Birmingham City Council is considering legal action in the wake of the GCSE fiasco.
The authority said it was “looking into” the possibility of a challenge after scores of students received lower than expected English grades in their exams.
The council could join councils, schools and teaching unions across the country demanding a re-think after exam regulator Ofqual’s refused to re-grade GCSE English papers in England.
Schools nationwide raised concerns that papers had been marked too harshly, with heads reporting an unprecedented number of fails.
Ofqual admitted the grade boundaries were higher in June than in January but has so far refused to bow to calls for the exams to be regraded.
Birmingham Council education chief Coun Brigid Jones said: “We are looking into this and we are talking to schools to establish the best way forward.”
Among the city schools hit by lower grades was Golden Hillock in Sparkbrook, where 50 parents and pupils staged a protest demanding answers.
The dip in English grades at the school meant it posted one of the city’s lowest overall set of GCSE results, with 39 per cent of students achieving the Government benchmark of five or more GCSEs at grades A* to C, including maths and English.
An alliance of 180 pupils, 36 local authorities and seven professional organisations have so far joined forces to challenge Ofqual and the examination boards over the row.
They want the affected exams regraded, or face a High Court claim for a judicial review.
Brian Lightman, general secretary of the Association of School and College Leaders, which is part of the alliance, said: “This legal challenge is essentially about fairness.
“Young people only have one chance at a good education and it is wrong that 16-year-olds are paying for mistakes made by adults who should know better.
“This is about putting right the errors made by Ofqual and the awarding bodies in this year’s exams.”
