This paper investigated the reliability and validity of the National Survey of Student Engagement's Experiences with Information Literacy module, an assessment instrument developed in collaboration with a group of instructional librarians. After identifying three information literacy-related factors in the module, it assessed the relationship between the factors and students' engagement in Higher-Order Learning and Reflective and Integrative Learning activities and students' perceived gains. The results from these analyses indicated that information literacy activities were positively and significantly correlated with student engagement and students' perceived gains.
