The indicator “Number of Schools by Availability of Infrastructure and Facilities” is a comprehensive measure of the overall readiness and quality of the education system. It captures whether schools have essential infrastructure such as classrooms, toilets, drinking water, electricity, libraries, laboratories, playgrounds, and digital facilities that are necessary for effective teaching and learning. Adequate infrastructure directly influences student learning outcomes, health, safety, and dignity. Well-equipped classrooms create a conducive learning environment, while functional sanitation and water facilities are critical for hygiene, attendance, and gender equity—particularly for adolescent girls. Libraries and laboratories support academic enrichment, practical learning, and the development of critical thinking skills, while digital infrastructure enables access to modern educational resources.

From an equity perspective, this indicator highlights disparities in school facilities across regions, management types, and social groups. Schools lacking basic infrastructure often serve disadvantaged populations, reinforcing cycles of inequality and poor educational outcomes. At a policy and planning level, tracking schools by availability of infrastructure and facilities helps governments and stakeholders assess compliance with education standards, monitor progress of infrastructure development programmes, and prioritise investments. The indicator supports evidence-based decision-making aimed at improving school quality, ensuring minimum service levels, and delivering safe, inclusive, and effective learning environments for all students.
