How can we cancel an EHCP for Year 11 and college?

Hi OP, Im a retired sendco. Anything to do with changing EHCPs was highly problematic with my LA.
If a parent had requested to cancel one, I would have made sure it happened and I would have reached out to colleges to explain why. But not everyone in send thinks like me.
Get the sendco involved and point out that the person it is supposed to help ie the student has requested this.
There is no reason apart from institutional inertia why this cant happen. Ask the sendco to remove the coding E from the schools admin systems as well.
You and your child are by no means the only people who have found EHCPs to be unhelpful, many of the strategies in EHCPs are not appropriate in the GCSE and college settings. Actually lots of them are not helpful in secondary school at all. Again though my opinions are very much not part of the orthodox send thinking.
Good luck.

Counter thought here - I would keep it in Year 11 - it may be beneficial for getting any additional exam access requirements your daughter could benefit from. Even small things like the English speaking exam which is very informal may be daunting for a child with even a mild language disorder. At transition planning meeting for college then is maybe a better time to ask for the plan to end.

Wow that’s shocking. They are usually desperate to remove plans if suggested by school and professionals. I am a SALT and I have sat in a few reviews where we have decided that the EHCP is no longer needed and it has been removed by the local authority. I might see if you can get supporting letters from professionals although I know that would take time and probably only for the next review

If it’s not valid this should have been spoken about during the annual reviews? The annual reviews happen for this exact reason?
