Abstract
Recent work on classroom and school effects in Australia has suggested that teacher effects
account for up to 50 per cent of variation in mathematics achievement. The present study used
data from the Third International Mathematics and Science Study (TIMSS) to look at
classroom and school differences in mathematics achievement at both primary and secondary
school levels. It found that while, classroom differences account for about one-quarter of the
variation in student achievement, little of this was due to teachers. Most of the classroom
variation was due to compositional and organisational factors. This has important implications
for policy regarding the improvement of mathematics achievement in schools.
