My Department understand from engagement with your office that the individual referred to in this parliamentary question is a teacher employed by an Education and Training Board (ETB).
Each school Board of Management or ETB has sole responsibility for the appointment of its teachers. The ETB is a statutory body with its own corporate status established under the Education and Training Boards Act 2013. Terms and conditions of employment for staff employed by ETBs are matters for the ETB concerned. While the recruitment and appointment of teachers to fill teaching posts is a matter for the individual school authority or in this case ETB it is subject to procedures agreed under Section 24(3) of the Education Act 1998 (as amended by the Education (Amendment) Act 2012).
