Quality Management at Engagement Level - ISA 220


The objectives of the project were to:

(a)   Propose revisions to ISA 220 to strengthen aspects of quality management for individual engagements by focusing on the identification, assessment and response to quality risks in a broad range of engagement circumstances.

(b)   Propose consequential amendments to other standards that may be necessary as a result of revisions to ISA 220.

(c)   Determine whether non-authoritative guidance and support tools should be developed by the IAASB or others to supplement the revisions or new standard(s).

The Board approved ISA 220 (Revised), which will be effective for audits of financial statements for periods beginning on or after December 15, 2022. Once the Public Interest Oversight Board’s confirmation that due process was followed is received, the Board will formally release the standard.

In finalizing the standard, the Board focused on clarifying the engagement partner’s responsibilities, the scalability of the standard, and the linkages with ISQM 1.
