Thanks guys, I thought I was missing out on something lol, I assume these are just for Type 1's 🙂
makes sense but this article suggests it stands forBERTIE - Bournemouth Type 1 Intensive Education
Looks like they were a bit liberal with the placment of the 'E' 😉
There's another one called SAILING (? Southampton or Portsmouth, not sure) and PASTIE (which rather surpisingly I believe is in Devon!)
