Your next steps will depend on whether your child has a statement or not.
What to do if your child does not have a statement
If your child does not have a statement and you don't feel happy about the school you have been offered, you can appeal to the school admissions panel.
What to do if your child does have a statement
If your child has a statement and you disagree with the school named by the local authority, you can appeal to the Special Educational Needs Tribunal. However you must lodge your appeal within 2 months of receiving the final decision letter from your local authority. You should also write to your named officer at the local authority, telling them that you do not agree with the statement and that you wish to go to the Special Educational Needs Tribunal. You may also want to request a meeting to discuss your concerns about their decision.
At the same time, you can also contact the Disagreement Resolution Service, which is sometimes known as a mediation service – your local authority should give you their details. Using the mediation service does not affect your right to appeal to the tribunal. However, if meeting with your local authority and using the mediation service is enough to resolve the disagreement you can withdraw from the tribunal process.
