The reconceptualisation of school placement (Teaching Council, 2013) poses a challenge to initial teacher education in Ireland. Some criticised the timing (Mulcahy and McSharry, 2013). Others considered it to be too great a professional leap (O’Grady, 2017). This study sought to explore if and how cooperating teachers could develop as mentors in the Irish context, through engagement in a ‘participatory action learning action research’ (PALAR) ‘mentoring community of practice’ (M-CoP). Qualitative data collection methods included: questionnaires with stimulus recall, pre-workshop questions, (...) workshop observation, workshop artefacts, reflective journals, learning journey plans, and extended focus group discussions. Data were analysed via constant comparison of codes and categories. CTs reported that their transformed practice as a mentor and a leader was achieved due to the multi-process, meta-pedagogical, meta-model design of the PALAR M-CoP. They indicated that the meta-model enhanced their fluency in the ‘language of critique’ enabling them to identify and become exercised about a range of complex barriers to growth. It also developed their fluency in the languages of ‘possibility’ and ‘leadership for change and empowerment’, which aided them to cope with, and overcome barriers to growth, resulting in the empowerment of themselves and other school placement partners.
