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 Diagnostic Report's additional pages, each domain is broken down into specific skill areas. Again, the score shown represents the student's
mastery of the skills expected for the student’s grade level.
