"In 2016, I became a cohort 1 Secondary Mastery Specialist through the NCETM programme. As part of my role I was given the opportunity to apply for the England-China Mathematics teacher Exchange. The two-week trip consisted of one day at Shanghai Normal University with a welcome ceremony and a lecture by Professor Gu followed by three days in a secondary school and one day in a primary school each week, as well as a lecture on the middle Sunday. It was an amazing opportunity to observe in practice the inspiration behind the principles of Teaching for Mastery and learn about the Shanghai education system and culture."
