DS who is 21 is starting a PGCE this September; me, DH and DS all think he likely has ASD but doesn't have a diagnosis of ASD. I know it's not my place to interfere as DS is an adult but should I encourage him to mention his ASD to the uni and school he'll be placed in. Knowing DS he won't mention it and only might do if he started to seriously struggle. Also as DS doesn't have a diagnosis is there anything legally that could happen by declaring that he thinks he has ASD.
