RaraRachel, educational psychologists aren't qualified to diagnose anything and are probably best kept away from children. CAMHS diagnose.
The consultative role of educational psychologists involves wasting everyone's time in endless meetings (including over stretched CAMHS staff), pursuing their own research interests, (an EP actually said to us that our DC's case would make an 'an interesting wee research project' for her). Oh, and talking nonsense about My World Triangles, being patronising, displaying an extraordinary lack of empathy, seeing trauma as the explanation for all unwanted behaviours while failing to recognise trauma suffered by ASN children in primary schools and recommending that they are kept in 'environmental containers', i.e. grim cell like rooms, to make them self regulate. Apologies, I've gone off topic now but hate to see educational psychologists suggested as part of the solution to any child's issues.
