Assess, Plan, Do, Review (APDR)

Settings should adopt a graduated approach with four stages of action: assess, plan, do and review (APDR) to ensure that CYP's needs are fully understood and met (The Graduated Approach: Assess, Plan, Do Review - SEND Code of Practice 2015, pp100-102). 

This is called the graduated approach/response because it may take several cycles of intervention, and the use of different strategies, before support needs are fully understood and effectively met.
