Student movements in developed democracies increasingly focus on the quality, not just the availability, of education. In the light of recent protests in France, examine the relevance of class size and infrastructure for learning outcomes in India.

In November 2026, French students blockaded high schools and universities. They demanded renovated buildings, smaller classes and more university places, which are demands about quality rather than access [1]. India faces the same question. Near-universal enrolment under Article 21A has not produced matching learning outcomes.

Lessons from France

• Averages hide gaps: France's primary class size (21.6) is close to the OECD average, but lower-secondary classes still average about 26 [2][4].
• Targeting works: France cut primary class sizes by close to 10%, mainly in priority-education (disadvantaged) areas [3].
• Class size has limits: The OECD finds the evidence linking class size to outcomes "mixed". In France, family background shapes results more strongly than in most OECD countries [5].

Why class size and infrastructure matter in India

• Distribution, not averages: India's PTR is 24:1, within the NEP 2020 norm of 30:1. Yet 1,00,843 single-teacher schools remain [6]. In these schools one teacher has to handle several grades at once, which drags down learning.
• Teaching methods: Smaller classes allow activity-based and remedial teaching. This is vital for foundational literacy and numeracy under NIPUN Bharat.
• Infrastructure enables attendance: The RTE Act 2009 sets norms for toilets, drinking water and libraries. These facilities affect whether children, especially girls, keep coming to school.

Why they are not enough

• Teacher quality: Even in France, 9.1% of secondary teachers are not fully qualified [2]. A small class with an untrained teacher gains little.
• Cost trade-off: Every extra class needs another teacher and another room. The OECD urges France to shift spending towards primary years [5], and that advice fits India too.
• PTR is not class size: PTR counts teachers who teach few hours or do office work, so real classrooms are larger than the ratio suggests.

Way forward

• UDISE+ should publish actual class size by stage, as the OECD's Education at a Glance does [4].
• Redeploy surplus teachers to single-teacher schools before hiring to meet average ratios.
• Target spending on aspirational districts and early grades, as France did in its priority zones [3].

Class size and infrastructure are necessary but not sufficient for learning. They work only alongside good teachers and targeted spending. India should move from hitting national averages to ensuring every classroom has enough teachers and decent facilities. This would deliver the substance of Article 21A and SDG 4 (quality education).
