When ds1 was 7 we had a (private) assessment with an Educational Psychologist, because we were very concerned about his (lack of) awareness of all sorts of social skills. He just seemed very disinterested in other people and friends, and didn't seem able to get along easily with other children in group work or play.
He agreed with us that ds1 showed a number of signs of ASD/AS, and that it was not a major problem at the time (school were not concerned), but that we might consider a referral for a diagnosis when he was older. He also confirmed that ds1 was academically exceptionally bright, and agreed with school that this was one of the things causing him some difficulties socially, as he wanted to interact with children on a different level to what they were capable of.
He suggested that whether or not he had/has AS, the strategies that work well with children with AS would probably work with him. He told us something about them on the day, and more in his report, and gave us further information about reading material. He also put us in touch with the local AS advisor in the LEA SEN support unit, who gave me loads of material for ds1.
We used lots of strategies with him: modelling behaviour and talking through our thought processes; talking about social situations in advance and how people might be feeling, how they might react, how they might show those feelings in their speech or body language; role play; social stories; etc. Effectively we taught him strategies and behaviours and awareness that you might expect most children to pick up 'naturally'.

He is now very happy and settled and these worries seem a long way in the past. He's certainly a bit of an odd bod (nerdy geek), but he is extremely popular and makes friends easily now, he has loads of mates and a good number of close friends. He can be quite sensitive and aware of other people's feelings now, and is generally an all-round charming child. He's just started secondary school, and has made the transition relatively seamlessly. By all accounts he is a model pupil.
I still think he does have some difficulties, which might be described as being on the fringes of the AS part of the spectrum. But he is very bright and has learned how he needs to behave in order to fit in and be popular.
I still talk to him occasionally about new experiences and discuss what might be the best way to respond to something. But it's a long time since I wondered whether we might need to pursue the diagnosis route at some point, to help other people working with him.
