CISSP CAT Exam Format Explained: How the Adaptive Test Decides Your Score
How the CISSP CAT exam decides your score, why hitting 150 items is not failure, and the adaptive testing strategy that actually works.
The exact change
"Adaptive testing is not about making the test easier or harder. It is about making each question maximally informative for the decision the test is trying to make. Candidates who feel the test is hard are usually the ones the model is most confident will pass." -- Mark Reckase, Professor Emeritus of Measurement and Quantitative Methods, Michigan State University ..."The only signal a candidate should trust is whether they applied the CISSP manager mindset consistently. The CAT will sort out the rest. Anyone trying to count correct answers is fighting the wrong battle." -- Clar Rosso, former CEO, ISC2 ...Both candidates would have done better if they had ignored their gut feeling about difficulty and trusted the Bruce Schneier principle that perception of security is not the same as security itself. ...A penetration tester, James, finished his exam at item 100 and walked out convinced he had failed because the questions had felt unrelenting. He passed...A compliance officer, Priya, ran to item 150 and felt the test had been generally easy. She failed.

Suggested change
De-attributed 2 fabricated named-expert quotes, corrected 1 misattributed/overreaching reference to a real expert's unrelated concept, and generalized 2 fabricated named-individual anecdotes to illustrative patterns.
Why this is better
De-attributed an unverified quote incorrectly attributed to Mark Reckase (real measurement professor) and an unverified quote incorrectly attributed to Clar Rosso (real former ISC2 CEO), corrected an overreaching claim that misattributed Bruce Schneier's unrelated 'security theater' concept as a named principle relevant to CISSP CAT scoring, and generalized an unverified named-individual anecdote (James, Priya) into illustrative patterns.
