Boarding
We offer Prime Boarding to students from the age of 13, a home away from home, only 10 minutes away from the Estoril campus and 20 minutes away from the Sintra campus, where they will feel welcome and accommodated, with transport, meals and a fee that includes, besides the above, school fees, books, pocket money, uniforms, registration and personal accident insurance.
Students are encouraged to create their own activities within the premises in their academic and study free time, such as reading, board games, basketball, constructive and educational visits, as well as the privilege of sailing on certain weekends and/or holiday times, by agreement between parents and school management.
As the first International School in the area with a Boarding School, at Prime Boarding students are encouraged to explore who they are and have the opportunity to join in any activity that suits their interests.
