The need for an ecumenical Christian secondary school in Brighton and Hove was identified by local parents who wanted their children to have a secondary education which built upon the high quality education their children had experienced at the popular local Christian primary schools.
In September 2011, the founding parent group asked the school standards specialists and academy sponsor, the Russell Education Trust (RET), to work alongside them to set up and run the school. They applied to the Department for Education for the funding of a Free School in February 2012, were shortlisted for interview in May 2012 and received news of their success in July 2012.
RET and local parents formed a Steering Group, which was led by RET. The Steering Group appointed the Founding Headteacher, Steve Flavin, with the support of the Chichester Diocese, in February 2013. In May 2013, the rest of the founding staff were appointed.
King's School opened its doors to its first cohort of Year 7 students on Wednesday September 4th 2013.
