GCSE results for England, Wales and Northern Ireland have shown a sharp decline, with the proportion of A*-C grades dropping 2.1 per cent compared to last year.
A drop in pupils achieving a C or above was predicted before the results were released, due to the new policy that requires 17 year-olds to re-sit English and Maths if they got a D or lower the first time around.
Of the older pupils retaking exams, fewer than a third achieved a C or above, compared to 70 per cent of 16 year-olds taking the exams for the first time.
However, while the number of resits impacted the large fall in grades, the proportion of first time entries gaining A*-C was still down by 1.3 per cent compared to 2015.
The number of students achieving top grades also fell for the fifth year in a row, with the proportion gaining A or A* dropping 0.7 per cent to 20.5 per cent.
English and Maths saw some of the largest falls, with the proportion of pupils gaining A*-C in English falling 5.2 per cent to 60.2 per cent and maths dropping 2.3 percentage points.
Skills England has announced that development of the second round of Local Skills Improvement Plans (LSIPs) is now underway and has published guidance to steer the process
