The procedures used in developing test forms P and Q of the "Wisconsin Tests of Reading Skill Development: Comprehension" are described in this report. The criterion-referenced tests assess the 40 skills and objectives of the "Wisconsin Design for Reading Skill Development: Comprehension" commercial edition. The report contains individual test descriptions as well as general descriptive information regarding readability specifications, item content and test format, test directions, scoring and use of test results, and the tryout population. A rationale for test criteria, estimated summary statistics for both test forms, and actual summary statistics determined by administering the commercial edition are provided. Appendixes include the statement of skills and objectives for the test, estimated summary statistics for forms P and Q, item writing guidelines, and a list of selected "Design"-related studies.
