Last year's national curriculum tests cost the taxpayer pound;24.3 million, schools minister Jacqui Smith has revealed.
In response to a question from the Liberal Democrat MP Norman Baker, Mrs Smith declared that the average cost of each test was pound;5.30 per pupil per subject.
The figure covers the coss of developing, printing and distributing test papers across key stages 1 to 3.
It also includes the cost of external marking and data collection at key stage 2 and 3. However, costs of supply cover for teachers and administration expenses incurred by schools are excluded from the figure.
