Answer
The main difference is simple: public schools are free, while private schools charge fees. About 80–90% of children in Uruguay attend public schools, and roughly 10–15% attend private ones.
A public school can be a straightforward, suitable option for a family, especially where cost and proximity to home matter. A private school is more often chosen for additional features: languages, the daily schedule, infrastructure, meals, activities, or a more specific educational environment.
When choosing, do not look only at whether a school is private or public. The specific area, class composition, the administration’s approach, the child’s language needs, the schedule, and the family’s budget all matter, because the actual experience depends on the school, not just its category.
