The Constitution of Boards and Rules of Procedure document 2011 sets out the procedures for appointment of teachers, including the composition of the selection board. These rules were agreed by the education partners and the revised document applies to new Boards of Management as of 1st December 2011. Under those rules, a selection board for teaching posts must comprise the chairperson of the board of management, the principal teacher and an assessor independent of the board of management, to be appointed by the patron after consultation with the chairperson of the board.
A copy of the rules is available on my Department's website —www.education.ie.
