DSG allocations for 2007-08 are based on pupil numbers from the January pupil counts and a single guaranteed unit of funding per full-time equivalent pupil aged three to 15 (as announced December 2005). These can be found at http://www.teachernet.gov.uk/docbank/index.cfm?id=9405 and a copy has been placed in the House Library.
There is no separate guaranteed unit of funding for primary and secondary schools.
