Certified Information Systems Auditor (CISA) Practice Tests

CISA tests whether you can plan, execute, report, and follow up on information-systems audits while evaluating governance, delivery, operations, resilience, and asset protection. The current weights are Audit Process 18%, Governance and Management of IT 18%, Acquisition, Development and Implementation 12%, Operations and Business Resilience 26%, and Protection of Information Assets 26%.

The exam has 150 multiple-choice questions in four hours. ISACA scores it from 200 to 800 and requires 450 to pass; registration is $575 for members or $760 for nonmembers, and exam eligibility lasts six months. Anyone may sit the exam, but passing does not by itself satisfy the separate experience and application requirements for certification.

Use these 895 questions to practise the auditor's sequence: establish scope and criteria, gather sufficient and reliable evidence, identify the root control issue, assess risk and impact, and communicate a defensible recommendation. CISA rewards independent audit judgment, so distinguish what an auditor should verify or report from what an operational team should implement.

CISA validates the knowledge and judgment used to audit, control, monitor, and assess information technology and business systems. The current outline has five domains: audit process, governance and management, systems acquisition and implementation, operations and business resilience, and protection of information assets.

The exam has 150 multiple-choice questions in four hours, uses ISACA's 200-800 scale, and requires 450 to pass. Passing is only the exam step; use of the CISA designation requires a separate application and qualifying professional experience.

CISA targets working IT auditors, internal auditors, IS audit managers, risk and compliance leads, and security consultants, particularly at organizations under regulatory scrutiny — banking, healthcare, government, and critical infrastructure — where a documented, standards-bound audit function matters. Because ISACA places no eligibility bar on sitting the exam itself, students and career-changers do register and pass CISA well before they've accumulated audit experience; the July 2025 CISA Associate designation exists specifically to give this group formal interim standing while they build toward full certification.

That said, the credential still rewards people already doing audit-adjacent work: at least 2 years of direct, verifiable IS audit, control, or security experience is mandatory for full certification no matter how many degree or certification waivers you apply, so candidates with zero audit exposure face a longer runway to full CISA (as opposed to CISA Associate) than the exam-only barrier suggests. Professionals already holding CISM, CISSP, or CRISC, or a relevant bachelor's or master's degree, reach full certification fastest, since those credentials cut up to 3 of the 5 required years.

ISACA sets no prerequisite to register for or sit the CISA exam. Using the CISA designation is a separate step that requires an application and qualifying professional experience under ISACA's current certification rules.

Candidates may therefore pass the exam before completing the experience requirement, but should read the official experience substitutions and application deadline before planning their certification path.

The CISA exam is 150 multiple-choice questions, each with a single best answer among four options, to be completed in 4 hours (240 minutes). ISACA reports scores on a 200-800 scale; 450 or higher passes. The exam mixes recall-based items with scenario questions — ISACA's own item-writing guidance notes that a stem may hinge on a qualifier like MOST likely or BEST, not just a technically correct answer — and a subset of unscored pretest items is seeded throughout without being flagged, so every question should be treated as if it counts. There's no penalty for wrong answers, and domain-level results are provided for information only; the overall scaled score alone determines pass or fail.

Scheduling has its own rules worth knowing before you register: once you pay, your eligibility window is six months, appointments open as early as 48 hours out and as far as 90 days ahead, and you can reschedule free up to 48 hours before test day (a $75 fee buys one additional six-month extension). If you don't pass, the retake clock isn't a flat 30 days: attempt 2 requires waiting 30 days from attempt 1, but attempts 3 and 4 each require a 90-day wait, capped at 4 attempts in any rolling 12 months, with the registration fee due fresh each time. A post-fail rescore is available for $75 if requested within 30 days of receiving your results.

CISA signals competence in planning and performing information-systems audits, assessing governance and controls, evaluating evidence, and communicating risk-based findings. It is relevant to IT audit, internal audit, assurance, risk, compliance, and security-control assessment roles.

The credential is especially useful where employers or regulators expect an established audit methodology. Holders must maintain it with continuing professional education, annual maintenance, ethics compliance, and ISACA's auditing standards.
