A whole school approach to guidance counselling has been promulgated by Irish policy-makers as a model of good practice in the delivery of guidance counselling in the post-primary sector since the 1998 Education Act (DES, 2005a, 2009, 2012). This approach to guidance counselling provision is viewed as a whole school responsibility where schools are expected to collaboratively develop a school guidance plan to support the needs of their students. The role of the regular teacher in a whole school approach to guidance counselling has received very little attention either in the Irish education system or in empirical research. This article will address this deficit through its discussion of a case study carried out in one school in 2012. It will position the findings from the study in the context of the re-allocation of post-primary guidance counselling provision in the national Budget 2012 that has witnessed the substantive erosion of the guidance counselling service in the last two years.
