We Teach for the Future

ISC is a progressive and innovative non-profit school, not afraid to make changes and ready to create extraordinary human beings prepared to face an unknown and defying future and make a difference in the world.

At a time when character, collaboration, creativity and other competencies are highly valued and needed to succeed in society, the importance of creating more complete human beings (your children) who are curious, have critical minds and can lead productive lives with strong social and emotional foundations is critical.

We call this Teaching for the Future.

Accreditation & Diplomas


We are the only school in the state of Paraná to offer the combination of three different diplomas to our students: the Brazilian (MEC), the American (AdvancED) and the International Baccalaureate (IB).
