Internal evaluation is a process of reviewing and assessing a program or institution for its own purposes

It can be used to: 

Handle grievances In an educational setting, internal evaluation can ensure that student grievances are addressed fairly and promptly 

Improve performance Identify what contributes to good and poor performance, and develop a plan to improve .

Monitor quality Track efforts to improve and maintain quality over time .

Identify strengths and weaknesses In an educational setting, internal evaluation can help identify student strengths and weaknesses .

Internal evaluation is undertaken to assess what is and is not working, and for whom, and then to determine what changes are needed, particularly to advance equity and excellence goals.
