Education Secretary Michael Gove stunned contractors by axing rebuilding and refurbishment plans for more than 700 schools.
Now leaders of teaching union NASUWT are organising a lobby of Parliament on Monday July 19 to protest against the move.
General Secretary Chris Keates said: “Pupils, parents and school staff across the country are reeling from the devastating news of their school building programmes being slashed.
“Cutting the school building projects is totally unnecessary and is jeopardising the educational future of many children and young people.
“The NASUWT believes that it is time for schools and parents to voice their concern to members of Parliament.”
Keates has now written to the 715 schools dumped from the BSF programme by Gove asking them to join the March on Westminster.
The letter states: “We believe that as a result of the massive cuts to funding to improve school buildings, tens of thousands of pupils are being condemned to learn in dilapidated school buildings which are simply not conducive to educational excellence.”
“The Government’s decision to cut funding for school building improvement needs to be reversed. The educational prospects of thousands of children, young people and communities depend on it.”
