This document discusses the accessibility challenges to science education in Cambodia. It notes that 75% of teachers, 96% of university students, and 67% of primary/secondary school pupils were killed or starved under the Khmer Rouge regime, with long-term impacts on Cambodia's education system. Currently, 71.2% of children aged 12-14 are not enrolled in secondary school. The document provides a theoretical framework and analyzes the formal rules, informal constraints, enforcement characteristics, and efforts to align the system to better support students with disabilities. It emphasizes overcoming institutional blockages rather than focusing solely on resource issues or compliance with accessibility guidelines.
