Thank you for all the information on this site, the membership fee was fully worth it!
My daughter was moved from IB to ESA in October and was wrongly placed straight into WRAG group without a medical. I wasn't sure whether to "rock the boat" at first after reading so many stories on the internet...
In the end I wrote a letter asking for a reconsideration quoting the applicable SG criteria in your guides. I had a letter 6 weeks later saying my reconsideration was successful! I didn't even have to appeal/provide further evidence or take her to a stressful medical.
Thank you again, and for those that are still struggling - don't give up hope
