a predictable order that explicit teaching cannot fully change.

Monitor

Consciously learned rules act only as an editor (a 'monitor') on output — they don't generate fluent speech.

Input (i + 1)

Acquisition happens when learners understand input slightly beyond their current level, made comprehensible by context.

Affective Filter

Anxiety, low motivation, or low confidence raise a 'filter' that blocks input. A low-anxiety class lowers it.

The two most-tested: comprehensible input (i + 1) and the affective filter.

BICS vs. CALP (Cummins) — why “sounds fluent” isn’t the whole story

BICSCALP

What it isBasic interpersonal communicative skills — everyday, conversational languageCognitive academic language proficiency — the academic language of school

ContextContext-embedded (gestures, real objects, shared situation carry meaning)Context-reduced / decontextualized (meaning carried by words alone)

Cognitive demandCognitively undemanding (playground talk, ordering food)Cognitively demanding (analyzing a text, writing an argument)

Time to developRoughly 1–3 yearsRoughly 5–7 years (or more)

Classroom riskA student sounds fluent in conversation……yet still struggles with grade-level academic tasks

The exam tests this gap: never assume conversational fluency means a learner is ready for grade-level academic work.

2.3 Stages of Acquisition

Second-language learners pass through predictable stages: , early production, speech emergence, intermediate fluency, and advanced fluency. The pace varies, but the order is consistent. The teaching implication is to match expectations to the stage — accept nonverbal responses early and build toward connected academic discourse.

Stages of second-language acquisition — silent period to fluency

1
1 · Pre-production (Silent / Receptive)
Minimal speech; the learner listens, builds receptive vocabulary, and may respond nonverbally (point, gesture, draw). The 'silent period.'
2
2 · Early Production
One- and two-word responses and short phrases; vocabulary of roughly 1,000 words. Answers yes/no and either/or questions.
3
3 · Speech Emergence
Simple sentences and longer phrases with grammar and pronunciation errors; begins to ask and answer simple questions and read short texts.
4
4 · Intermediate Fluency
More complex sentences and connected discourse; growing academic vocabulary; can express opinions and think in the second language.
5
5 · Advanced Fluency
Near-native fluency in social and academic contexts (CALP). Reached over years, not months; needs continued academic-language support.

Match instruction to the stage: accept nonverbal responses early, then build toward connected academic discourse. The stages are predictable, but their pace varies by learner.

2.4 Factors Affecting Acquisition

CTEL 1 groups the factors that affect language development into four kinds. Cognitive/linguistic factors include age, prior literacy, and (positive and negative).

Affective factors are motivation, anxiety, attitude, and self-confidence (the ). Sociocultural factors include identity, community, and the status of the home language.

Political factors include language policy, program availability, and societal attitudes toward bilingualism.

Factors affecting language development
Type	Examples	Classroom implication
Cognitive / linguistic	Age, prior literacy, L1 transfer	Leverage L1 literacy; expect systematic transfer errors
Affective	Motivation, anxiety, attitude, confidence	Build a low-anxiety, welcoming class to lower the filter
Sociocultural	Identity, community, home-language status	Value the home language and culture as assets
Political	Language policy, programs, societal attitudes	Recognize how policy shapes access and bilingual support

2.5 Implications for Instruction

Theory points toward practice. Make input comprehensible, lower the affective filter, build academic language (CALP) deliberately, use within the , and treat the home language and developing interlanguage as assets rather than deficits.

Errors are evidence of a learning system at work, not failure. These principles are exactly what the constructed-response essay rewards.

Checkpoint · First- & Second-Language Development

Question 1 of 10

According to Krashen's Input Hypothesis, language is acquired most effectively when learners are exposed to input that is:

The Constructed-Response Assignment

CTEL 1 includes one constructed-response (essay) assignment, worth about 30%of your scaled score, drawn from Domain 2. It typically presents a classroom scenario or a focused prompt about first- or second-language development and asks you to apply principles — for example, to explain a learner’s behavior using acquisition theory and recommend an instructional response. Scorers reward an accurate, well-supported, on-topic response that uses the field’s concepts correctly.^[3]

How to structure a strong CTEL 1 written response

1
Read the prompt and identify the task
Pin down exactly what is asked — identify a concept, explain a cause, and/or recommend a strategy. Address every part.
2
Name the concept and the theorist
State the relevant principle precisely (e.g., comprehensible input, BICS vs. CALP, the silent period) and attribute it (Krashen, Cummins) to show command of the field.
3
Tie the concept to the scenario's evidence
Quote or reference specific details from the scenario and explain how the principle accounts for them — don't define in a vacuum.
4
Recommend and justify a response
Propose a concrete instructional move and explain why it fits, connecting it back to the theory and the learner's needs.

How to Use This CTEL 1 Study Guide

Because each CTEL subtest is passed separately, you can focus entirely on CTEL 1. Work it domain by domain:

Master the linguistic levels first. Module 1 is half the test — be able to place any phenomenon at the right level (phonology, morphology, syntax, semantics, pragmatics, discourse).
Read a module, then check yourself. Take the end-of-module checkpoint to see exactly which sub-topics need another pass.
Practice applying, not just defining. CTEL 1 items are often scenarios — drill the flashcards and a practice test until you can match a situation to the right concept or theorist.
Rehearse the essay. Practice the constructed-response structure above on Domain 2 scenarios — name the principle, cite the evidence, recommend a justified response.
Check off as you go. Mark each section done in the Study Guide Contents — it raises your exam-readiness score.

Morpheme: The smallest unit of meaning in a language — 'un-', 'happy', and '-ness' are each a morpheme.
Phoneme: The smallest unit of sound that distinguishes meaning — /p/ and /b/ are separate phonemes because they distinguish 'pat' from 'bat.'
Phonetics: The study of the physical production (articulation) and acoustic properties of speech sounds, independent of meaning.
Phonology: The study of how a language organizes and combines its sounds, including the rules that govern which sounds can occur together.
Pragmatics: How meaning depends on context, speaker intent, and social rules — what an utterance does, not just what it literally says.
Register: The level of formality and style chosen to fit a situation, audience, and purpose.
Scaffolding: Temporary, targeted support (sentence frames, models, graphic organizers) that helps a learner do a task, then is removed.
Semantics: The study of meaning in language — the meaning of words and sentences, including denotation, connotation, and relationships among meanings.
Silent period: An early stage in which a learner understands more than they produce — listening and comprehending while speaking little.
Sociolinguistics: The study of how social factors — region, class, identity, setting — shape language use and variation.
Speech act: A pragmatic function performed by an utterance, such as requesting, promising, or apologizing.
Syntax: The rules for arranging words into grammatical phrases and sentences — word order, agreement, and structure.
Universal Grammar: Chomsky's proposed inborn capacity for language that lets children construct a grammar from limited input.
Zone of proximal development: Vygotsky's gap between what a learner can do alone and what they can do with guidance — the basis for scaffolding.
