Hi manti1 - Welcome! Here is a link to common acronyms you'll find here:
http://giftedissues.davidsongifted....of_Common_Gifted_Acronyms.html#Post13990I'm sorry that your school does not get that kids can be gifted and have LDs too.

Hopefully you'll get some good info from Johns Hopkins that will help your son at school.
I'm sorry, I don't have any experiences with 2E (twice exceptional) kids or working with schools (my DS5 is just starting kindergarten), but I know there are others on this forum who have had similar experiences to yours. Good luck! I think you've come to the right place.
