What does the ISACA CISM complexity score measure?

It measures how structurally demanding the questions are, not the official pass rate. We score every question in our ISACA CISM bank on four measurable signals and combine them into a 1-10 score. Higher means more multi-select items, longer scenario questions, more interactive code items and deeper explanations — that is, questions that require reasoning rather than recall.

Which ISACA CISM domain is the hardest?

By our measurement, Information Security Governance is the hardest domain in the ISACA CISM bank, scoring 2.1 out of 10. The most approachable domain is Incident Management at 2.0.

Is this the official pass rate?

No, and we do not publish one, because vendors do not release reliable per-domain pass rates. This is our own measurement of the bank. Treat it as a map of where the demanding questions sit in the blueprint, not as a prediction of your score.

Complexity by exam domain

Higher scores mean more demanding question formats. The exam score is computed over the whole bank, not averaged across domains.

How the score is calculated

The formula is fixed and public, so anyone can reproduce these numbers from the same bank.

Every question in the ISACA CISM bank is measured on four signals that can be read directly from the database. Each signal is expressed as a share of the questions in the domain, and the four shares are combined with fixed weights:

Multi-select questions (40% weight). Items with more than one correct answer. The candidate has to find all of them, which is the single hardest format in the bank.
Scenario questions (30% weight). Questions longer than 150 characters, which describe a situation instead of a definition and therefore test reasoning rather than recall.
Interactive questions (20% weight). Items that require reading code or a configuration snippet.
Deep explanations (10% weight). Questions whose explanation runs past 300 characters, which signals a concept with real nuance behind it.

The combined share is multiplied by ten to produce a 1-10 score. The exam-level score is computed over the whole bank rather than averaged across domains, so a small domain cannot distort the total. Figures on this page are recomputed from the live bank on every crawl.
