The IB Diploma Programme is a demanding and robust programme of education which students follow at the ages of 16-19. The DP has been recognised as being a strong qualification by universities across the globe, and by leading employers. The DP ensures that students: develop their intellect with due ethical consideration, acquire a breadth of knowledge by studying subjects from 6 subject groups (unlike Advanced level where students generally choose three subjects), and undertake in-depth research into an area of personal interest.

The actual subjects studied include a choice of language, anadditional language, a social science, an experimental science and mathematics. In addition to this students then choose an either arts subject or can choose a second subject form the original 5 groups. Three core elements are also required: that extended essay, completion of the Theory of Knowledge course and Creativity, Action and Service (CAS), which is a range of activities which run alongside the academic programme. Assessment is completed by both internal means and by external examination. Each course is marked and students awarded a score between 1 (the lowest), to 7 (the highest). The diploma is awarded to students who achieve a score of at least 24 points.


The International Baccalaureate (IB) Diploma, a widely accepted pre-university qualification, was developed in the 1960s as an educational standard for a globalising world. If you want to attend university in another country, or you just want to infuse your education with an international perspective, then the IB diploma could be a good option for you.

Excellent writing skills will be indispensable here: each course is partly assessed on written work, and students are required to submit an extended essay as well. To support you in all your writing endeavours, Marked by Teachers has amassed a collection of student-submitted IB essays covering everything fromthe group 4 projects to world literature. Study the teacher-marked and peer-reviewed examples to learn how to edit your own essays, and produce highly polished work.

After leaving school, you'll have the chance to attend university in another country if you wish; today, the IB diploma is recognised by over 2,000 institutions around the world. But even if you stay at home, you'll be well prepared to build a career in today's globalised economy.
