In this work, data from educational trials funded by the Education<br/>Endowment Foundation (EEF) were linked with follow-up data from the National Pupil Database in order to enable an analysis of the longitudinal effect of<br/>educational interventions. The analyses used carefully parameterized multilevel<br/>models with three levels for time, pupils, and schools, enabling a comprehensive<br/>understanding of educational trajectories and their temporal dynamics.
