Secondary Checkpoint assessments are taken by students at the end of the Cambridge Lower Secondary programme (aged 14) in countries around the world. Many students continue with Cambridge after this and take IGCSE exams two years later. Given that there is a high level of coherence between the curricula in the two stages, performance in Secondary Checkpoint should be a good indicator of performance at IGCSE. In this article, I investigate whether there is evidence to support this contention, by calculating correlations between Checkpoint scores and IGCSE grades, across a range of subjects. I also look at whether students in schools offering the Cambridge Lower Secondary programme go on to perform better at IGCSE than schools not offering the programme.
