Understanding CASp Pass Rates
The Certified Access Specialist (CASp) examination pass rate serves as a critical indicator of exam difficulty and candidate preparedness. Administered by the California Division of the State Architect (DSA), the CASp program maintains rigorous standards that directly impact pass rates across all examination categories.
Understanding these statistics is essential for prospective candidates planning their certification journey. The pass rate data reveals important insights about exam preparation requirements, common failure points, and success patterns that can inform your study strategy. With the examination fee set at $250 per attempt, plus application fees ranging from $100 to $500 depending on your category, understanding these statistics becomes financially important as well.
The CASp examination's two-part structure significantly influences pass rate patterns. Part 1, the open-book plan review exam, typically shows higher success rates compared to Part 2, the closed-book examination. This disparity reflects the different skill sets required: document analysis versus comprehensive knowledge recall under time pressure.
Candidates who fail the CASp exam most commonly struggle with Domain 2 (Prescriptive Requirements) and Domain 4 (Field Investigations), which together account for approximately 60% of exam content and require extensive memorization of specific code requirements.
Current Pass Rate Statistics
Recent data from DSA examinations reveals nuanced patterns in CASp pass rates across different categories and examination periods. The overall pass rate has stabilized around 68% over the past three years, representing a significant achievement given the examination's comprehensive scope covering all five domains of accessibility expertise.
Category-specific pass rates show notable variations that reflect the different experience requirements and candidate backgrounds. Category A candidates, typically architects with substantial accessibility experience, demonstrate the highest pass rates at approximately 74%. Category B candidates (engineers and related professionals) follow closely at 71%, while Category C (contractors and construction professionals) achieve a 65% pass rate.
| Candidate Category | Pass Rate | Average Score | First Attempt Success |
|---|---|---|---|
| Category A (Architects) | 74% | 78.2 | 76% |
| Category B (Engineers) | 71% | 76.8 | 73% |
| Category C (Contractors) | 65% | 74.1 | 67% |
| Category D (Inspectors) | 69% | 75.5 | 71% |
The examination's modified Angoff scoring method ensures consistent passing standards across different test administrations. This psychometric approach maintains fairness while accounting for variations in question difficulty, contributing to the relatively stable pass rate statistics observed over time.
Seasonal variations in pass rates also emerge from the data. Spring examinations typically show slightly higher pass rates (70-72%) compared to fall administrations (65-67%). This pattern likely reflects candidate preparation timing, with many professionals using winter months for intensive study before spring testing dates.
Beginning with February 2026, the CASp examination tests to the 2025 California Building Code. Historical pass rate data may not fully predict future performance as candidates adjust to updated code requirements and examination content.
Factors Affecting Pass Rates
Multiple variables influence CASp examination pass rates, with preparation quality emerging as the most significant predictor of success. Candidates who dedicate 150+ hours to structured study demonstrate pass rates exceeding 80%, significantly above the general population average.
