The purpose of this article is to illustrate the work that has resulted from a collaboration between a biology professor, a school psychology professor, a researcher in higher education access, and the writing programs director. The essential school psychologist role, as classroom observer and data analyzer, is discussed through an example of work done as part of a larger project focusing on student success and retention for at-risk populations in introductory college biology courses. Best practices for consulting at the college level are discussed and include: collaborate to cultivate the willing, collect and analyze data to sustain instructor involvement, and communicate and advocate. We hope that the model exemplified here might inspire future interdisciplinary collaborations that draw on school psychology expertise to design and conduct research.
