Focusing on current elementary and secondary school assessment practices as reported by a representative group of teachers and principals across Ontario, this study was designed around the following components: (1) an examination of current practices of school boards, school staffs, and individual teachers in the assessment of student achievement; (2) an analysis of the policies and practices developed by evaluation teams established by school boards; (3) the documentation of a broad range of assessment practices and related activities, e.g., recording and reporting student achievement, and utilization of computers; (4) the preparation of a small number of annotated current references on achievement testing; and (5) comparison of previous work on test utilization in Ontario with results obtained in the current study. A bibliography of reference materials for assessment, responses to a questionnaire, interview comments about ongoing assessment procedures, and a listing of assessment materials used by the interviewed teachers are appended.
