Ados assessment at camhs

Hi was just wondering if anyone could give me some advice , my 16 year old was diagnosed with adhd back in 2017 , we was seeing camhs who decided to do the ados assessment and in June this year we got told he also as asd , I was told we would receive a report and a statement that we could give his school to make sure he got the help he needs , waited 5 weeks to receive a letter just stating my son as adhd and asd , that he scored 17 point in section A and 1 point in section b . No information on what them scores mean , no report on how he got on in the ados assessment and now he been discharged from camhs . I was just wondering if this is all we should of received and does anyone know what these scores mean . Sorry for long post
