An AR is the chance to review the entire contents of the EHCP: the description of needs, provision, outcomes and the school named can all be changed by way of the AR process.
Done well, this is an (at least) yearly opportunity to ensure your child gets all the support they need but it is also an opportunity for an LA to remove provision, so it’s important to be well prepared to get the best out of it.
Reviews must happen within 12 months of the EHCP being finalised and then 12 monthly thereafter. For children under 5, reviews are more regular and there are specific rules when children are transitioning between stages of education.
Nothing agreed at an annual review meeting is legally binding unless it is included in an up to date EHCP, so it’s important to remember that the updated EHCP must be provided and checked.
