In the Lancasterian system, a single classroom could accommodate between 200 and 1,000 pupils.1

This monitorial approach relied on a highly structured environment where students were seated in rows of 10. To manage such large numbers, the adult schoolmaster taught a group of monitors—proficient students—who then relayed the lessons to their respective rows.1

The system emphasized strict discipline and military-like precision, with monitors also responsible for administrative tasks such as taking attendance, examining pupils, and distributing materials. While this method allowed for mass education and significant economies, it was often criticized for reducing learning to rote memorization and drill, leaving little room for individual initiative or creative thought.1
