Figure 4-1 is an example of a school report that was developed by the National Center for Research on Evaluation, Standards, and Student Testing for the Los Angeles Unified School District. It shows a range of information on student performance—including test scores, course taking, and graduation rates—along with contextual information about the qualifications of teachers and the students' background. The test the district uses includes norm-referenced reports rather than standards-referenced reports. In addition, the report does not indicate the degree of statistical uncertainty of the test scores.
