If you want DS to attend full-time, he can unless the school is formally suspending DS. You don’t have to allow the school to continue to unlawfully, informally exclude DS.
If the provision detailed, specified and quantified in F isn’t being provided, it can be enforced. It is the LA who is ultimately responsible for ensuring the provision is provided. IPSEA has a model letter you can send. If that doesn’t work, you need a pre-action letter. Then, if that fails, judicial review proceedings will resolve the situation. However, the provision can only be enforced the provision is detailed, specified and quantified in F. If F is woolly and vague with wording such as “access to”, “or equivalent”, “opportunities for”, “as appropriate”, “would benefit from”, “regular”, “up to”, “would be useful/helpful”, “such as”, “e.g.”, “as required”, “as advised”, “key adult(s)”, “small group” it cannot be enforced. You should use the review process to try to tighten up the wording and, if necessary, appeal when you have the right of appeal.
If you wish to move placement, you can make it known during the review. Following the AR meeting, the LA must inform you if they are going to amend or not within 4 weeks. If they aren’t going to, you will have to right of appeal. If they are going to amend, they must send the amendment notice. At that point, you will be able to make representations state your preferred placement. Then the LA must finalise within a further 8 weeks. Once the LA finalises, you will have to right of appeal.
Depending on when your annual review is next month, asking for an early review may not be any quicker, anyway.
