Wikipedia, the free online encyclopedia that can be edited by users, is growing both in the number of content articles written as well as the number of registered users. Students rely on Wikipedia (Purcell et al., 2012) and Wikipedia, through tools, is enabling users to make better decisions regarding the information they find (Gray, 2013; Kyrios, 2013; Lamb & Johnson, 2013). However, are teachers and librarians in secondary schools learning to embrace the online encyclopedia? This exploratory study surveyed classroom teachers and librarians/library staff regarding their perceptions of the effects of Wikipedia use by students in research assignments, their perceptions of the need for school policy regarding the use of Wikipedia by students, and regarding their knowledge of the Page Assessment Guide designed to help users judge the reliability of the information on a page.
