Thank you @DrRuthGalloway @BrumToTheRescue and @Farmhouse1234
@DrRuthGalloway He has complex needs and was non verbal until about two years ago, he's in his teens now. We're all aware he won't be able to live alone and requires constant supervision for safety not behaviour, he needs help/support with everything. His nepsy 11 comp of instruction had a scaled score of 1. The tests were administered with his previous 1:1 there and he engaged well.
He is also hyperlexic and can translate nouns in many languages, he just doesn't understand the meaning of the word he's translating always. He knows what a chair is but wouldn't be understand jealousy for example.
Would you expect a teen presenting like this to receive a ld dx? I don't want to pursue a dx unnecessarily (time and energy) but if he does and it does help with adult services then it'd be worth it.
