CIA Part 1: Internal Audit Fundamentals

Part 1 tests the fundamentals the whole profession rests on: the purpose and standards of internal auditing, ethics, governance, risk management, control and fraud. Foundations alone is 35% of the exam.

Why take the CIA?

If internal audit is your career, or you want it to be, the CIA is the credential the profession is built around.

  • The global mark of an internal auditor

    The CIA is The IIA’s flagship certification, recognised by employers and audit committees around the world as proof that you know the profession’s standards and can apply them.

  • Built on today’s Standards

    The exams follow the 2024 Global Internal Audit Standards, so what you study is what the profession now expects in practice: purpose, ethics, governance and quality.

  • Roles it opens

    Internal audit at every level, risk and compliance, controls and assurance roles, and the path to leading a function that reports to the board.

  • A route that fits you

    Sit three parts in any order within three years, or, if you’re an approved CPA or CA holder or a qualified CISA holder, one Challenge Exam instead.

Where Part 1 fits: most candidates start here. It lays the foundation (purpose, ethics, governance, risk, control and fraud) that Parts 2 and 3 build on.
