CCA Passing Score Explained: What a Pass Actually Takes
Scaled scores, unscored pretest items and a passing standard that is not a percentage — here is how the CCA is actually marked.

What the passing standard actually is
ISACA, which runs the CCA exam as the CMMC Assessor and Instructor Certification Organization (CAICO), reports results as a scaled score from 200 to 800, and you need 450 or higher to pass. That is a scale point, not a percentage: there is no published “get 70% and you pass” rule to aim at, and a raw percentage from a practice test does not translate directly into a verdict on the real exam.
The score maths
Scaled scoring exists so that a candidate who sits a slightly harder form is not punished for it. Raw answers are converted onto a fixed scale, and the conversion moves a little between forms. That is why the certifying body publishes a scale point rather than a question count: the number of items you can afford to miss genuinely is not a constant.
Why some questions do not count
Most professional certification exams seed unscored pretest items into live forms to gather statistics for future versions, and they are never flagged to the candidate. Assume every question counts, because you have no way to tell which ones do not.
What the pass rate tells you
ISACA does not publish a headline pass rate for the CCA exam, and the numbers circulating on forums are usually someone’s cohort rather than a national figure. Treat any percentage you cannot trace to the certifying body as decoration.
What this means for your study plan
Three things follow from how this exam is marked.
Stop chasing a percentage. A practice score of 72% is not a prediction, because the conversion between raw answers and the reported scale is not published and moves between forms. What a practice score is good for is finding the domains where you are weak.
Answer everything. There is no negative marking on this style of exam, so an unanswered item is a guaranteed zero where a guess is not. Candidates lose real points to the clock, not to the content.
Work in volume, not in re-reading. Recognition feels like knowledge and is not. The only reliable signal that you are ready is a large number of unfamiliar questions answered correctly under time pressure.
That last part is what a question bank is for. Practise CCA questions free, then work the domains your results expose.
FAQ
What is the passing score for the CCA?
ISACA reports CCA results on a scaled score from 200 to 800, and 450 or higher passes. The scale is not a percentage, and your result is based on the total number of questions answered correctly, regardless of domain.
How many questions can I get wrong on the CCA?
The raw-to-scaled conversion is not published, so any specific number of allowed misses you see quoted is someone's guess rather than a rule.
What is the CCA pass rate?
ISACA does not publish a headline pass rate for the CCA exam. Figures on forums describe single cohorts, not the national result.
Do unanswered questions count against me on the CCA?
An unanswered item scores zero, and there is no penalty for a wrong guess, so there is never a reason to leave one blank. Watch the clock and make sure every item has an answer before time expires.
