Description: TRAILS is a freely available, Web-based tool to measure the information literacy skills of students in K-12. Assessments are standards-based and available at 6th and 9th grade levels, with 3rd and 12th grade coming in Fall 2010. After registering, librarians are able to create and administer a session. Following administration of the assessment, reports are immediately available at both student and class levels. TRAILS provides a means to diagnose student weaknesses and target instruction, as well as offer opportunities for teacher collaboration.
