This paper describes two case studies of testing programs at local levels. The work was conducted as part of the Assessment Development and Use component of the Northwest Regional Educational Laboratory's (NWREL) Assessment and Development project. Two school districts were recruited to participate in this effort--McMinnville, Oregon, and Kyrene, Arizona. The draft case studies covered the demographics of each site, the testing system in place, the overall history of the activities, and the current status of each effort. Comparisons were made on the following subjects: (1) costs; (2) change agents; (3) role of technology; (4) curriculum alignment; (5) major issues and concerns; and (6) process of change. Extensive appendices attached to each case study provide background materials, such as five year curriculum plans, testing schedules, class profiles, philosophy of education, courses of study, program evaluation plans, and cost options.
