The Compass test is a computerized system for evaluating students’ incoming skill levels, used mostly by postsecondary institutions. It’s used to identify the courses that any given student should be placed in as well as academic areas that need more attention. One of these areas is writing skills.
Each test uses two parts: a Placement Test and a Diagnostics Test. As the name suggests, the Placement Test, in the end, shows what courses you should be taking. On the other hand, the Diagnostics Test shows your weaknesses and indicates areas that you should improve.
