Plans to scrap GCSEs in key subjects in England and replace them with English Baccalaureate Certificates are being abandoned by the government.

The reversal was announced by the education secretary in the Commons, alongside curriculum changes.

Michael Gove said plans for the new exams had been "a bridge too far".

He had wanted to bring in what he said were more rigorous exams in some core subjects from 2015, but faced criticism from MPs and teachers.

Labour's shadow education secretary Stephen Twigg told MPs the announcement was a "humiliating climb-down" and exam policy a "total shambles".

The change means plans for the new qualification, announced in September, are being shelved, while GCSEs are retained, despite having been previously condemned by the education secretary.

The reversal has refocused the spotlight on the future form of GCSEs .

Grade inflation

It comes after a damning report by the Commons education committee which said the changes would mean "too much, too fast" and could threaten exam quality.

The new English Baccalaureate Certificate was billed by the government as having a tougher syllabus, with exams at the end of the course in a return to an O-level style traditional qualification.

Mr Gove told MPs: "Last September we outlined plans for changes to GCSE qualifications designed to address the grade inflation, dumbing down and loss of rigour in those examinations.

"We have consulted on those proposals and there is now a consensus that the system needs to change.

"But one of the proposals I put forward was a bridge too far."

Specifically, he said that proposal had been to let just one exam board set a GCSE for each English Baccalaureate Certificate. The idea behind this was to stop what he had called a "race to the bottom" where he said exam boards might compete to offer easier qualifications.

However, he also re-stated his belief in changes already being made to GCSEs, where there has been a switch to exams being taken at the end of two years rather than in stages, fewer re-sits and a reduced role for coursework.

And he said a tougher GCSE in some key subjects would come in from autumn 2015.

Liberal Democrats had opposed the introduction of the English Baccalaureate Certificate, believing they would bring in a two-tier system, which would damage teenagers who were not academic enough to pass the new exams.

A senior Whitehall source told the BBC's political editor Nick Robinson a range of factors conspired to bring an end to the plans, including opposition from the regulator and concerns that introducing a single exam board for each subject could be challenged in the courts under European Union rules.

Lib Dem sources indicated they regarded this as a coalition decision not a policy victory for their party, our correspondent added.

In the Commons, Labour's Stephen Twigg said: "It's simple really, before he announces a bright idea wouldn't it be sensible to check it first with the deputy prime minister".
'Red light'

The proposals for the new qualifications were met by intense criticism from teaching unions when they were first floated last June and then set out in detail in September.

The original plan had been for the first candidates to start courses in 2015 and take the new-look exams two years later, initially in three core subject areas - English, maths and sciences - with an extension later to history, geography and languages.
