You did it, Class of 2026!
Grades 6 - 10
In Grades 6 through 10, students experience a learning environment designed to build strong academic foundations, foster independence, and encourage self-discovery. As in the elementary school, our curriculum draws on internationally recognized standards, including AERO, Common Core, and Next Generation Science Standards, ensuring coherence, rigor, and relevance across subjects.
World language acquisition, the arts, technology, and physical education are all integrated into a well-rounded program that values both academic growth and personal development. With increasing opportunities for choice, leadership, and creativity, students in Grades 6–10 develop the confidence and skills to take ownership of their learning and begin exploring areas of interest and passion.

What makes the Secondary School Special ?
Athletics and International Sports Competitions
Our secondary students have a range of athletic opportunities available to them when they become a student at ISK. We are a founding member of the PAAC (Polish Athletics and Activities Conference) and a member of the CEESA (Central and Eastern European Schools Association). As a result our student athletes travel during the season to participate in regional and international competitions competing against other international schools. During the season students benefit from experienced onsite coaches who foster their interests and develop their skills.


Co-Curricular Activities and Leadership Clubs
When students are provided with opportunities to follow their interests and develop their leadership skills, their well-being increases and they have a stronger connection to their school. That is why activities at ISK are not extra-curricular activities, but they are co-curricular activities. That means they run alongside of our academic program. Student clubs like the photography club or garden club run during the school day during our innovative "Period 3" block. In addition to sports opportunities, students also have the opportunity to pursue other interests through our co-curricular activities offerings. Our co-curricular activities are listed below.
