The final stage of the IB continuum

We are an IB World School authorised for all three IB school programmes. The Diploma Programme is the final stage. Students who join from our MYP are already familiar with inquiry, criterion-based assessment and independent work. Students who join from another school are supported by their tutor and the Counselling Department from day one.

The programme

What is the Diploma Programme?

It is a two-year curriculum from the International Baccalaureate Organization. It combines six subjects studied in depth with three core components that every student completes. These components develop critical thinking, research skills and commitment to the community.

Theory of Knowledge (TOK)

Students reflect on how we know what we know. They analyse knowledge in each subject and learn to argue with sound judgement.

Extended Essay

An independent research paper of up to 4,000 words on a topic chosen by the student, guided by a supervisor. It is the best preparation for university-level work.

Creativity, Activity, Service (CAS)

Throughout the programme, students take part in artistic, sporting and community service projects, so they also grow outside the classroom.

Programme structure

Five subject groups

Each student takes six subjects, at least one from each group. At least three, and up to four, are studied at Higher Level (HL), in greater depth and with more teaching hours; the rest at Standard Level (SL).

Group 1

Studies in Language and Literature

Spanish A (HL).

Group 2

Language Acquisition

English B (SL).

Group 3

Individuals and Societies

History (SL), Business Management (HL) and Environmental Systems and Societies, ESS (SL).

Group 4

Sciences

Biology (HL), Chemistry (SL), Physics (SL) and Environmental Systems and Societies, ESS (SL).

Group 5

Mathematics

Analysis and Approaches (SL and HL) and Applications and Interpretation (SL).

How it is assessed

Each subject is graded from 1 to 7. TOK and the Extended Essay add up to 3 more points, for a maximum of 45. The final grade combines coursework assessed at school and external exams at the end of the second year, marked by IB examiners around the world.

Subjects tailored to each student

The choice of subjects and levels depends on what the student wants to study afterwards. The Counselling Department works it out with each student and their family before the first year begins. More about the programme on the IB website.

After the Diploma

University entrance in Spain and abroad

Under Royal Decree 534/2024 (in Spanish), IB Diploma holders can enter Spanish universities without taking the compulsory part of the PAU, the Spanish university entrance exam, and without having their qualification recognised.

Spanish universities

UNEDasiss certifies the entrance grade that gives access to university. With this certification, students apply for the degrees of their choice, just like any other student.

Universities abroad

The Diploma is recognised in more than 150 countries and valued by more than 2,000 universities worldwide, such as Harvard, Oxford, the Complutense University of Madrid and Pompeu Fabra University in Barcelona.

University counselling

The Counselling Department supports each student with subject choices, UNEDasiss certification and applications to each university.

Entrance is not the same as admission. The Diploma opens the door to university; a place on each degree depends on the student’s grades and on each university’s criteria. That is why we plan university entrance from the first year.

Frequently asked questions about the Diploma Programme

What is the IB Diploma Programme?
It is the International Baccalaureate Organization’s programme for students aged 16 to 18. It lasts two years and combines five subject groups with Theory of Knowledge, the Extended Essay and CAS (Creativity, Activity, Service). At Colegio Internacional San Cristóbal it is the final stage of the IB continuum, after the PYP and the MYP.
Can a student from another school join the Diploma Programme?
Yes. Students do not need to have taken the MYP. Before the first year begins, the student and their family meet the programme team and the Counselling Department to choose subjects and levels. The programme’s admissions policy is published in our IB policies (in Spanish).
Does the IB Diploma give access to university in Spain?
Yes. Under Royal Decree 534/2024, IB Diploma holders can enter Spanish universities without taking the compulsory part of the PAU and without having their qualification recognised. UNEDasiss certifies the entrance grade.
Which subjects can students choose?
Six subjects, at least one from each group: Spanish A (Language and Literature); English (Language Acquisition); History or Business Management (Individuals and Societies); Biology, Physics, Chemistry or Environmental Systems and Societies, ESS (Sciences); and Mathematics, either Analysis and Approaches or Applications and Interpretation. At least three subjects are taken at Higher Level.
How is the Diploma Programme assessed?
Each subject is graded from 1 to 7, and Theory of Knowledge and the Extended Essay add up to 3 more points, for a maximum of 45. The final grade combines coursework assessed at school and external exams at the end of the second year, marked by IB examiners.
IB Diploma or Spanish Baccalaureate?
It depends more on the student than on their grades. The Diploma Programme follows a more independent method: research, written work and critical thinking in every subject. It is also a good option if the student is considering studying outside Spain. The Spanish Baccalaureate follows a more traditional method: classroom teaching, subject-by-subject study and exams in each assessment period. It is the direct route to the PAU. The Counselling Department supports this choice with every family.
