Mathematics in Education and Industry (MEI)

MEI is committed to improving mathematics education and promotes teaching and learning through different strands of activity. We support teachers through a range of professional development opportunities, including our annual conference. Innovative resources are continually being developed to extend and enrich your knowledge of mathematics, whether teacher, student, undergraduate or member of the workforce.

MEI takes various opportunities to share and discuss with you the changing landscape of mathematics education, including consultation, discussions, social media, and our newsletters. Another way you can get involved is through our membership scheme. Our local branches for Members and Educational Associates provide professional development as well as a forum for discussion.

MEI is an independent charity; any income generated through our work is used to support mathematics education. We are a partner in the NCETM consortium, and also manage the government-funded Advanced Mathematics Support Programme.
