# POST /api/v1/credit/underwriting/assessments/{assessment_id}/completion

> Complete an underwriting assessment

- **Tag:** credit
- **Operation ID:** `complete_underwriting_assessment_api_v1_credit_underwriting_assessments__assessment_id__completion_post`

## Description

Scores measured figures against the program's criteria set and closes the assessment. Returns per-criterion value, threshold, pass or fail, and source, plus roll-up counts and a weighted score. A criterion we could not measure comes back `passed: null` rather than false — those call for opposite actions. No recommendation is returned at any point.
