This report describes a decision-making tool designed to inform special educators of the most up-to-date participation and test accommodations guidelines and to assist educators in the process of making informed decisions. It reports on the results of a study that examined the tool's feasibility and practicality. The decision-making tool is an electronic version of Minnesota guidelines for making test participation decisions. The Web site design has two branches, one for students with disabilities and another for students with limited English proficiency (LEP); both are centered on making decisions about inclusion and the use of testing accommodations. The Web site design has two branches of decision making to reflect the dual role of the tests within both the LEP and disability branches--one for statewide accountability testing for grades three, five, and eight, and one for graduation requirements testing for grades eight and beyond. A survey of 8 special educators, 5 parents, 1 administrator, and 1 school psychologist found that 10 thought the format of the tool was easy to understand, 8 would use the tool again, and 11 would recommend the tool to others. Appendices include an overview of the decision matrix and the survey. (Contains 16 references.) (CR)
