Every tribunal has a legal chairman and two specialist members. Any new chairs and members are appointed by the Lord Chancellor on the advice of the Judicial Appointments Commission (JAC). There are currently 58 chairs, of whom 34 are women. In order to qualify, chairs need a seven year general qualification (within the meaning of the 1990 Courts and Legal Services Act).
There are currently 117 specialist members, of whom 65 are women. To qualify as members they must have knowledge and experience of children with special educational needs and be ineligible for appointment as panel chairs.
