The NCETM Professional Development Lead Accreditation is designed for those who lead professional development for teachers of mathematics. There is a choice from five possible pathways to accreditation depending on the phases of the teachers with whom PD Leads work: Early Years, primary, secondary, Advanced Level, and Core Maths. NCETM Accredited PD Lead status is gained by successfully completing a development and accreditation training programme which involves face-to-face sessions, together with independent and school-based gap tasks, leading to accreditation by the NCETM.
