Domain scores estimate a student's percent of mastery of each domain for the student's grade level. For example, a domain score of 53 for a fifth grader means the student would be expected to correctly answer approximately 53 percent of the fifth-grade items in that domain.
On the Star Diagnostic Report, each domain is broken down into specific skill areas. (For example, “Divide 4-digit by 2-digit: properties of ×/÷” is a skill area in the “Number and Operations in Base 10” math domain.) Again, the score shown by each skill area represents the student's mastery of the skills expected for the student's grade level.
Domain scores can be found in the following reports:
