There are dangers in the chief inspector's suggestion of 'parachuting' top teachers into struggling schools, says union official Nansi Ellis
Some secondary school teachers were guilty of "significantly" over-marking pupils' GCSE English work in a bid to boost results, Ofqual said.
Trainee teachers are set to face more difficult tests in English and maths before they are allowed to start training in the profession.
The two largest teachers' unions in England and Wales are to outline plans for strike action later today.
In July, the NUT and NASUWT unions announced they would hold a one-day national strike, as well as rolling regional strikes in September and October. They have not stated the exact dates of the strikes.
Both unions are in a dispute with the government over pay, conditions and pensions.
Teachers are to stage a one-day national walkout in the autumn in a continuing row over pay, pensions and workload, the NASUWT and the National Union of Teachers announced.
Ofsted's chief inspector Sir Michael Wilshaw has reiterated his call for so-called "National Service" teachers to help raise standards in struggling schools across the country.
Speaking on ITV News, he said this approach - where top headteachers and teachers drive up standards - had been successful in London and other large cities:
Greg Wallace, the head of the Best Start Federation which has turned around five failing schools, has said he welcomes the idea of top teachers being parachuted into struggling schools.
Asked whether "hot shot" teachers from city schools could understand the problems of a rural school, he said: "Why not? ... Children are children and they're more similar than they are different."
The country’s most talented teachers should be parachuted into schools that are failing disadvantaged pupils, Chief Schools Inspector Sir Michael Wilshaw will urge today.
Louise Bennett, headteacher at The West Grantham Academy St Hugh’s, told Daybreak: "Schools need to learn from each other.
"What we do here is we try and look really carefully at what we do well and we try and share with other schools and we're alread got teachers who are working in other schools."
Brian Lightman, general secretary of the Association of School and College Leaders (ASCL) said:
While there is no excuse for complacency, you have to take into account how many rural and coastal schools are funded compared to inner city schools.
In the last decade, the intense focus has been on raising achievement in inner city schools, both in support and funding through the London and City Challenges.
The Pupil Premium has helped to address the funding gap to a certain extent but overall there is still a huge inequity in funding.
Schools in poorly funded authorities have less money to attract excellent teachers in key subjects, to buy in additional support and to reduce class sizes and teaching loads.
A Department for Education spokesman said they would consider Ofsted recommendations and respond in due course.
Ofsted's chief inspector has said that pupils are being let down in leafy suburbs, market towns and seaside resorts rather than the inner-city schools:
Today, many of the disadvantaged children performing least well in school can be found in leafy suburbs, market towns or seaside resorts.
Often they are spread thinly, as an 'invisible minority' across areas that are relatively affluent.
These poor, unseen children can be found in mediocre schools the length and breadth of our country. They are labelled, buried in lower sets, consigned as often as not to indifferent teaching. They coast through education until - at the earliest opportunity - they sever their ties with it.
– Sir Michael Wilshaw, Ofsted chief inspector
The most important factor in reversing these trends is to attract and incentivise the best people to the leadership of underperforming schools in these areas.
This may require government to work with Teaching Schools to identify and incentivise experienced and effective teachers to work in less fashionable, more remote or challenging places. The concept of a 'National Service Teacher' should be considered.
In a speech, Sir Michael warns that there is an "invisible minority" of disadvantaged children living in "leafy suburbs, market towns or seaside resorts" who are being let down by their schools.
These youngsters are under-performing and coasting through school until they leave at the earliest opportunity.
The quality of education is the most important issue facing Britain today. In the long term, our success as a nation - our prosperity, our security, our society - depends on how well we raise and educate our young people across the social spectrum.
An army of top teachers should be deployed in schools that are failing their poorest pupils, Ofsted's chief inspector will argue in a speech today.
Sir Michael Wilshaw is calling for the Government to recruit a proportion of England's most talented teachers to teach in "less fashionable, more remote or challenging places".
Teachers could be offered incentives to sign up to become a National Service Teacher such as bigger pay packets, higher status and faster career progression.
