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

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