The Pioneer Academy Trust was formed when Stewart Fleming Primary School became an academy in 2011.  In May 2012, The Trust was asked by Bexley Local Authority to support Belvedere Junior School which then converted to an academy in April 2013.  The Trustees were once again approached by Bexley in the summer term of 2014 to support Burnt Oak Junior School which subsequently converted to an academy in July 2015.

Since then, more schools have joined the Pioneer Academy and there are 15 schools in total that make up the Trust.
