Another important distinction is that norm-referenced tests are designed to evaluate a student's performance relative to the performance of other students. This helps parents and schools make regional and national comparisons. Standards-based tests, such as the WASL, emphasize the evaluation of each student's performance against a fixed and challenging standard of knowledge and skills. By the spring of 2001, all fourth, seventh and tenth graders in Washington's public schools will take the WASL in reading, writing, listening, and mathematics. Eighth and tenth graders will also take the science test.
Many private schools participate in the assessment as well.
Parents and teachers receive scores for individual students each fall. Scores show student performance relative to a high and fixed standard of achievement and provide information on strengths and weaknesses within each subject, such as problem solving in mathematics or grammar, punctuation and spelling in writing. Results provide teachers information about where students need help in these areas and can help refine instructional strategies in the classroom. Scores are also compiled to show performance trends at the school building, district and state levels. Teachers and education specialists developed specific scoring criteria for each subject tested.
