Students take written examinations at the end of the programme,
which are marked by external IB examiners. Students also complete
assessment tasks in the school, which are either initially marked
by teachers and then moderated by external moderators or sent
directly to external examiners.
The marks awarded for each course range from 1 (lowest) to 7
(highest). Students can also be awarded up to three additional
points for their combined results on theory of knowledge and the
extended essay. The diploma is awarded to students who gain at
least 24 points, subject to certain minimum levels of performance
across the whole programme and to satisfactory participation in
the creativity, action, service requirement. The highest total that a
Diploma Programme student can be awarded is 45 points.
Assessment is criterion-related, which means student performance
is measured against pre-specified assessment criteria based on the
aims and objectives of each subject curriculum, rather than the
performance of other students taking the same examinations. The
range of scores that students have attained remains statistically
stable, and universities value the rigour and consistency of Diploma
Programme assessment practice.

The IB Mission
The International Baccalaureate aims to develop inquiring,
knowledgeable and caring young people who help to create
a better and more peaceful world through intercultural
understanding and respect.
To this end, the organization works with schools, governments
and international organizations to develop challenging
programmes of international education and rigorous assessment.
These programmes encourage students across the world to become
active, compassionate and lifelong learners who understand that
other people, with their differences, can also be right.
Quality assurance and professional
Any school, or group of schools, wishing to offer one or more IB
programmes as an IBWorld School must first be authorized.
The requirements are the same for all schools, and the procedure
is designed to ensure that schools are well prepared to implement
the programme(s) successfully. All IBWorld Schools are required to
participate in an ongoing process of review and development, using
the same programme standards and practices.
As part of its ongoing commitment to the development of a highly
skilled global learning community, the IB provides a wide range of
high-quality professional development opportunities to help new,
experienced and expert school leaders and educators understand,
support, and successfully deliver IB programmes reflecting IB
standards and practices.
“At King Edward’s School we made the decision to move to
a solely IB Diploma curriculum because we believed that it
would provide a really challenging education and would
be the best preparation for university study”.
John Claughton, Chief Master, King Edward’s School, Birmingham UK.
