When an employer has an SNA vacancy to fill, they must undertake the recruitment process in accordance with the provisions outlined in Circular 0042/2017 “Recruitment of Special Needs Assistants (SNAs) –Supplementary Assignment Arrangements for the 2017/18 School Year” - https://www.education.ie/en/Circulars-and-Forms/Active-Circulars/cl0042_2017.pdf
The supplementary assignment arrangements for Special Needs Assistants (SNAs) were established on foot of proposals brought forward by the Labour Relations Commission (LRC) when the Haddington Road Agreement was being agreed. These supplementary assignment arrangements for SNAs continue to operate under the Public Service Stability Agreement 2018 - 2020, and both unions representing SNAs, namely SIPTU and IMPACT, have signed up to that agreement. As set out in the LRC proposals, the supplementary assignment arrangements for SNAs only apply to current SNAs who are notified that they are to be made redundant. Accordingly, the purpose of these arrangements is to facilitate eligible SNAs who are being made redundant by one employer in filling SNA vacancies that may become available in another school / ETB.
It should be noted that this does not prevent any person from applying for SNA vacancies but employers are obliged to give precedence to applicants who are members of the SNA Supplementary Assignment Panel.
