Choosing between a Portuguese private school and an international school

When choosing between a Portuguese private school and an international school, parents should take several factors into consideration. If the family plans to stay in Portugal permanently, a Portuguese private school may be the best choice for the child's full integration into Portuguese society. It is significantly cheaper (savings of €8,000 to €15,000 per year) and provides an in-depth study of the Portuguese language and culture.

Cost of Portuguese Private Schools
Private education in Portuguese schools typically costs between €400 and €500 per month for primary and secondary pupils. In Lisbon, prices may be slightly higher — between €300 and €500 per month, plus approximately €120 per month for lunches. In other cities, the cost may be lower.
In annual terms, this represents approximately €4,800–€6,000 per year for education, plus additional expenses. The basic fees generally include:

Registration fee: approximately €300 per year
Textbooks and teaching materials: up to €300
School uniform: €100–€200
Meals: €1,200–€1,500 per year (if not included in the basic tuition)

Overall, parents can expect total expenses of €6,000 to €8,500 per year per child at a Portuguese private school, depending on the region and specific institution.
