As part of the University of Rhode Island Libraries' "Comprehensive Plan for Information Literacy," a three-credit class in the skills and concepts of information literacy was first offered in the fall of 1999. More than 1,000 undergraduate students have taken the class since that time. A pre-test was given at the beginning of each semester, followed up by a post-test at the end. The pre- and post-test results were analyzed to determine: (1) whether students improved their test scores over the course of the semester, (2) which concepts and skills students mastered, and (3) where the course might need revision and/or improvement. Analysis showed that skills were acquired and/or improved overall.
