International Baccalaureate (IB)

Charterhouse is an IB World School and offers the IB Diploma Programme. Since its conception in 1968, this highly reputed course of study has promoted international-mindedness as well as intellectual rigour and academic flexibility. It is likely to appeal to pupils who wish to develop these skills, as well as to those who do not feel ready to specialise in the way that has been traditional in this country.


Pupils study six subjects (including English, a second language, a humanity, a science and mathematics, as well as an arts subject or another language, humanity or science), with three of these taken at Standard Level and three at Higher Level (allowing for greater depth of study in those areas). Up to 7 points are awarded for each subject regardless of the level at which the subject is studied. In addition, three Core points are available for the quality of work in the Theory of Knowledge course as well as the Extended Essay. A total of 45 points is available overall and this allows universities carefully to differentiate an applicant’s attributes. It is also a requirement for the award of the Diploma that pupils should satisfactorily complete the CAS Programme. Further information about the IB Diploma Programme, can be found on the Charterhouse website and on the IB’s website:

Availability of subjects

Charterhouse intends to offer all IB Diploma courses as published above. If, however, a course does not attract sufficient interest to warrant it running, it may have to be withdrawn. Any affected prospective pupil will be notified as soon as possible if this situation pertains. In addition, the combination of Economics HL and Business and Management HL is not available (although one HL course combined with a SL course in these subjects is acceptable).


In order to ensure that all Carthusians follow a balanced and purposeful co-curricular programme in the Sixth Form, all Specialists will be required to complete a minimum of approximately fifty hours of participation in each of the following areas:


The Arts (such as Art, Music and Drama) and any other activity which involves creative thinking or expression, such as making a video, photography, contributing to periodicals, cooking, house décor, Lack of Talent, performing in Club etc.


Physical exertion contributing to a healthy lifestyle. There is a huge range of sports available at Charterhouse, but Action does not mean just sport: it can include activities such as hill-walking or cycling or environmental projects which are physically demanding.


Unpaid and voluntary activity to benefit another individual, a group or community. Some excellent service projects are already in place at Charterhouse, such as teaching in primary schools, visits to the elderly, working at the Royal Surrey County Hospital, instructing younger cadets in the CCF, acting as House or School Monitors, peer mentoring, volunteering as part of the Duke of Edinburgh’s Award Scheme, producing charity concerts…etc.

Specialists are encouraged to come up with their own ideas for CAS activities.

One CAS activity should be a Project, which will involve two or all three elements of CAS (for example, football coaching involves both Action and Service) and collaboration with at least one other person.


Fifty hours represents about an hour a week between September of the first year and March of the second. Time spent on CAS activities in the holidays also counts towards fulfilling the commitment required.

Planning and Reflection

By the end of two years, Specialists will be able to provide evidence that they have increased their awareness of their own strengths and areas for growth; undertaken new challenges; planned and initiated activities; worked collaboratively with others; shown perseverance and commitment in their activities; engaged with issues of global importance; considered the ethical implications of their actions; and developed new skills.

However, CAS is not just about participating in various activities. Specialists will be required to reflect on their experiences and to make full use of their co-curricular activities as opportunities for learning. So, with the guidance of their tutor, Specialists will plan their CAS activities and at intervals think about the progress they are making. That thinking will inform the rest of the activity. Planning and reflection will be recorded.  CAS activities may form part of a pupil’s commitments in completing the Duke of Edinburgh’s Gold Award.
