In 2012, Keith Curry Lance and his associates completed a second school library impact study in Pennsylvania. The research conducted in Pennsylvania was the result of an Institute of Museums and Library Services (IMLS) National Leadership grant that examined students' reading and writing scores with sub-groups of students (Hispanic, Black, economically disadvantaged, and disabled). This article will show how school librarians use research, in particular the 2012 Pennsylvania school library impact study findings, to cultivate stakeholders as school library advocates and possible champions.
