Sotogrande International School
The IB from age 3 to 18, a boarding house for 150, polo and golf on the doorstep and the leading international school of southern Spain.
The character
SIS is where the families of Sotogrande, Marbella and Gibraltar educate their children, and where international boarders come for the IB and the climate. The academics are solid, the sport is exceptional (polo, sailing, golf, tennis), and the boarding house has a relaxed, Mediterranean feel. It is the only school on this list where a child can ride to a polo lesson after class.
Good for

Getting in
Rolling admissions with reports, assessment and interview; boarding from age 11.
What it costs in total
At about € 42,000 a year for boarding (€ 22,000 for day pupils), the 5 years from 13 to 18 add up to roughly €235,000 in today’s money including typical extras, before fee increases, tutoring and flights. The Education Cost Calculator adds inflation, extras and a second child.
