State schools have seen immense improvements in recent years and could even cause some private schools to go out of business, according to the Good Schools Guide.
The guide was first published in 1986, at which point it recommended just ten state schools, which equalled four per cent of its total. 30 years later this number has surged to 300, which is 25 per cent of the schools in the state sector.
Lord Lucas, editor of the Good Schools Guide, said that the featured schools were chosen by parents who were more interested in sending their children to state schools now than in the past.
Published annually, the guide contains portraits of some 1,200 schools, mostly written and chosen by parents, including schools which do not necessarily get good results but do benefit children.
A body which represents private schools has spoken of the positivity of such improvement to state schools.
In line with the guide, a Department for Education spokesperson said that 1.4 million more pupils are now being taught in schools rated as "good" or "outstanding" by Ofsted than in 2010.
"Our reforms have been underpinned by a commitment to social justice and fairness - that means achieving educational excellence for everyone, everywhere, regardless of their background," he added.
The Headmasters' and Headmistresses' Conference (HMC), which represents nearly 300 independent schools, said it was "good to see education for all pupils improving" and attributed some of the success to partnerships with independent schools.
HMC's chairman Christopher King said it was an "ongoing challenge" to provide future-proof education for children "at a fee parents can afford".
According to the Independent Schools Council, 517,113 pupils were at UK independent schools last May, which is the highest level since records began 40 years ago.
