The Association of Teachers and Lecturers have attacked the "haste" with which the Education secretary Michael Gove is proceeding with plans to overhaul GCSEs.
The teaching union said first year secondary school pupils were going to be "Mr Gove's guinea pigs".
We want all children to succeed in education, and we need exams that are rigorous. However, the haste with which Michael Gove is pushing through huge simultaneous changes to both exams and the curriculum carries major risks that will put last summer's English GCSE debacle into the shade.
"We particularly feel for the children in their first year of secondary school who are going to be Mr Gove's guinea pigs. They will have a single year being taught the new curriculum when they are 13 and then move straight into the new and untested GCSE exam syllabus at age 14."
On his third attempt, Michael Gove has unveiled plans to shake-up the current exam process for assessing 16 year olds in England.
As the government outlines changes to the GCSE system, we take a look at current maths exam papers. How well did you do?
