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:
TDT Programmes
Offering and continuously developing our flagship suite of Professional Development Programmes to support school and system leaders in implementing effective staff development strategies.
Expert Schools Programmes,
National Professional Qualifications,
Associate Qualification in CPD Leadership, Pedagogical Coaching, Collaborative Enquiry
TDT Expert School Network
Stimulating demand for high quality CPD through the growing national and international network of schools and colleges engaging in our programmes. Our Expert Schools Network Membership provides world class, evidence informed professional learning, knowledge sharing and research. We foster collaboration and networking opportunities among teachers, school and system leaders, and educational organisations.
Advocacy
Publicising and disseminating research and insights, campaigning and advising government to raise the status of professional development.
We play an active role in advocating for the importance of teacher development at policy level; working with policymakers, educational bodies, and government agencies to shape policies that prioritise and support high-quality professional learning opportunities for teachers.
Our values and approach

Smart
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
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
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.
