# Quality Scoring

## Stakeholder-specific Scoring

The **Quality Score** is based on the quality of contributions from the specific user. Depending on the role of the user, this has a slightly different meaning.&#x20;

### Contributors

For contributors the Quality Score is based on the feedback of Reviewers and Clients.

### Reviewers

For Reviewers the Quality Score is based on the reviewer consensus and the feedback of Clients.&#x20;

* If the reviewer consensus agrees with the individual reviewer this results in a positive quality score and vice versa
* If the client feedback corresponds with the reviewer feedback this results in a positive quality score and vice versa

### Clients

The Client Quality Score is based on the comparison between client feedback and reviewer consensus.&#x20;

* If the client feedback corresponds to the reviewer consensus, this results in a positive quality score and vice versa.&#x20;

## Calculating the Quality Score
