Dr Rachel Marks is passionate about education and in particular the hope that all children can have a fair and equitable opportunity to be taught the best, by the best. She believes that every child – of every age – has the right to receive an inspiring, holistic education that allows them to ‘dream big’ and to know they can achieve. To this end, she campaigns tirelessly against segregated educational practices, publishing and presenting to a wide range of audiences, face-to-face and online, and serving on a range of editorial and executive boards, to challenge some of the persistent and often stigmatising practices currently underpinning the English education system. Her book – Ability Grouping in Primary Schools: Case studies and Critical Debates – continues to attract both positive reviews and robust scrutiny from multiple audiences, some of whom may feel challenged by the ideas asserted in the book and the apparent challenge to the status quo. Rachel certainly isn’t afraid to provoke debate.
