The National Association of Head Teachers (NAHT) has welcomed a report by Carol Vorderman which has called for the Key Stage 2 maths test to be abolished.
According to the report entitled 'A world class education for all our young people' produced by Task force, roughly half of all pupils do not achieve Grade C or above in GCSE mathematics.
By focusing their lessons on the test for at least two terms this can result in students actually having a diminished mathematical understanding, the report finds.
Kathryn James, director of policy and campaigns at the NAHT, said the association agreed strongly with the findings.
"Ms Vorderman acknowledges that the existing quality of teaching is not the issue. Rather it is the constraints placed on schools to deliver results which make easy headlines but which do little to help children learn, that is the problem."
The Association of Teachers and Lecturers also voiced its agreement, saying that it is every child's basic right to be able to study mathematics to a certain level.
