More than a third of 16-year-olds in Newham failed to pass both their English and maths GCSEs this year.
Department for Education figures show that 35 per cent of pupils sitting their exams this summer didn’t reach the required passing grade in the two core subjects.
GCSE's are a fundamental requirement for colleges, sixth forms and schools that students resit these qualifications if they do not have a grade 4 (or C) already.
Those 1,297 students are now facing compulsory resits in June 2019.
A total of 3,749 students took their GCSEs this year. Most of the exams are now graded on a 1-9 scale under the new system.
A pass grade, previously a C, is now a 4 and a 9 is reflecting the need for a grade higher than the previous A*.
The government has defined a grade 5 as a strong pass, which would fall between a B and a C in the old system.
Girls in Newham were more successful than boys, with 68% of girls achieving a grade 4 or above in English and maths compared with 63% of boys.
At grade 5 and above, with 48% of girls getting a strong pass compared with 44% of boys.
