Hello, we are OSC
We are trusted by IB schools and teachers across the world to provide supplementary support for their students. Founded in 1990 by an IB teacher, we are still run by the founder’s daughter, Kim Polgreen, with the same commitment to quality, and to the IB philosophy itself. Our team is passionate about promoting international and community-mindedness through education. This is reflected in our mission statement.
We ensure that we provide the highest quality education support by only working with experienced and specialist IB teachers
Our teachers work for great IB schools during term time. In their holidays, they complement the work done in other IB schools through delivering our IB Revision Courses and Summer Programmes. Some quick facts about our teachers:
