In recent decades, the work of educational developers in Centers of Teaching and Learning (CTLs) is complex and diverse. The wide range of services and programs makes it difficult understand the mission and purpose of CTLs and communicate this effectively. The Center Mission Matrix Tool enables analysis and articulation of all facets of the Center's mission. Juxtaposing the Center mission with three levels of impact--individual, departmental, and institutional--the Matrix adapts to each Center construct and provides a visual snapshot to multiple audiences, including the field of educational development, institutional stakeholders, and to the Center staff for internal purposes.
