Could I have a list of all the schools within your region that have a SENCO? If I could have the name, telephone number & email address of the SENCO too, that'd be very helpful. Otherwise, a basic list of the schools where a SENCO is employed will suffice.
I can advise you that the information you require is held by Essex County Council and not Brentwood Borough Council.
