OUR HISTORY
The Teacher Development Support Organization, formerly know as The Angkor Tree Project is the result of long term cooperation between enthusiastic Cambodian teachers and various western supporters. The project has its roots in Cambodia and is run by the people in Cambodia. The western partners give their support and help where they can.
It all started as a small initiative, providing free English classes to neighbourhood kids. Under a thatched roof, protected from the scorching heat of the tropical sun and sheltered from the sometimes heavy rain showers, kids discovered the richness and joy of acquiring English as a second language.
As demand grew, we transformed the living room into a second classroom. A second teacher joined the team. And when we had to add another classroom, not more than a few weeks later, we experienced that the real challenge was finding well-trained teachers.
We decided to provide training to our own staff, and why not, to make these training sessions also available for teachers in other NGOs. The Teacher Training Centre was born!
A professional teacher-trainer joined the young team, and suddenly things went at warp speed; the number of teachers requesting to join the training sessions increased rapidly. At the same time, we decided to add Language training for teachers to our portfolio.
The pandemic has catapulted education into the 21st century! Computers, the internet, distance learning, blended learning …it all became a necessity. IT literacy has become an absolute necessity for all those involved in education, especially teachers. Hence our IT-training programs.

OUR VISION
At The Teacher Development Support Organisation , we believe that no child should be forced to beg or work. We believe that they have the right to enjoy their childhood – to learn, play, make friends and grow in a safe and happy environment.
We strongly support the United Nations’ sustainable development goals and commit to contributing primarily to the goal of quality education: ensure inclusive and equitable quality education and promote lifelong learning opportunities for all.
We encourage multilingual education as an important lever to ensure that learners have access to high quality educational opportunities as they work towards becoming multilingual, successful and responsible members of an increasingly diverse global society.

OUR MISSION
We provide free and high-quality English Language Classes for children and adolescents who have no access to these in regular schools.
Great teachers help create great students. Research shows that an inspiring and informed teacher is the most important school-related factor influencing student achievement. We train, coach and support both new and experienced educators to become best-in-class.
21st-century technologies have their place in every classroom. We support students, teachers and educational institutions using and implementing technology as an integrated part of everyday school school-life.

OUR VALUES
Fairness and transparency: we commit to using the resources entrusted to us solely for the organisation’s objectives and to communicate regularly, timely and entirely on our activities and progress.
Service to the community: we commit to letting the interest of the local and global communities take precedence over our personal interest, even over the organisation’s interest.
Excellence and continuous improvement: we commit to permanently striving to improve the quality of our services and programs.
Our values are translated in a number of clear codes and policies.
