About Us

BHS is a welcoming, dynamic, new-age school for the post-Covid world.


Centrally located in Barcelona with perfect access to all modes of public transportation, BHS is the perfect international and American school in the heart of Barcelona city, instead of outside the city like the other international and American schools. 

While BHS uses the American school education system, it serves as the international school in Barcelona for the global community.  Accordingly, BHS is the most international school in Barcelona, as no nationality is larger than 20% of the student body.

BHS is a fun, engaging, caring and diverse environment (across multiple grade levels and nationalities) where students come together as one big family and learn through flexible, modern and innovative teaching methods.


BHS lives by the promise and mission to help teenagers excel academically, socially and psychologically.


Delivering on its promise and mission while maintaining a "10 out of 10 ONLY" teacher quality standard known as the "BHS Teacher spark", along with its innovative and flexible digital learning platform, are reasons Why BHS has grown so rapidly so fast.

BHS started with only 5 students in its first year (2020-2021) and then grew to over 30 students by its 2nd year (2021-2022).  BHS currently has an enrollment of over 75 students in this school year (2022-2023) as it continues to add the best teachers in Barcelona.  In the next school year (2023-2024), BHS plans to have an enrollment of 150 students.

BHS is the brainchild of Akida Mashaka, an American from Los Angeles, California.  Akida created BHS because he recognized certain problems with American schools in Barcelona, including schools with IB and British schools, especially Catalan schools, and indeed, the entire school system in Spain and throughout the world.  Unlike other schools, Akida created a school that focuses on smaller class size, a fun, social and individualized learning environment in a family-like environment, with innovative digital learning tools, career and university advisement, and emotional intelligence skills necessary to be successful in today's world, rather than schools that are still the same as when students' parents attended them.  Akida is a graduate of Harvard Law School and attended university in USA on a tennis scholarship.  Akida graduated #1 in Psychology in his university class, and accordingly, student mental health is a very important component of BHS.
