Guidelines for explaining standardized test results to parents of students are provided. More specifically, the guidelines cover rationales for testing, the various types of scores and their meanings, and means of interpreting scores. Scores covered include stanine scores, percentile scores, and grade-level equivalent scores. The importance to parents of learning who else takes the same test(s) as do their children is also considered. Test results provide teachers and parents with a powerful way of checking whether their students and children, respectively, are working to their full potential. A short bibliography is included.
