Academic Advisory Board

The Academic Advisory Board, under the leadership of Dame Erica Pienaar, carries out many of the functions traditionally associated with a governing body. It operates as a critical friend to the headteacher and his team, providing advice, monitoring the quality of education and offering challenge.
Dame Erica has had a long and distinguished career in education and was appointed a Dame for her services to education in the 2014 Queen’s birthday honours list. Until 2013, she was Executive Head Teacher of the Leathersellers’ Federation of Schools. The federation comprises three Colleges: Prendergast-Hilly Fields College, Prendergast-Ladywell Fields College and Prendergast-Vale College. The federation is a “hard federation” led by a single governing body.
