What the Project Aims to Achieve

The objective of this workstream is to develop drafting principles and guidelines to address complexity, understandability, scalability and proportionality (CUSP) in developing International Standards on Auditing (ISAs).

Project Timeline

Please note that forecasted milestones are targets and are subject to change.

Current Status of the Project

At the April 2021 meeting, the IAASB discussed the Drafting Principles and Guidelines, which are designed to address complexity, understandability, scalability and proportionality (CUSP) in the ISAs. The Board strongly supported the Drafting Principles and Guidelines and noted that they will be useful in enhancing the consistency of future International Standards on Auditing (ISAs).

The CUSP Working Group is currently undertaking outreach with stakeholders to gather feedback on the Drafting Principles and Guidelines and we would like to invite you to complete a short survey. By answering these few questions, you will be contributing valuable information towards supporting the IAASB in finalizing its Drafting Principles and Guidelines.

As the CUSP project addresses many of the same issues and challenges as the audits of LCEs project, the two workstreams are running in parallel.
