Peer Review

Time for a Peer review? 

Firms (and individuals) enrolled in the AICPA Peer Review Program are required to have a peer review, once every three years, of their accounting and auditing practice related to non-Securities & Exchange Commission (SEC) issuers covering a one-year period. The peer review is conducted by an independent evaluator, known as a peer reviewer. The AICPA oversees the program, and the review is administered by an entity approved by the AICPA to perform that role.

The peer review helps to monitor a CPA firm’s accounting and auditing practice (practice monitoring). The goal of the practice monitoring, and the program itself, is to promote quality in the accounting and auditing services provided by the AICPA members and their CPA firms. This goal serves the public interest and enhances the significance of AICPA membership.

There are two types of peer reviews: System Reviews and Engagement Reviews. System Reviews focus on a firm’s system of quality control and Engagement Reviews focus on work performed on particular selected engagements. A further description of System and Engagement Reviews, and Quality Control Materials (QCM) Reviews, as well as a summary of the nature, objectives, scope, limitations of, and procedures performed on them, are available online at or
