To ask the Secretary of State for Education what recent estimate his Department has made of the proportion of schools which offer split sciences at GCSE level.

The Department does not hold information on the subjects offered by schools but does have data on the subjects that pupils were entered for. Data underlying the School Performance Tables show that 85% of mainstream schools had entries in biology, chemistry and physics GCSEs or regulated IGCSEs by pupils at the end of Key Stage 4 in 2011/12. Only mainstream schools (including independent schools) published in the 2012 Secondary School Performance Tables having more than five pupils at the end of Key Stage 4 are included in this answer.
