Cambodians Developing Cambodian Teachers
A team of 50+ Cambodian education professionals
improving teaching quality from the classroom up,
embedding proven methods into the national education system.
Real change first happens in the classroom,
not the meeting room.
We Implement
We train teachers in new teaching approaches directly in their classrooms.
We Validate
We gather proof that these approaches improve teaching practice and student learning outcomes.We Institutionalise
We embed these approaches into national in-service teacher training structures.We Transfer
National Insitutions deliver independently. Our role becomes obsolete by design.Three elements drive this pathway
In-Service
Training
Working with Practising Teachers
TDSO works with teachers already in classrooms, not pre-service training. This in-service focus allows us to address the immediate realities teachers face, limited resources, large classes, diverse student needs, and generate solutions that work in actual Cambodian schools.
→ Direct classroom coaching and observation
→ Peer collaboration and learning communities
→ Immediate application with students
→ Ongoing support throughout the school year
→ Career-long professional development
→ Evidence-based refinement
This classroom-based implementation generates the practical expertise we then institutionalise through national training programmes, ensuring what we scale has been proven to work.
CLT
Communicative Language Teaching
Our Foundation in Proven Pedagogy
We train English teachers using the Communicative Language Teaching approach (CLT), a research-backed methodology that revolutionised language education globally. CLT requires student interaction, active participation, and practice-based learning, shifting from rote memorisation to meaningful communication.
→ Student-centred interaction (not teacher-centred lecture)
→ Practice-based learning (not rote memorisation)
→ Meaningful communication (not grammar drills)
→ Real-world application (not abstract exercises)
→ Continuous feedback and refinement
→ Evidence-based effectiveness
This proven methodology, validated by decades of research and practice worldwide, forms the foundation from which our transferable approaches emerge.
TPATM
Transferable Pedagogical Approaches
From English Teaching to All Subjects
As teachers master CLT for English teaching, we recognise that its core approaches,student interaction, practice-based learning, and systematic progression work powerfully across all subjects. We formalised these transferable elements as TPA: our framework for student-centred pedagogy applicable beyond language learning.
→ Practice-Based Learning
→ Peer Collaboration
→ Systematic Progression
→ Subject-Specific Application
→ Continuous Coaching and Support
→ Evidence-Based Refinement
Teachers apply TPA approaches across all subjects they each, transforming not just their English classes but their entire teaching practice.
What This Achieves
Transforming students, teachers, and systems
Improved Student
Learning

How we work
Building capacity locally, scaling nationally, sharing expertise globally
Siem Reap Centre of Expertise
Innovation, Development, and Provincial Delivery
Our Siem Reap centre serves dual functions: developing and validating programmes for national scaling, while delivering teacher training directly across Siem Reap province.
Centre Activities
→ Direct Teacher Training
400+ teachers annually across 100+ schools in Siem Reap province (16.000+ students)
→ Practice School
500 students in demonstration classrooms where we test methods and teachers observe CLT in action
→ Programme Development
Creating and refining new pedagogical
approaches for national rollout
→ Materials & Resources
Developing curriculum and tools for
nationwide TEI delivery
→ Trainer Development
Equipping facilitators and coaches before provincial deployment
Home to 40+ staff, Siem Reap combines operational delivery with research and innovation, ensuring programmes are proven in practice before scaling nationally.
National Network
Systematic Capacity Transfer Across All Provinces
We work within 18 MoEYS Teacher Education Institutions strategically located to serve all of Cambodia’s 25 provinces. Through systematic capacity building, TEI staff gain full capability to deliver independently and at scale.
Network approach:
→ Year 1
We deliver while TEI staff observe and learn our methods
→ Year 2
We co-deliver with TEI staff, building their expertise
→ Year 3
TEI staff deliver with our coaching and quality support
→ Year 4
TEI delivers independently, sustaining and scaling programmes
→ Result
Scale multiplies from 2,000 to 10,000+ teachers annually (400.000+ students)
This network ensures MoEYS owns delivery capacity, provincial institutions operate without external support, and government systems strengthen rather than depend on NGO infrastructure.
International Support
Sharing Cambodian Innovation Regionally
We provide technical assistance to education organisations and governments, adapting our CLT-to-TPA framework for their contexts. This validates that the methodology developed in Cambodian classrooms transfers effectively across countries and systems.
What We Provide
→ Methodology Transfer
Supporting adaptation of CLT→TPA framework to local contexts
→ Technical Assistance
Advising on teacher training programme design and implementation
→ Capacity Building
Training local educators to deliver adapted programmes independently
→ Knowledge Exchange
Sharing lessons learned from Cambodian experience
→ Quality Assurance
Supporting evidence-based approach to teacher development
Our international work positions Cambodia as a regional leader in teacher development innovation and proves TPA’s transferability beyond its country of origin.
