: The biggest barrier is often the school’s reliance on the librarian to provide prep time for classroom teachers.

Integrating library skills into classroom content through collaboration leads to significantly better student outcomes than teaching library skills in isolation.

: Many experts suggest building strong collaborative relationships with teachers while still on a fixed schedule. Once teachers see the value of the librarian as a co-teacher, they are more likely to support a flexible schedule.

: It can be difficult to convince teachers to give up their set library time or to find time in their busy schedules to plan with the librarian.

: Some librarians find that a lack of scheduled checkout times makes it harder to connect with every student. Many successful programs maintain a "fixed-flex" hybrid where book checkout remains somewhat regular while instruction is flexible.

: Research indicates that schools with totally flexible schedules often see significantly higher per-pupil book circulation. Best Practices for Implementation

: A modern term adopted by the American Association of School Librarians (AASL) that emphasizes an open, unrestricted schedule shared by the entire school community to provide equitable access to resources and the librarian's expertise throughout the day. Benefits of Collaboration and Flexibility

: Flexibility allows for longer blocks of time—multi-day projects that cannot be finished in a standard 30–45 minute fixed period.
