What actually matters in the first year of running an ESL center.
Don't build your own curriculum from scratch in year one — it's the single biggest time sink for new centers. License or subscribe to an existing structured curriculum for the first year, then customize once you understand your specific students' needs.
Requirements vary heavily by country and whether you're running a formal school vs. a tutoring center — check your local education authority directly rather than assuming. This varies too much by jurisdiction for a general answer to be reliable.
Standardized, pre-built lesson materials matter more with limited staff, not less — every hour a teacher spends creating materials is an hour they're not teaching or the center isn't scaling. This is the single highest-leverage fix for small centers.
At minimum: vocabulary flashcards, a practice worksheet, a test/assessment sheet, and a lesson plan — all matched to the same vocabulary set. Anything less requires teachers to fill gaps themselves, which reintroduces the prep-time problem.
Under 10 is where ESL teaching actually works for this age group. Above that, individual speaking time per child drops below the threshold where language production develops — kids watch instead of participate. I've taught classes of 15+ and the honest truth is it becomes crowd management, not language teaching.
Spending money on a space before proving there's demand. I'd run a pilot — 5-10 students, rented room, borrowed materials — for one semester before signing a lease. The centers I've seen close early almost always over-invested in physical setup before they had a paying student base.
