The Welsh Government has pledged to find out urgently why thousand of pupils across Wales have performed poorly in recent exams.
It comes after a big fall in grades for a pioneering English Language GCSE.
37,000 pupils sat the exams in January, and have been getting their results this week.
Schools across the country say youngsters got much poorer grades than expected in the first such GCSE especially designed for schools in Wales - but there are worries tonight that the results may actually reflect poor levels of literacy in our schools.
The former head of an Anglesey primary school found guilty of unacceptable professional conduct by a hearing has been baned from working as a headteacher in Wales.
The General Teaching Council for Wales tribunal ruled that Ann Hughes would be allowed to work in other management roles.
The Welsh Government says it is investigating unexpectedly low GCSE English language exam results "as a matter of urgency."
Education Minister Huw Lewis announced this afternoon that he has ordered a "rapid fact-finding exercise... to establish what are the key issues underlying the results" and look at how to support schools for future entries.
He said the investigation will initially report back by the end of this month.
However, Huw Lewis said planned changes to GCSEs will still go ahead: "we are committed to our reform programme to increase rigour in the qualifications system in Wales."
A former headteacher on Anglesey had been found guilty of unacceptable professional conduct.
However, an allegation that Ann Hughes was excessive in inviting a police officer to reprimand pupils when they did not pose for a school photograph was not proven.
Mrs Hughes faced eight allegations at a General Teaching Council for Wales hearing in Flintshire.
Two accusations - that she failed to maintain a co-operative working relationship between staff, and failed to ensure effective communication within the school - were judged to be proven against her by the panel.
Two other accusations - that she failed to properly investigate incidents of bullying, and failed to ensure with parents effectively - were judged to be partly proven.
Four further accusations were not proven, the panel ruled.
The Welsh Government insists it is "on track" to deliver planned reforms to GCSE qualifications next year, after a call from the WJEC exam board that new courses should be delayed.
It plans to introduce new GCSE courses in English, Welsh, maths and the Welsh baccalaureate, in September 2015.
Gareth Pierce, Chief Executive of the WJEC, warned schools may not be ready for changes, after concerns were raised about unexpectedly low grades for GCSE language exams sat by pupils in January, following changes to that subject.
– Welsh Government spokesperson
We will be working with WJEC and schools over the next few weeks to establish the issues that may have affected the results achieved by students in the units sat this January.
Following the independent review of qualifications we have established an extensive reform programme to transform qualifications in Wales – to improve rigour and raise standards – we remain on track to deliver our reforms.
Teachers unions are calling for an investigation into the low results achieved by youngsters in a pioneering exam in core English Language skills.
The GCSE was designed specifically for schools in Wales after a previous row over exam results. But it's seen the number of candidates getting grade C in one section fall dramatically.
Plaid Cymru has raised the prospect of full time education for all children from the age of three
The idea would be part of a package that could cost £300m. But where would the cash come from?
Mike Griffiths reports.
Our members are concerned that the results released yesterday have not
matched the expectations of experienced teachers. In many, though not all
cases, grades are lower than expected and this may indicate that there are
information issues surrounding the roll-out of the new award.
One of the traditional strengths of the Welsh system is that the WJEC
has in the past worked closely with schools to ensure that teachers know
what is expected of their pupils. It is therefore doubly disappointing when
communication goes wrong. We urge the WJEC to release the mark scheme
as soon as possible so that teachers can get to the bottom of what has
happened and put things right in time for the summer examinations. If it
cannot be put right, these results should not stand.
– NAHT Cymru Acting Director, Dr. Chris Howard
These results are not yet set in stone. Good communication between the
board and schools might rescue the situation and help restore trust in the
system. If teachers can’t explain what has happened, how can we expect
pupils and parents to feel confident about the new Welsh examination
The exam board for Wales, WJEC, says the results of a new exam for GCSE English has led to a sharp drop in pupils achieving a Grade C - from 23% to just 5%.
In January pupils sat for the first time units developed in response to Welsh Government's requirements.
Greater emphasis is placed on accuracy of sentence structure, punctuation and spelling in the writing sections and accuracy for 50% of available marks whereas previously it was 30%.
The exam body says examiners have noted that while there were fewer examples of candidates not completing the papers, it was clear that some candidates were not producing fully developed responses to the written questions.
Examiners also expressed their concerns that candidates had found the new accuracy and comparison requirements on the paper particularly challenging says the WJEC.
We are aware that GCSE English Language unit outcomes from January 2014 are lower than unit outcomes from January 2013. However, it is misleading to try to make direct comparisons between units as the new specification is structured differently to the previous specification.
– Welsh Government Spokesperson
Also, the entry for January 2014 was much higher than for January 2013, with schools deciding to enter a greater proportion of learners before the end of the course. What is important is the overall outcome when learners cash-in their GCSE English Language results in the summer.
