No requirement for maintained schools and academies
You're not required to produce post-inspection action plans.
However, by 8am on the day of your inspection, inspectors will want to see your current school improvement plan (SIP) or equivalent, including any planning that sets out the longer-term vision for your school, such as your school or trust's strategy.
This is set out in paragraph 82 of the School Inspection Handbook.
