According to research, around 400,000 schoolchildren in Britain are being taught by unqualified teachers, based on a class size average of 25.3.
In 2012, former education secretary Michael Gove introduced the right for free schools and academies to use unqualified teachers.
But since taking the stand as Labour's shadow education secretary, Tristam Hunt has highlighted the extent to which state-funded schools are using unqualified teachers and as a result, made it his central campaign to put a stop to it.
Mr Hunt revealed that the number of unqualified teachers in state schools increased by 16 per cent to 17,100 over the past 12 months, rising by 50 per cent to 7,900 since Mr Gove's legislation in 2012.
He said: "David Cameron's decision to allow unqualified teachers to be permanently employed in schools is seriously threatening standards for hundreds of thousands of children - and the figures are rising."
"Labour will reverse the unqualified teachers policy and put teaching standards first, with our ambition of a world-class teacher in every classroom.
"We will ensure that all teachers become properly qualified, continue to build their skills and are able to pursue new career pathways that keep the best teachers in the classrooms."
Mr Hunt remains adamant that a Labour government would go to great lengths to ensure all permanently employed teachers were qualified.
This would bode well for children with special educational needs who require additional support - both in and outside the classroom - through methods such as assistive technologies.
If schools employ more teachers who have the necessary training, it's likely that they will be better equipped to help such children, in turn contributing to their academic growth.
