Our Experience Teaching ASE A4 Candidates To Pass The Exam

Teaching ASE (Automotive Service Excellence) A4 Suspension and Steering certification courses from a lecturer’s perspective can be both challenging and rewarding. This certification is crucial for automotive technicians, as it demonstrates proficiency in one of the most critical areas of vehicle maintenance and repair.

Crafting the ASE A4 practice exams has presented its fair share of challenges and fulfilling opportunities. Our coaching journey at Career Employer in this automotive field has been shaped by the exam’s wide scope, and the differing student needs, all at the same time aiming at exam success. Here are some of the teaching highlights: 


  • Strike a balance between theory and practicals: From a lecturer’s point of view, the key is to balance theoretical knowledge with practical, hands-on experience. It’s essential to cover the extensive range of topics required by the ASE A4 certification, such as diagnosis and repair of steering systems, suspension systems, wheel alignment, and wheel and tire issues. The challenge lies in ensuring that students not only understand these concepts in theory but can also apply them in practical scenarios.
  • Stay updated: A significant part of teaching this course involves staying updated with the latest automotive technologies. Vehicles are constantly evolving, especially with the advent of more sophisticated electronic and computer-controlled systems. As a lecturer, one must continuously update their knowledge and teaching methods to include these advancements.
  • Prepare students for the exam: Another critical aspect is preparing students for the ASE A4 exam itself. This involves not only covering the curriculum but also familiarizing students with the format and types of questions they can expect. This preparation can significantly increase their chances of passing the exam.
  • Engaging students as a priority. This can be achieved through interactive learning methods, like group projects, hands-on workshops, and real-world problem-solving scenarios. These methods help students grasp complex concepts more easily and retain the information better.
  • Professionalism and ethics: It’s important to instill a sense of professionalism and ethics in students. As ASE certification is a mark of quality and expertise in the automotive industry, we as educators emphasize the importance of continuous learning, attention to detail, and adherence to safety standards in our students.


  • Skill Development: There’s a great sense of accomplishment in helping students develop the skills they need to succeed in the automotive industry. Watching students grow from novices to skilled technicians ready for certification is highly rewarding.
  • Industry Impact: By training competent technicians, lecturers contribute significantly to the automotive industry’s standards and safety. This impact extends beyond the classroom to the quality of service customers receive in repair shops.
  • Lifelong Learning: Teaching ASE A4 certification encourages lecturers to be lifelong learners. They must continuously update their knowledge and skills, which keeps them engaged and passionate about their field.
  • Mentorship: Lecturers often become mentors to their students, guiding them not just in technical skills but also in career development and professional growth.

Effective Study Strategies / Methods

To effectively prepare for the ASE A4 exam, consider the following strategies and resources:

  • YouTube Study Guides and Tips: A YouTube video titled “ASE A4 Suspension & Steering – Test & Study Advice” provides insights into the exam, including study tips and areas to focus on. It’s a part of the ASE Master Technician Series by Driver’s Therapy. This can be a valuable visual and auditory learning resource.
  • ASE Official Study Guides: The ASE website offers detailed study guides for each test series. These guides include sample questions and suggestions for further preparation, acting as a roadmap for the individual tests.

  • Understand the Exam Structure: The ASE A4 Suspension and Steering exam consists of 40 scored multiple-choice questions. Additional unscored questions are included for statistical purposes but are indistinguishable from the scored ones, so thorough preparation for all topics is essential​​.
  • Start Preparation Early: It’s crucial to begin your study well in advance. A slow and steady approach, breaking down study time into smaller segments, is more effective than cramming information in a short period​​.
  • Focus on Weak Areas: After taking a practice exam, identify the areas you find challenging and concentrate your study efforts there. It’s generally more beneficial to strengthen weak areas than to review topics you’re already comfortable with​​.
  • Utilize Official and Third-Party Resources: While the official ASE website provides comprehensive study guides and practice tests, third-party websites also offer valuable materials. However, be sure to check the reputation and reviews of these third-party resources before using them​​.
  • Practice Tests: Regularly taking practice tests can help you get familiar with the exam format and identify areas needing improvement. 
  • Incorporate Various Learning Methods: Taking notes, visual learning, and teaching the material to others can enhance retention. Use illustrations, examples, and paraphrasing to reinforce understanding​​.
  • Set a Study Schedule: Establish a regular study routine in a quiet environment. Use workbooks and online resources for clarification on topics that are unclear​​.
  • Stay Calm and Focused: Maintain composure during the test, as a calm mindset aids in making logical decisions under pressure​​.
  • Explore Study Guides: Consider using comprehensive study guides like Motor Age ASE A4 Preparation and Halderman Steering and Suspension ASE A4 Test Prep, which offer updated questions and detailed explanations​​.

Remember, a combination of these resources can provide a comprehensive approach to your study, catering to different learning styles and giving you a well-rounded preparation for the ASE A4 exam.
