Despite his prolonged absence, the school had continued to thrive under the care of interim head Hannele Reece and the rest of the school leaders and staff, the governors said.
“At this critical time of year, with many students about to take important public examinations, we remain assured that, thanks to the experienced, committed and hard-working leadership and staff, all our students have been able to enjoy a stable, calm and productive learning environment this academic year,” they said.
Mr Slater arrived after a period of uncertainty at the top of the school. In 2014 the headteacher Jo Shuter was forced to leave after only a year after being banned from teaching because of financial allegations relating to a previous school. KKSHS was run by a temporary head for a year.
In 2016, the year after Mr Slater’s appointment, it received a good Ofsted report.
