298 questions · about 2 hours 21 minutes of timed testing (roughly 2.5 hours; ~3 hours to administer with breaks). No calculator. No penalty for wrong answers — so answer every question.
The five subtests split into two groups. The first two — Verbal Skills and Quantitative Skills — are that measure reasoning ability and produce the . The last three — Reading, Mathematics, and Language — are that measure what you have learned in school.[3] Every score is reported as a plus percentiles:
- Verbal Skills
- Quantitative Skills
→ Total Cognitive Skills + the Cognitive Skills Quotient (CSQ, average 100)
- Reading
- Mathematics
- Language
→ Total Basic Skills
Every score is reported as a standard score (200–800, mean 500) plus national and local percentiles and a grade equivalent. There is no fixed passing score — each school sets its own cutoffs.
No single subtest dominates — the 298 questions are spread fairly evenly, so balanced practice across all five wins.[1] Watch the pace, though: Verbal Skills packs 60 questions into just 16 minutes, while Mathematics gives you 45 minutes for 64. This guide teaches all five subtests in test order, each with its official skill clusters as subsections.
1 · Verbal Skills
60 questions in 16 minutes — the fastest-paced subtest. Verbal Skills measures word knowledge and verbal reasoning through four question types: synonyms and antonyms, analogies, verbal classification, and logic.[1] Because the clock is tight, recognizing the question type instantly and not over-thinking is half the battle.
60 questions in just 16 minutes — the fastest-paced subtest. Vocabulary is the biggest lever: synonyms, antonyms, and analogies all reward knowing the words.
Synonyms & Antonyms
A question asks for the word most similar in meaning to a given word; an question asks for the most opposite. Read the prompt word carefully — missing the difference between “most similar” and “most opposite” is a common, avoidable error. Predict your own answer first, then find the closest match among the choices.
Analogies
An gives a related pair of words and asks you to complete a second pair the same way. The key move is to state the relationship as a sentence before looking at the choices, then test each choice against that exact sentence — including its direction.
| Relationship | Example |
|---|---|
| Synonym | Big : Large :: Small : Tiny |
| Antonym | Hot : Cold :: Fast : Slow |
| Part to whole | Petal : Flower :: Branch : Tree |
| Type / category | Robin : Bird :: Trout : Fish |
| Tool to user | Brush : Painter :: Wrench : Mechanic |
| Cause and effect | Rain : Flood :: Spark : Fire |
Verbal Classification
questions list several words and ask for the one that does not belong. Find the category the others share, then spot the outlier. For example, in “rose, tulip, daisy, oak,” oak is the odd one out — the others are flowers, but an oak is a tree.
Logic
Logic questions give two statements and a conclusion, and ask whether the conclusion is true, false, or uncertain. Treat the statements as facts and reason strictly from them: if “all cats are mammals” and “Felix is a cat,” then “Felix is a mammal” is true. Beware conclusions that sound reasonable but the statements don’t actually guarantee.
Building Vocabulary
Three of the four Verbal Skills types reward knowing words, so vocabulary is the single biggest lever on this subtest. Study high-frequency roots and read widely; our flashcards drill the vocabulary the HSPT favors through active recall.
Checkpoint · Subtest 1 · Verbal Skills
Question 1 of 10
Identify the antonym of "Ineffable."
2 · Quantitative Skills
52 questions in 30 minutes. Quantitative Skills measures mathematical reasoning, not computation — number series, comparisons of geometric and non-geometric quantities, and manipulating numbers.[1] You rarely do long arithmetic; you spot patterns and relationships.
Number Series
A follows a hidden rule, and you give the next or missing term. Check the differences between terms first — a constant difference is an . If the differences grow, check the ratios — a constant ratio is a . Also watch for Fibonacci series and squares or cubes.
When a series stumps you, check the differences between terms first (constant difference = arithmetic), then the ratios (constant ratio = geometric), then whether two patterns alternate.
Geometric Comparisons
Geometric comparison questions show figures or shapes and ask you to compare quantities like the number of sides, areas, or shaded portions. Read each part — (A), (B), (C) — calculate its value, then compare. The answer is a statement such as “(A) is greater than (B), which is greater than (C).”
Non-Geometric Comparisons
Non-geometric comparisons do the same thing with numbers and operations instead of shapes — for example, comparing “one half of 20,” “one fourth of 40,” and “one fifth of 60.” Compute each value, then choose the statement that correctly orders them.
Number Manipulation
Number-manipulation questions are word puzzles: “What number is 3 more than half of 18?” Translate the words into operations step by step — half of 18 is 9, and 3 more is 12. Work left to right through the sentence and keep track of each step.
Checkpoint · Subtest 2 · Quantitative Skills
Question 1 of 10
What number is next in this series? 3, 6, 9, 12, ___
3 · Reading
62 questions in 25 minutes. The Reading subtest has two parts: comprehension (questions about passages) and vocabulary (the meaning of words).[1] The skill is answering from the passage in front of you, never from outside knowledge.
Comprehension & Main Idea
A question asks for the central point of a passage; a detail question asks for one specific fact it states. The main idea is the claim the whole text supports — broader than any single sentence, but never beyond what the passage actually says. Skim for the point first, then read for detail.
Inference & Structure
An is a conclusion the passage implies but doesn’t state. The correct choice is the one the text most directly supports — not the most dramatic one, and not one that needs facts the passage never gives. Structure questions ask how a passage is organized or why the author included something.
Vocabulary in Context
Vocabulary questions ask for the meaning of a word, sometimes as used in a passage. Use the surrounding sentence — its tone and logic — to choose the meaning that fits. Signal words like “but,” “because,” or “for example” hint whether a word is positive, negative, or being defined nearby.
Checkpoint · Subtest 3 · Reading
Question 1 of 10
In a work of fiction, what is the climax?
4 · Mathematics
64 questions in 45 minutes — the longest subtest. Mathematics covers concepts and problem solving across arithmetic, pre-algebra, and geometry.[1] No calculator is allowed, so fluent mental and written arithmetic matters. Start with the order of operations, which underlies almost everything:
The Mathematics subtest leans on this constantly. Multiplication/division and addition/subtraction are each a single left-to-right step — not strictly “M before D.”
- PParenthesesWork inside grouping symbols first.
- EExponentsThen powers and roots.
- MDMultiply & DivideLeft to right — whichever comes first.
- ASAdd & SubtractLast — also left to right.
Example: 8 + 12 ÷ 4 − 1 = 8 + 3 − 1 = 10. Division happens before the addition and subtraction.
Arithmetic & Number Sense
Master the , fractions, decimals, and percents. To find a percent of a number, convert the percent to a decimal and multiply: 35% of 120 is 0.35 × 120 = 42. To take a discount, multiply the price by the discount percent and subtract.
| Fraction | Decimal | Percent |
|---|---|---|
| 1/2 | 0.5 | 50% |
| 1/4 | 0.25 | 25% |
| 3/4 | 0.75 | 75% |
| 1/5 | 0.2 | 20% |
| 1/3 | 0.333… | 33.3% |
| 1/10 | 0.1 | 10% |
Pre-Algebra
Pre-algebra includes integers and signed numbers, exponents, simple equations, ratios, and proportions. To solve a one-step equation, do the inverse operation to both sides; to solve a proportion, cross-multiply. Remember the exponent rules: when multiplying like bases you add the exponents (so 7 to the 8th divided by 7 to the 3rd is 7 to the 5th).
Geometry & Measurement
Know the workhorses: area of a rectangle = length × width, area of a triangle = one half × base × height, and area of a circle = pi × radius². Perimeter is the distance around; a circle’s circumference is pi × diameter. Angles on a straight line add to 180°, and a triangle’s interior angles add to 180°.
| Shape / idea | Formula |
|---|---|
| Rectangle area | length × width |
| Triangle area | ½ × base × height |
| Circle area | pi × radius² |
| Circle circumference | pi × diameter (or 2 × pi × radius) |
| Rectangle perimeter | 2 × (length + width) |
| Triangle angles | Always add to 180° |
Problem Solving & Data
Word problems ask you to translate a situation into math. Read for what is asked, identify the numbers and the operation, then check that your answer is reasonable. Basic statistics show up too: the is the average, the is the middle value, and the is the most frequent value.
Checkpoint · Subtest 4 · Mathematics
Question 1 of 10
A bicycle that normally sells for 150 dollars is discounted by 30 percent. What is the sale price?
5 · Language
60 questions in 25 minutes. The Language subtest tests the mechanics of standard written English — punctuation, capitalization, usage, spelling, and composition.[1]
Many questions show three sentences and ask which contains an error (or none); others ask the best way to combine or revise sentences. These are some of the most learnable points on the test, because the rules are finite.
Punctuation
Know how marks join and separate ideas. The key idea is whether each side is an (a complete sentence). A comma alone cannot join two complete sentences — that is a .
| Mark | Use it to… |
|---|---|
| Period / semicolon | Separate two complete sentences |
| Comma + conjunction | Join two complete sentences (and, but, or, so) |
| Comma | Set off an intro phrase, a list, or nonessential info — not to join two sentences |
| Colon | Introduce a list or explanation after a complete sentence |
| Apostrophe | Show possession (the dog's bone) or contraction (it's = it is) |
Capitalization
Capitalize the first word of a sentence, the pronoun “I,” and proper nouns — names of specific people, places, days, months, holidays, and titles. Do not capitalize seasons, general directions (head north), or common nouns. Many Language items hinge on a single wrongly capitalized (or lowercased) word.
Usage & Grammar
Usage covers , verb tense, pronoun agreement, and commonly confused words. Match the verb to its real subject, ignoring words in between, and keep tense consistent.
| Rule | What to watch for |
|---|---|
| Subject-verb agreement | Match the verb to the true subject; ignore words in between |
| Pronoun agreement | A pronoun matches its antecedent in number (a team = 'it') |
| Affect vs effect | 'Affect' is usually a verb (to influence); 'effect' a noun (a result) |
| Verb tense | Keep tense consistent across the sentence |
| Double negatives | Avoid them — 'didn't see nothing' should be 'didn't see anything' |
Spelling
Spelling items show several words and ask which is misspelled (or that all are correct). Learn the classic patterns — “i before e except after c,” doubling a final consonant before “-ing,” and the most-misspelled words (necessary, separate, definitely, occurrence).
Composition
Composition questions test clear, effective writing: choosing the best topic sentence, combining two sentences smoothly, keeping , and spotting a sentence that doesn’t belong in a paragraph. Pick the version that is clear, concise, and grammatically correct — not the wordiest.
Checkpoint · Subtest 5 · Language
Question 1 of 10
Which of the following sentences uses a subjunctive mood correctly?

HSPT Glossary
Quick definitions for the terms you’ll see most across the HSPT:
- Analogy
- A Verbal Skills question that gives a pair of related words and asks you to complete a second pair with the same relationship (glove : hand :: sock : foot).
- Antonym
- A word with the opposite meaning of another word (happy and sad).
- Arithmetic series
- A number series in which each term differs from the previous one by the same constant amount (3, 6, 9, 12 — add 3 each step).
- Basic Skills
- The achievement half of the HSPT — the Reading, Mathematics, and Language subtests, which measure learned school content and feed the Total Basic Skills score.
- Battery Composite
- The Total Battery — a single summary score combining all five HSPT subtests.
- Cognitive Skills
- The reasoning half of the HSPT — the Verbal Skills and Quantitative Skills subtests. These feed the Cognitive Skills Quotient (CSQ) and the Total Cognitive Skills score.
- Cognitive Skills Quotient
- The CSQ, an ability score derived from the Verbal and Quantitative subtests. It has an average of 100 and is interpreted much like an IQ score.
- Comma splice
- A punctuation error in which two complete sentences are joined by only a comma. Fix it with a period, a semicolon, or a comma plus a conjunction.
- Geometric series
- A number series in which each term is the previous one multiplied by the same constant ratio (5, 15, 45, 135 — multiply by 3).
- Grade equivalent
- A score that estimates the grade level at which a student is performing, based on national norms.
- HSPT
- The High School Placement Test, published by Scholastic Testing Service (STS). A 298-question entrance exam taken mainly by 8th graders applying to Catholic and private high schools.
- Independent clause
- A group of words with a subject and a verb that can stand alone as a complete sentence.
- Inference
- A logical conclusion a reading passage supports but does not state outright. The best inference is the one the text most directly implies.
- Main idea
- The central point a passage makes — the claim every paragraph supports. Broader than any single detail, but never beyond what the text says.
- Mean
- The average of a data set: add the values and divide by how many there are. It is pulled toward outliers.

- The middle value of an ordered data set. It resists outliers.
- Mode
- The value that appears most often in a data set; a set can have one, several, or no modes.
- Number series
- A Quantitative Skills sequence that follows a rule (add, multiply, Fibonacci, squares). You identify the rule and give the next or missing term.
- Order of operations
- PEMDAS — the sequence for evaluating an expression: Parentheses, Exponents, Multiplication and Division (left to right), then Addition and Subtraction.
- Parallel structure
- Using the same grammatical form for items in a series (to read, to write, and to study — not to read, writing, and study).
- Percentile rank
- A score from 1 to 99 showing the percent of test-takers a student scored above. The HSPT reports both a national percentile and a local percentile.

HSPT Study Guide FAQ
The HSPT has 298 questions across five subtests: Verbal Skills (60), Quantitative Skills (52), Reading (62), Mathematics (64), and Language (60). Each subtest is separately timed.
The five timed subtests take about 2 hours and 21 minutes total (16 + 30 + 25 + 45 + 25 minutes), often rounded to about 2.5 hours. With instructions and breaks, schools usually allow around 3 hours to administer the whole test.
Each subtest and composite is reported as a standard score (200–800, national mean 500), plus national and local percentile ranks and a grade equivalent. The Verbal and Quantitative subtests also produce a Cognitive Skills Quotient (CSQ) with an average of 100.
There is no official passing score. The HSPT is a placement and admissions test, and each school or diocese sets its own cutoffs for admission, course placement, and scholarships. Aim for the score range your target schools expect.
No. You earn one point for each correct answer and lose nothing for a wrong or skipped answer, so you should answer every question — even if you have to guess on the ones you run out of time for.
No. Calculators are not allowed on any HSPT subtest, including Mathematics, unless a student has approved accommodations arranged with the test site in advance. Practice your mental and written arithmetic.
The HSPT is taken mainly by 8th graders applying to Catholic and private high schools. STS recommends taking it only once, and most schools allow it once per admission cycle; if a student tests more than once, the lowest score is typically the one reported.
Work through the five subtests in order — Verbal Skills, Quantitative Skills, Reading, Mathematics, and Language. After each subtest take the checkpoint quiz to find gaps, then drill that area with our free practice questions and flashcards before test day.
