This pamphlet explains a child's Massachusetts Comprehensive Assessment System (MCAS) "Student Report for Parents/Guardians." In spring 1999, more than 210,000 students from grades 4, 8, and 10 in Massachusetts took the state's MCAS tests. All public students in grades 4, 8, and 10 are required to participate, and the Education Reform Law provides for no exemptions. Tests are given in English Language Arts, Mathematics, Science & Technology, and History and Social Science (grades 8 and 10 only). The student report provides a page of information about the child's performance for each content area in which a child was tested. Each page shows the subject area, the performance level achieved by the student, the total score for the subject area, and a display of score and probably ranges of scores. The report explains the performance levels (Advanced, Proficient, Needs Improvement, and Failing) with the score ranges for each level. Each page also shows how the student's performance compared with school, district, and state average scores. Comments about writing appear on the English language arts page of the student report.
