The Pennsylvania Department of Public Instruction developed an information storage and retrieval system called PRIMES (Pennsylvania Retrieval of Information for Mathematics Education System). This system, designed to aid in elementary mathematics curriculum planning and implementation, was offered cost free to school districts; however, almost 90 percent of the invited districts chose not to participate. Focusing on the decision-making process in school districts, this study attempted to discover factors responsible for the large rejection rate. The main finding was that acceptance or rejection of the project was based largely on the degree of familiarity with the project. Administrators most likely to reject the project were those who had received little or no information about it.
