PROGRAMME FOR INTERNATIONAL STUDENT ASSESSMENT 2000 - SCOTLAND ANALYSIS

SECTION 6 - SCHOOL STAFF AND RESOURCES

School Size

1. Because of the large number of influences upon every pupil, no single factor can be expected to explain any large part of the variation in performance. The number of pupils in a school does not appear to have any significant correlation with test scores of Scottish pupils. However, in the UK as a whole there is a very small, but significant, effect that pupils in large schools perform worse than those in smaller ones. This effect in the UK is much larger when the number of pupils per teacher is considered, accounting for 1.7 per cent of variation in test scores. Pupils in schools with a large number of pupils for each teacher tend to perform considerably worse than those with fewer pupils per teacher. In Scotland, the effect is again not significant.

2. In Scotland, however, a significant relationship is noted between reading test score and the number of computers per pupil. This accounts for 0.5 per cent of the variation between pupils' scores.
