In each IB school the IB coordinator, together with the IB faculty of teachers, is responsible for the fulfilment of the requirements.

Lyseonpuiston lukio is an independent, authorized International Baccalaureate (later IB) school since 2004. Lyseonpuiston lukio IBDP (International Baccalaureate Diploma Programme) comprises three years: preparatory year (pre-IB), IB1 year and IB2 year. During the pre-year, students take courses designed to prepare them for the two-year IB Diploma Programme. The working language in the courses is English.

Several assignments by the students are sent to be assessed by external moderators around the world.
