Leaders of the other largest teachers' unions, the NASUWT, will meet on February 14 to consider calling industrial action.
General secretary Chris Keates said "The Secretary of State [for Education] must understand that the teaching profession is on the verge of a crisis."
The general secretary of the National Union of Teachers (NUT), Christine Blower, has blamed the forthcoming strike action on the "intransigent" Education Secretary Michael Gove.
She said the two main teaching unions - NUT and NASUWT - met Mr Gove 17 weeks ago, but that there has been no progress since then.

President of the Wales Trade Union Congress (TUC) has heavily criticised the UK Government over cuts to public sector workers pensions.
Stephanie Wilkins has worked as a bio medical scientist for the NHS for over twenty years.
She claims she has been forced to join fellow NHS workers, and others from across the public sector, on the picket line in sending a message to the UK Government.
Like all those taking part in this 24 hour strike Stephanie says she doesn't want to pay more to work longer and get less.
The changes will mean that she will be £30 a month or £1,400 a year worse off.
NHS staff from across Wales have formed picket lines outside hospitals today as part of a 24 hour strike over UK Government planned changes to their pensions.
