The California Assessment Program (CAP) administers tests to all public school students at certain grade levels, compiles the results, and provides information that allows educators to judge the effectiveness of their programs and make improvements. This sampler describes the types of assessment that CAP proposes to respond to the needed changes that reflect the recent curricular reforms in schools throughout California. The four types of assessment planned for CAP are: (1) open-ended problems; (2) enhanced multiple-choice questions; (3) investigations; and (4) portfolios. These modes of assessment are recommended for adaption for teachers of all grade levels and teachers are encouraged to use the examples in the booklet to enhance classroom instruction and to develop tasks for student assessment. After chapter 1 that describes the changes in assessment, the sampler is divided into six major parts: chapter 2, "Assessment of Mathematical Power"; chapter 3, "Types of Assessment"; chapter 4, "Performance Standards and Judging a Student's Work", chapter 5, "Implementation of Authentic Assessment in Your School," chapter 6, "Sample Problems." A "Participation and Feedback" page is given to ask participants' comments and suggestions about the sampler. (11 selected references) (MDH)
