The 3-tier teacher development plan schools copy

Teacher turnover is expensive. The schools that keep their best staff all develop them on purpose — usually with the same three tiers.

Tier 1: everyone, always

Short micro-credentials every teacher does each year — assessment, differentiation, classroom practice. Cheap, frequent, universal.

Tier 2: your future leaders

Certification tracks for teachers stepping up: IGCSE, IB or CBC delivery, plus observed practicum. This is where ambition is paid back.

Tier 3: your specialists

Coaching and custom pathways for heads of department and exam leads, aligned to the school's improvement plan.
