This document discusses different types of scheduling models for school library media centers. There are traditionally two main types - fixed scheduling, where classes visit the library on a set schedule, and flexible scheduling, where classes visit as needed in collaboration with the librarian. While fixed scheduling is most common, there is strong support for transitioning to flexible scheduling to better facilitate research, technology use, and information literacy skills. The document outlines pros and cons of each approach and provides examples of schedules. It also discusses obstacles to implementing the ideal schedule and strategies for librarians to make the most of their current schedule.
