The Effect of Group‐level Influences on Pupils' Progress in Reading

This article investigates the existence or otherwise of group‐level effects on progress in reading. ‘Administrative’ data, i.e. data already produced by a local education authority (LEA) for its own purposes, was combined to give two primary‐age cohorts, each of the order of 2500 pupils, in one medium‐sized LEA in the south‐east of England. After allowing for pupil and global school‐level effects, a wide variety of possible aggregated group‐level effects (AGLEs) was investigated. Different functions of pupil score were investigated. Mean score and pupil turnover, especially the latter, were the most important AGLEs on attainment, and these had greater effects for older pupils.
