I think it depends on a few things- do you feel that the child is in need of an EHCP? If so, the applications are often stronger if completed by the school as you will likely have a better understanding of what criteria is necessary, and how to write it to include ‘buzz words’ etc. and it also shows that you are in support of the application.
If you don’t feel the child needs an EHCP, you can continue with your APDR cycle and provision maps- reassuring parents you are doing all you can do support their child and that their needs can be met through this additional support.
Tribunal is also an option- regardless of who has written the EHCP request, only the parent or young person can appeal. There is more information about the process here:
