Post assessment actions conducted

Version 1 - Last updated 28 Oct 2025

After completion of the on-site assessment on all the on-site assessment KPIs, the ZDHC Approved ETP Reviewer will prepare a report and will send it to the facility within five working days from the date of the on-site assessment. The reviewer should also share a copy of the report, categorisation of the supplier and all supporting documents/evidence, with the facility.

Corrective actions

Based on the results of the on-site assessment report (Alert, Level 1, Level 2) the facility should address the points of improvement and implement Corrective Action Plans (CAPs).

The supplier should then contact the ZDHC Approved ETP Reviewer for reassessment to improve the scoring in the next on-site assessment.
