[Schools are spending tens
of thousands of pounds more a year to
meet rising costs of contracts with private firms.
These Private Finance Initiative (PFI) schools
are locked into 25- to 30-year contracts
in which charges rise more than at
other schools.
One school said it was spending thousands
of pounds a year to keep its playing-field grass
below 2.5cm (1in), as the "rigid"
contract demanded.
PFI investors say the contracts give long-term
value for taxpayers' money.]
