# Stage 4: Approval

## 1. Appointment Letter

Upon successful application, you will be offered an Appointment Letter.

* Appointments commence upon receipt of the Appointment Letter and continue until terminated
* Vendors may only sell the specific solution version that was evaluated and pre-approved
* Pre-approval status does not guarantee or endorse the solution's quality or fitness for purpose, and must not be marketed as such

**Appointment Structure**

A review year runs for 12 months from the appointment date. For example, if appointed on 1st April 2025, the review year is 1st April 2025 to 31st March 2026.

Annual reviews occur in the 9th month of each review year. Passing vendors continue their appointment, while failed reviews may lead to suspension or termination.
