Answer
In Uruguay's free public schools, students are given tablets or laptops. Free meals are also provided in primary and secondary public schools. This reduces families' initial expenses.
The devices are given to children for study, and the data separately states that they are not taken away immediately after use. This is part of school support that reduces family spending on basic learning tools.
At the same time, free school does not mean a complete absence of associated costs. The family may still need clothes, transport, additional school supplies, extracurricular activities, or language support, but meals and a learning device already cover some of the mandatory costs and make it much easier to get started after moving.
