Nearly half of Cornish primaries inspected 'not good'
Nearly half of the primary schools inspected by Ofsted in Cornwall since February have been judged as requiring improvement or inadequate.
Ten of the 25 schools inspected required improvement, two were deemed to be failing and 13 were good.
In February changes were made to Ofsted's inspection regime, with the "satisfactory" verdict replaced with "requiring improvement".
Ofsted admitted its inspections had been "made harder".
The research was compiled by BBC Radio Cornwall.
Small village school
Paul Hayes, the head teacher of Mabe Primary School, in Penryn, which has moved from outstanding to requiring improvement, said: "I recognise that there are areas where we need to improve.
"But if you speak to the parents and wider community they don't feel we failed Ofsted, they think this is a good school."
Mr Hayes said just three or four pupils had affected the results at the school because it was a small village one.
He also said the Ofsted report relied too much on data about pupils' achievements.
Ofsted said the inspection regime "has been made harder because every child deserves a good education".
A spokesman said: "Outstanding schools are encouraged to work with schools in need of improvement so that the education levels rise for everyone."
Ian Bruce, the Cornwall representative for the National Association of Head Teachers, said: "In the last 12 months the Ofsted regime has changed three times.
"It's important for inspectors to look at all aspects of school life."
