# 4.3 Materiality Threshold

The threshold for materiality is 5% for all Projects. The discrepancy between reported mitigation outcomes and what the auditor determines to be the real mitigation outcomes must not exceed this threshold.

Materiality issues can also be of a qualitative nature. These can be identified and documented, such as:

* control issues that erode the verifiers confidence in the reported data;
* poorly managed documentation;
* difficulty in locating requested information.

If a project is found to be overcrediting, after credits have been issued, see the NCS policy on reversals ([5.6](/readme/5-crediting/5.6-reversals-and-buffer-pools.md)).
