The ballots are being held in response to calls from members in those areas and schools who are suffering excessive workloads as a result of the shortages. (Attached is a list of areas where ballots are going on.)
The ballots are being conducted by the Electoral Reform Society Balloting Services. The results will be known shortly after the close of voting and action will begin as soon as possible after that date.
Commenting, Doug McAvoy, NUT General Secretary, said: 'In addition to around a thousand schools in London where action will begin on March 12, our members from Liverpool to Southampton are feeling the impact of the shortages.
'It is the failure of successive Government's which has created this situation. It is their refusal to recognise the problem which has caused the pressure for action from our members. They are tired of being exploited and of their commitment to their pupils being taken for granted. They are no longer willing to cover up the failure of governments to ensure there are sufficient teachers to educate our children.
'The Government's claim that only a handful of schools have problems of unfilled vacancies is shown to be false by the increasing number of teachers seeking protection.'
Ballots are completed for all London boroughs and Doncaster. Ballots in eight other areas have previously been announced.
Nine further areas have been added as marked below.
No date can yet be given for when the results of the ballot will be known. In each case it will be soon after the ballot closes but the exact timing is determined by Electoral Reform Balloting Services.
