The document summarizes the development and testing of the South Dakota Regental Information Literacy Exam (SDILE), designed to assess information literacy skills among students in the South Dakota university system. A committee of librarians and faculty created a 25-item multiple choice exam based on the ACRL Information Literacy Competency Standards. The exam was analyzed using classical test theory and item response theory to validate its ability to both document minimum skills and assess varying ability levels. Initial testing showed potential but bureaucratic issues led to the exam being discontinued before it could be fully implemented.
