76% — and what it means for children in Cambodia
Our Annual Report 2025 is built around a single number. Not because one number tells the whole story, but because it answers the question that matters most: are children learning more?
“Seventy-six per cent represents the measured improvement in learning outcomes recorded in classrooms taught by teachers trained by TDSO in 2025. That number belongs to the students.”
Son Nat, Executive Director
The 76% improvement is based on structured assessments, classroom observations, and comparative data collected across public primary schools in Siem Reap province, comparing performance before and after teachers applied TDSO’s student-centred training methods in their classrooms.
The change is driven by a shift in how teaching happens. When teachers move away from lecture-based instruction and towards structured, interactive methods, students engage more actively, practise language in meaningful ways, and develop the confidence to participate. The improvement shows up in both written scores and speaking ability, and in how students behave in the classroom.
2025 was also a year of institutional milestones. TDSO received formal accreditation from Cambodia’s Ministry of Education, Youth and Sports, confirming the national relevance of its programmes. A governing board was established to strengthen oversight and strategic direction. And TDSO delivered its first international training programme, hosting 20 teacher educators from Lao PDR at the Siem Reap campus.
Looking ahead, 2026 marks the beginning of a national rollout. TDSO will extend its programmes to 17 additional provinces, working in close collaboration with the Ministry of Education and sub-national education authorities.
