Ofsted inspectors rely too heavily on exam and test results when forming their verdict on schools, the head of one of England’s big three exam boards claimed this week. Greg Watson, OCR chief executive, warned that the trend could have a distorting effect on the exam system and teachers’ behaviour, and said a broader view of school performance should be taken. He also repeated the view of OCR parent company Cambridge Assessment that there was a lack of public trust in the assessment system. He said he was concerned that some schools were putting too much pressure on pupils to opt for Diplomas.
