Why IB · Why Base

Why study the Diploma Programme
at Base.

Diploma Programme students at Base International School, La Moraleja
Six reasons · Not just one

What makes the IB at Base different
is how your child experiences it every day.

The International Baccalaureate Diploma Programme curriculum is the same at every IB World School. What changes from one school to another is the level of support, the teaching team, the assessment approach, the real level of English in the classroom and the culture that surrounds it all. These are the six things that set the Diploma at Base apart from other IB schools in Madrid.

Secondary students at Base International School, IB continuity
01 · Continuity

The same way of learning,
year after year.

We deliver the MYP throughout Secondary and the Diploma Programme in Bachillerato, both authorised by the International Baccalaureate. In Early Years and Primary we are a PYP candidate school and are in the process of implementing the programme.

The IB is a way of learning built on inquiry and independent work. Students who enter the Diploma from within Base arrive with that approach already deeply embedded. Those who join from other schools find a teaching team that has been working this way across every stage.

✦
MYP and Diploma Programme authorised by the IB. PYP in the authorisation process in Early Years and Primary.
English class at Base International School
02 · English with evidence

Real English,
backed by real results.

English B at Higher Level requires a C1 level to achieve strong results. At Base, students reach the final IB exam with a level above what is required.

Taking English B HL alongside Business Management (taught in English) also qualifies them for the IB Bilingual Diploma, an official distinction recognising their ability to work academically in two languages.

✦
100% pass rate in Cambridge Proficiency C2 in 2024-25. Average score in English B HL: 6.20 / 7 (IBO world average: 4.92).
Classroom at Base International School, personalised guidance
03 · Guidance

Small classes and personal guidance
you can count on.

Our Guidance Department includes psychologists specialised by stage, a special educational needs coordinator, a personal counsellor and a designated safeguarding lead.

The IB coordinator works with each Diploma student individually throughout the two years. And our teaching staff have an average tenure of 12.35 years: Diploma teachers stay year after year.

✦
Ratio of 9.9 students per teacher. Guidance ratio above UNESCO recommendations.
And also

Three more reasons families choose Base.

04 · Assessment

Transparent assessment and predicted grades.

Two weeks of mock exams in Year 1 and Year 2 replicate the final IB exams in format and content.

In Year 2, we add a predicted grade that combines internal assessments with mock results using official IB weightings. By the time the May session arrives, they already know where they stand.

05 · Identity

Secular, no uniform, in La Moraleja since 1962.

Base was founded under the inspiration of the Institución Libre de Enseñanza. More than 60 years later, we remain private, co-educational, secular and uniform-free.

It reflects a clear approach to education, rooted in a close relationship between teacher and student and in freedom of thought.

06 · International network

Backed by Affinitas Education.

Since 2024, we are part of a group with over 20 schools in Spain, Mexico, Italy and the United States.

For Diploma students, this means a network of multi-campus summer camps, international exchanges, shared standards and access to a global alumni community. Each school keeps its own identity.

The decision ahead

Spanish Bachillerato
or IB Diploma Programme.

Base offers two independent upper-secondary programmes, each with its own curriculum, teaching team and timetable. Both lead to Spanish university: the Bachillerato through the PAU entrance exam, and the IB Diploma through official recognition as the Spanish Bachiller qualification (Royal Decree 534/2024) plus the UNED accreditation for university entry. The Diploma also opens access to universities in over 100 countries.

A figure worth looking at carefully: in the 2024-25 exam session, the average university entry score for IB students at Base was 11.26 out of 14, compared to 10.47 for Spanish Bachillerato students. These are two different programmes with different levels of demand. The IB asks more. In return, it opens more doors.

A clear profile

When the Diploma Programme
makes sense.

The Diploma Programme is demanding, and it does not suit every profile in the same way. That is why, in the admissions interview, we talk calmly about grades, about the level of English and about what each student wants to study afterwards, so that together we choose the option that fits them best. These are the profiles that work best with each one.

IB Diploma Programme

The IB is a good fit
if your child...

Has an average grade of 7 or above in recent years of secondary school.
Holds a C1 English level or equivalent, or is close to reaching it.
Enjoys a range of subjects and wants to keep different areas of knowledge open.
Works with independence and manages their time without constant reminders.
Has a real interest in learning in depth, through essays, research and long-term projects.
Is considering studying outside Spain or wants to keep that possibility open.

It may be a better fit
if your child...

Has a clear idea of the degree they want to study in Spain and prefers to optimise their score through the familiar PAU route.
Prefers a less intensive pace during the two years, with free afternoons for personal study.
Feels more comfortable with assessment based on final exams rather than extended essays, coursework and research projects.
💬
The right choice is the one that fits the student. The Admissions team can help you make this decision through an honest conversation about your child's profile, grades and goals.

Student in the science lab at Base International School
Two years of Bachillerato

The IB is two demanding years.
How they experience each day matters as much as the lessons themselves.

The morning commute, lunch, an afternoon of sport or library time, the school nurse if something comes up. This is what it means in practice to be a student at Base, and it is a part of the decision that matters just as much as the academic programme.

Frequently asked questions · IB Diploma Programme

The questions families ask most
before visiting.

Can my child join the IB Diploma Programme if they come from another school?+
Yes. Students from other schools can join in Year 1 of Bachillerato once they have completed the admissions process. This includes interviews, a review of their academic record and, where necessary, placement tests. A C1 level of English or equivalent is also recommended. Each application is considered individually and as a whole, to assess how well the student suits the Diploma Programme.
What level of English do they need to start the Diploma Programme?+
We recommend a C1 level or equivalent. This is the level that the IBO itself considers necessary to achieve strong results in English B at Higher Level. If there is no prior certification, the English Department at Base carries out an internal assessment to evaluate the student's actual level.
Is the IB Diploma valid for accessing Spanish universities?+
Yes. The IB Diploma is officially recognised as the Spanish Bachiller qualification under Royal Decree 534/2024. For university entry, the conversion of the IB score into an entry score is carried out by the UNED through its accreditation, a procedure the Guidance Department helps every family prepare. In the class of 2024-25, the average university entry score for IB students at Base was 11.26 out of 14.
How much does the IB Diploma cost at Base?+
The Diploma Programme fees for the 2026-27 academic year are €13,600 a year, in both Year 1 (10 monthly payments) and Year 2 (9 monthly payments). Tuition includes textbooks and school materials, free extended hours from 7:30 to 18:30, one-day excursions and cultural activities, the psycho-pedagogical orientation service and Saturdays with families. The dining hall, school transport and extracurricular activities are optional services with their own fees. Full, up-to-date fees are available at colegiobase.com/en/fees.
What happens if they don't achieve the full IB Diploma?+
Although uncommon, it is possible not to reach the 24 points required for the full Diploma. In that case, the student receives official results for the individual subjects they sat and can re-sit the subjects they need in the November session to reach the required score. The IB coordinator and the Guidance Department work with the family to evaluate the options for university access, which may include partial recognition of studies or the PAU exam route.
Where is the school? Is there transport from central Madrid?+
Base International School is located at C. del Camino Ancho, 10 · La Moraleja, Alcobendas (28109 Madrid). Direct access from the A-1 motorway. We run school bus routes across central and northern Madrid, with routes designed specifically for Bachillerato students. They cover central Madrid (Castellana, Velázquez, Narváez) through to the northern zone (Sanchinarro, Las Tablas, Mirasierra, Montecarmelo, Tres Cantos, Paracuellos). Routes and stops may vary depending on demand each school year. Full information at colegiobase.com/en/bus-routes.
How many hours of independent study per week should they expect?+
The programme requires sustained effort. On top of the two afternoon classes per week, there is personal study time at home, preparation of internal assessments, the Extended Essay and CAS. Students who manage their time well find it demanding but manageable. The IB coordination team monitors workload throughout the year to identify pressure points before they build up.
