Grennaskolan offers a complete program of pre-university studies for boarding and day students. For the children of Swedish families living abroad or other families with Swedish connections, the school facilitates the maintenance of Swedish academic and cultural traditions. In addition, the IB program at the school offers students the opportunity to participate in a rigorous and internationally-accredited pre-university program.
Grennaskolan welcomes all qualified students from Sweden and abroad. The working language for the Swedish high school lines is Swedish, and for the IB program, English.
The school's plant comprises some 20 buildings including some of historical value as well as new constructions. They are used as classrooms, student residences, a large assembly space, library, and dining hall. The school also has newly-built, well-equipped science and computer laboratories. Grennaskolan currently shares an indoor athletic facility and playing fields with the local junior high school.
