Mission

The TDT states its mission as providing “effective professional development in schools helps teachers thrive and children succeed", as well as to "make exceptional staff development achievable for every school."

History

In April 2012, the British government closed the Training and Development Agency for Schools, the national body formerly responsible for teachers’ training and professional development.
In response to the planned closure, Teacher Development Trust was founded by teachers as a new agency aiming to support teachers’ professional learning.
Between 2012 and 2017, the charity coordinated the TDT Advisor platform and monitored it alongside The Educational Endowment Foundation and Sutton Trust. This database provided listings and ratings for professional development training courses, consultancy, and other services.
TDT published its first significant research project, “Developing Great Teaching”, in 2015.
In 2017, the charity launched the first cohort of the “Associate Qualification in CPD Leadership”. As of 2025, 12 cohorts of school leaders have learned through this qualification.
For a time, Teacher Development Trust also operated the Teacher Development Trust Network, an opt-in UK school network whose members shared evidence-based professional development practice.
Teacher Development Trust worked as one of the government’s recognised providers of National Professional Qualifications for teachers and leaders for five years. In October 2024, the charity officially withdrew from providing future NPQs, reporting that they had chosen to focus on supporting schools through research and their alternative programmes.

Teacher Development Trust runs a number of national and international programmes. These are intended to build participants’ skills and expertise in CPD leadership in education, leading to improved practice in schools. They currently include:Building Expert Schools.
