The Education Endowment foundation published their report on evidence implementation in schools. Here are their recommendations:
recommendation 1: treat implementation as a process, not an event; plan and execute it in stages
recommendation 2: create a leadership environment and school climate that is conducive to good implementation
recommendation 3: define the problem you want to solve and identify appropriate programmes or practices to implement
recommendation 4: create an implementation plan, judge the readiness of the school to deliver that plan, then prepare staff and resources
recommendation 5: support staff, monitor progress, solve problems, and adapt strategies as the approach is used for the first time
recommendation 6: plan for sustaining and scaling an intervention from the outset and continuously acknowledge and nurture its use
