TDT: The smart, heart, humble education charity for professional development



We help give you the clarity, confidence and capacity to build and lead a culture of expertise in your school or trust, where empowered staff thrive so that children succeed.

Our reflective, diagnostic approach gives leaders confidence that effective professional development is prioritised and that all staff participate meaningfully in tailored, evidence based training that builds expertise in an empowering way. External evaluations of our work show positive impact on teaching and learning, morale and teacher retention.

Using a strong international evidence base of what constitutes successful teacher professional development, we work with partners across the education sector to promote the principles of effective and impactful Continuing Professional Development (CPD) through:

Our values and approach

Smart icon image


We are SMART – all of our work is deeply rooted in evidence. We want to know what works and seek out the brightest and the best minds to help shape our programmes, research and advocacy.

Heart icon image


We have HEART – teaching and learning is about people and connection. Even the strongest evidence for improvement will be ineffective if not implemented by expert, empowered teachers at the front of the classroom. 

Humble icon image


We are HUMBLE – we are always curious, we are always learning. We are led by the evidence, but we also have the humility to keep testing our understanding and adapt.
