# Functional Configuration

There are various configurations that can be made via the Batch Service:

* Batch type: Open (users can enroll by themselves)
* Batch Start date and End date and Enrolment End date
* Certificate generation for batch
* Criteria for earning a certificate (minimum score for the course assessment)

Following are the functional [configurations](https://github.com/project-sunbird/sunbird-devops/blob/release-5.4.0-lern/ansible/roles/stack-sunbird/templates/sunbird_lms-service.env)
