IES Breckland were not available for interview regarding Mick Smith's criticism, but referred ITV News to a previous statement by the Principal Alison Tilbrook regarding Ofsted's decision to place the school in special measures.
"We are of course dissatisfied with our performance in the recent Ofsted inspection but accept the team’s conclusions and we are already taking steps to address many of the issues identified in the report.
"This inspection came in the middle of a process of change at IES Breckland, following our own assessment of the school at the start of the academic year, and we have already taken steps to strengthen the leadership and teaching staff. A new full-time Principal has taken up post and a number of new staff at all levels have either recently started or are due to do so shortly.
"While there is still a long way to go, the report recognises that 'IES has acted promptly to appoint a new Principal and other managers' and that 'school leaders have begun to tackle some of the weaknesses identified by inspectors'.
"The changes we have made are showing improvement and we know that the school is moving in the right direction. The teachers and staff at IES Breckland are committed to providing a higher quality of education to students and will continue to work to improve standards at IES Breckland.
"We look forward to future Ofsted monitoring visits and inspections showing the direction in which we are moving."
