This case report presents the findings of an Irish Research Council (IRC) funded research project carried out by the University of Limerick and Dublin City University between November 2014 and May 2016. It is an explanatory single case study that examined the phenomenon of a whole school approach to guidance counselling (personal and social, educational and career) in one Irish voluntary post primary school since the re-allocation of guidance counselling provision in Budget 2012. The case study is set against the backdrop of national and international policy, practice and research in guidance counselling that proposes new types of delivery models and integrative approaches to meet the needs of young people and adults in an increasingly complex and uncertain world. It has also been conducted during a period of ongoing policy changes in post primary education and guidance counselling that point to a partial restoration of the guidance allocation in September 2016, and potential developments in the long-term (DES, 2016b,c).
