The Professional SAIs work stream aims to support SAIs in enhancing their professionalism and delivering high quality audits by moving towards ISSAI compliance.
INTOSAI P-12 calls on SAIs to carry out audits in accordance with their mandates and applicable professional standards. In keeping with the needs of SAIs and mandates given by INTOSAI, IDI has been supporting ISSAI implementation since 2012 through the 3i Programme. In 2019 the 3i programme was upgraded to the Professional SAIs work stream. Support for ISSAI implementation continues to be a high priority for SAIs, and INTOSAI’s Strategic Plan 2017-2022 emphasises the importance of ISSAI implementation and IDI’s role as "an essential INTOSAI mechanism for bringing together “on the ground” support for the implementation of professional standards".
