In educational research, the complexity of interventions and the diversity of contexts challenge the adequacy of existing reporting standards, primarily tailored for health interventions and randomised controlled trials. Recognising the critical need for appropriate tools to support education research, we developed two checklists: the CheckList Of Standards of reporting in Education Research (CLOSER) and the Checklist for Intervention Description of Education Research (CIDER). CLOSER was designed to guide the comprehensive reporting of quantitative educational intervention research from the abstract to the discussion for multiple study designs. Concurrently, CIDER details the precise features of educational interventions. The final refinements of CLOSER and CIDER comprise of 34 and 17 items, respectively, developed through a five-stage process, including tool adaptation, expert feedback, a 2-round modified Delphi consensus survey, and final refinements. These checklists aim to enhance the clarity of educational intervention research findings, facilitating their replicability and subsequent meaningful translation into practice and policy. This addresses the gap in educational research reporting standards and sets the stage for a more robust, evidence-informed approach to educational intervention development and evaluation.
