Exam Details for CISSP: Structure, Format, and Duration

Exam Structure and Format

The Certified Information Systems Security Professional (CISSP) exam is conducted in two formats depending on the language of the exam. For English-language candidates, the exam utilizes a Computerized Adaptive Testing (CAT) format. This adaptive system adjusts the difficulty of questions based on the candidate's performance as they progress through the exam. Candidates are initially presented with questions deemed below the passing standard, with subsequent questions adjusted in difficulty based on previous answers.

  • The CAT format consists of 100 to 150 questions.
  • Candidates must answer a minimum of 75 scored questions and a maximum of 125 scored questions.
  • The exam includes 25 unscored questions used for future test improvements.

For non-English languages, the CISSP is offered as a linear, fixed-form exam consisting of 250 questions over a six-hour period.

Duration

  • CAT format: Maximum of three hours.
  • Linear format: Up to six hours.

Passing Score Requirements and Retake Policy

To pass the CISSP exam, candidates must achieve a score that reflects a sufficient level of knowledge as determined by the (ISC)². The exact passing score is part of a standardized scoring system used across all test administrations.

If a candidate fails the CISSP exam, they can retake it after 30 days. However, there is a limit to three attempts within a 12-month period.

Types of Questions Included in the Exam

The CISSP exam includes multiple-choice questions and advanced innovative question types such as:

  • Drag-and-drop: Candidates must move answers to specific areas on the screen.
  • Hotspot: Candidates are required to identify specific areas within a graphic.

These question formats are designed to assess a candidate's ability across various domains critical to information systems security management.
