The understaffing crisis
CBNM had been losing English teachers to international schools paying double for the same role. Their in-house English program was understaffed for the third year running; substitute teachers were filling 30% of slots.
The Koydo partnership shape
Rather than hire 8 more in-house English teachers, CBNM contracted with Koydo for 240+ weekly tutor hours across 16 cohorts. The school admin team handled scheduling + roster; tutors lived in Mexico City, Buenos Aires, and Boston (3 time zones).
Cultural fit was the bigger lift
The technical migration was fast (3 weeks). The cultural lift was longer (6 months) — parents had to trust online tutors as much as they trusted in-person ones, students had to build relationships with adults they'd never meet in person. By month 6, CBNM was getting more parent satisfaction on the Koydo cohorts than the legacy in-person ones.
What changed at the school level
The principal stopped spending 20% of her week on substitute-teacher scrambling. The English coordinator became a curriculum lead instead of a recruiter. The budget picture stabilized — the school could plan a full year of English instruction with confidence, instead of scrambling each year to fund whatever teachers they could keep.
