One of the country's 'leading free schools' is looking for its third headteacher in three years.
Former England hockey coach Sam Naismith only stepped into the role from deputy headteacher at the beginning of 2013 when the previous head Thomas Packer left after two years.
The secondary school in Hammersmith, set up by journalist Toby Young was opened by Mayor of London Boris Johnson in 2011 to much acclaim as it was the first secondary free school in London.
It claims it has 10 applicants for every one of its 360 places, making it the most over-subscribed state secondary in Hammersmith and Fulham but parents are not happy with the high staff turnover following an advertisement for a new headteacher in the Times Educational Supplement.
The job advertisement said the school is seeking a candidate to 'be the public face of one of the country's leading free schools' and that the school's motto, Dare to Learn 'will apply to the head as well as the pupils'. It also offered a salary 'to attract the best'.
A parent writing on leading website Mumsnet, said: "The staff turnover is very high. I'm rather astonished at the rate teachers come and go. I imagine they're still trying to establish a very strong team of staff and this takes time.
"Still, it's unsettling. Should I be more patient with this rather new school and new concept which I initially was very supportive of? Little red flags are waving and I am trying to ignore them."
Parents subscribing to the Good Schools Guide online were told that Mr Naismith left abruptly in May 2014 but the school's website still has him as the headteacher.
The website is also advertising for a science teacher and a classics teacher.
The West London Free Primary in Bradmore Park Road, Hammersmith opened in September 2013 and another school called the Earls Court Free School Primary, run by the charitable trust, was given the green light in November last year by the Department for Education to open in September 2014.
Getwestlondon is waiting for a comment from Toby Young and the school.
