Abstract:

Randomised controlled trials (RCTs) are the gold standard for evaluating educational interventions. However, Ireland is approximately 20 years behind the US and 10 years behind the UK in implementing randomised controlled trials in education. This paper examines the role of RCTs in advancing educational research in Ireland, building on a recent commentary by Gilleece and Clerkin (2024. “Towards More Robust Evaluation of Policies and Programmes in Education: Identifying Challenges in Evaluating DEIS and Reading Recovery.” Irish Educational Studies). It explores the fundamental characteristics of RCTs, including randomisation, the use of control groups, blinding (or masking), sampling, power and analytical considerations. Additionally, the paper discusses other key aspects such as process evaluations, economic evaluations, ethical issues, and the importance of transparency in conducting RCTs. Selected examples of RCTs conducted in Ireland are presented to make the discussion directly relevant to the Irish context. RCTs are an essential tool for evidence-informed educational policy and practice and, where appropriate and feasible, can be used to address key national issues such as the Literacy, Numeracy, and Digital Literacy Strategy (2024-2033) implementation plan and the use of AI in education. We hope that this paper will serve as a practical guide for policymakers, researchers, and educators and will stimulate further discussion on RCTs in Irish education.
