At least 17 school leaders across England received pay packets worth more than £150,000 last year, a new analysis of figures shows.
This includes the packages of seven head teachers outside London, all earning more than the Prime Minister, which have just been discovered.
The disclosure comes days after it was revealed that a London primary school head is being paid £270,000.
Mark Elms, head of Tidemill Primary School in south-east London, was given a remuneration package of £276,523 for 2009-10 including employers' pension, according to an analysis of Lewisham Council's accounts.
Further investigation of local authority accounts in England, conducted by the GMB union, shows that more are receiving bumper pay packets. A school employee in Essex received between £230,000 and £234,999 in 2009-10, although no further details were given, so it is not known how much of this was salary.
John King, head of both Gable Hall and William Edwards schools in Thurrock, Essex, received a salary package worth £155,891, which rose to £177,872 including pension contributions. The cost was split between the two schools.
Kelvin Simmonds, head of Danum School in Doncaster, received a package worth £152,224, which rose to £173,999 with pension contribution.
It was revealed this week that 11 head teachers in the capital, including Mr Elms, receive more than £150,000 – above the PM's £142,500 salary. Many more are thought to be earning over £100,000.
