I am a Birmingham mainstream Primary SENCO. SENCO network meetings are held each term by Birmingham LA’s Pupil and School Support service (PSS) – I am unsure whether you will have that service being an independent school however they run a number of training courses which you can access on the Access to Education website.
This will also have the other LA services including the Communication and Autism Team, Sensory Support teams etc.
There is also the Educational Psychology Service:
Hope that helps. Let me know if there is anything else you need to know. Jess
