The Third CLASS Research Forum on Thursday, January 23, 2020 in Philadelphia prior to the American Library Association Midwinter Conference focused on CLASS II, a recent effort to surface causal research findings from education research regarding positive learner outcomes that can be enacted by a school librarian. This research included an aggregation of findings from almost four decades of high quality published causal research; a distillation of effective practices potentially translatable to school librarianship; implementation of small scale field-based applications; and the building of testable conjectures that relate educational research to school library practice. A report of CLASS II findings regarding learners, school librarians, and school libraries was peer reviewed during the forum. This session will include Research Forum highlights, including excerpts from Dr. Annie Allen's (University of Colorado at Boulder) keynote address, and forthcoming research report features. CLASS II researchers will engage participants with ways to get involved with this important, ongoing work.
