School of the World was born in Tamarindo and is one of the very few actually local schools (not one of the giant ones that sends people everywhere). The Spanish is taught to international standards and the schools offers college credit for the classes. You can also take yoga, photography, and surf lessons from their well trained professionals. The staff is really dedicated to making the experience educational on many fronts and making sure the students have a really great time.
The idea of this schools is to take a creative approach to learning by combining Spanish language immersion with art workshops and adventure travel so that the students get a comprehensive, fun, cultural experience. Take classes for college credit, learn Spanish and combine it with photography, surfing, or art.
