Best CASp Practice Questions 2027: What to Expect on the Exam

Understanding CASp Practice Questions

The Certified Access Specialist (CASp) examination is one of California's most challenging professional certifications, requiring extensive knowledge of accessibility codes, design principles, and field investigation techniques. As administered by the California Division of the State Architect (DSA), this comprehensive assessment demands thorough preparation through strategic practice question sessions.

Beginning with the February 2026 administration, the CASp examination tests to the 2025 California Building Code, making current practice questions even more critical for success. The examination's modified Angoff scoring method means that simply answering a majority of questions correctly may not guarantee a passing score-you need to demonstrate mastery across all domains.

Understanding what to expect on the exam begins with recognizing that the CASp assessment isn't just about memorizing code requirements. It's about applying accessibility principles in real-world scenarios, analyzing complex design documents, and making professional judgments that ensure compliance with both the letter and spirit of accessibility law.

Exam Format and Structure

The CASp examination consists of two distinct parts, each requiring different preparation strategies and practice approaches. According to DSA guidelines, the current examination structure includes both open-book and closed-book components, with timing and question distribution varying by administration.

Exam Component	Format	Approximate Time	Resources Allowed
Part 1	Plan Review	2 Hours	Open-Book
Part 2	General Knowledge	1.5 Hours	Closed-Book

The open-book nature of Part 1 doesn't make it easier-it actually requires more sophisticated preparation. You need to know not just what information to look for, but where to find it quickly within your reference materials. Our comprehensive CASp study guide provides detailed strategies for both sections.

The two-part structure reflects the dual nature of CASp work: detailed plan review requiring reference to specific code sections, and field assessment requiring immediate recall of fundamental principles. Practice questions should mirror this division, with some allowing reference materials and others testing immediate knowledge recall.

Domain-Specific Practice Questions

Each of the five CASp examination domains requires targeted practice with domain-specific question types. Understanding how questions are structured within each domain helps you prepare more effectively and identify areas requiring additional study.

Domain 1: General Knowledge and Skills

Questions in this domain typically focus on legal foundations, professional ethics, and fundamental accessibility principles.
