High School and college librarians are collaborating on information literacy instruction to support student success. Salem-Keizer High School Teacher/Librarians and Chemeketa Community College Librarians used a district inservice day to share instruction, work on K-12 to college alignment, and to articulate research expectations in High School and college classes. We share students, we advocate for each other, our work is complex, and we are committed; this is not a short-term relationship! We'll talk about what we've learned and how we've used our experience so far, and about our next steps. Attendees will gain insight and practical tips for creating similar professional development communities, and will hear ideas for capitalizing on existing communities in other districts. We are happy to provide access to our instructional materials.
