Being 19 and in school Sixth Form is not an issue for an immature girl . I would actually see that as benefit. However, Posters on here seem to think everybody by the age of 18 should be living independent lives, running a household and having no influence or guidance from their parents.
I would not be bothered if Goddaughter stayed in the schools Sixth Form until 21 ! Thus, if she came out with 3 D grades at A Level no problem she can redo them later. Academic grades despite what posters think are not the be all and end all here.
When her mother took her to visit an F.E College, she refused to enter the building because of fear of the unknown.

I am fearful this could happen to my Goddaughter just for being Autistic, different and acting in a manner which is not considered normal for a 18 year old girl. (I am going to start a thread about how some young vulnerable Autistic people in 'Care' homes are treated worse than how Wayne Cousins will spend his time in Prison). This can and does happen to academically able Autistic (whether that's below Mumsnet average ).
I want her in a place where she is comfortable, familiar. Therefore, not likely to freak out not knowing the terms of the place , the actions of individuals and the social structures around her
P.S the authorities wanted me placed in one of these type of facilities, despite having 3 B's at A Level. So don't suggest that the (Academically Average can't end up in these places).
