ABSTRACT
Ask yourself this question. How is it that some effective primary schools continue to have an impact on pupil achievement when they are 16? Sammons (1993) found that pupils who attended particular primary schools in the School Matters Project (Mortimore et al., 1988), were likely to achieve at 16 significantly better results than they would had they attended less effective primary schools-whatever their prior attainment, gender, ethnic or cultural background, and whatever secondary schooling they experienced.
