As a leading state grammar school, we have moved from offering the “dual economy” of A levels and International Baccalaureate to an IB-only sixth-form curriculum, as our students have found that the IB is more effective in preparing them for undergraduate study and future success. The core elements of the extended essay and theory of knowledge, as well as the depth of academic understanding in higher-level and standard-level subjects, means they begin university ahead of their peers. The emphasis on understanding, discovery and investigation makes the IB different from A levels. It is a springboard for university success.
