IDI Performance Audit ISSAI Implementation Handbook

We are delighted to present to you Version 1 of IDI Performance Audit ISSAI Implementation Handbook.

Developed through a collaborative process, the Handbook aims at providing guidance and presenting one of the possible ways in which you can implement Performance Audit in accordance with International Standards of Supreme Audit Institutions (ISSAIs).

The Handbook contains explanations of the ISSAI performance audit process and audit working-paper templates designed to facilitate the application of ISSAIs in practice.

The Handbook was developed from the auditor’s perspective. It may be used and adapted by all public-sector performance auditors. The methodology suggested covers the audit work to be performed and documented at an audit engagement level. The Handbook may also be used by organisations supporting SAIs in developing audit methodology for performance audit.

Revised Performance Audit Handbook

The Performance Audit ISSAI Implementation Handbook went through a light touch review at the end of 2023 to ensure that this Global Public Good stays relevant.

By updating this key resource, IDI aims to continue to support SAIs in implementing the latest performance auditing standards and carrying out high-quality, standard-compliant audits that adhere to international best practices. 

We sincerely hope that you find the Handbook useful for your work.

The revised Handbook is available in English, French, Spanish and Arabic.
