The short verdict
If your child will almost certainly attend a Spanish university and the family is settled in Spain, the Bachillerato is the natural route. It is the native qualification, it leads directly to the entrance exam that Spanish universities use, and it costs nothing extra at a state or concertado school. If your child may apply to universities outside Spain, or the family may move again, the IB Diploma travels more cleanly and is read fluently by selective universities worldwide. Neither qualification is a soft option, and a strong result in either keeps a capable child in contention for good universities. The decision is less about academic prestige and more about where the child is likely to apply from. For the wider curriculum picture, see our IB curriculum guide and the Spain country guide, which covers the dual pathway many Spanish schools now run.

The Spanish Bachillerato explained
The Bachillerato is the Spanish post compulsory qualification, taken across two years at ages sixteen to eighteen after a student completes compulsory secondary education, known as ESO. Rather than the broad six subject spread of the IB, the Bachillerato asks the student to choose a modalidad, a track that orients the two years around a field. The main tracks are sciences and technology, humanities and social sciences, and arts, with a more general track introduced under the most recent education reform. A student takes a set of core subjects common to all tracks, including Spanish language and literature, a foreign language, philosophy and the history of Spain, alongside the modality subjects that define the chosen field.
The qualification culminates in the university entrance examination, the EBAU, also called the PAU and still widely known by its historic name, Selectividad. The exam is usually sat in June with a second opportunity later in the summer. It has a compulsory general phase covering core subjects, where the student writes on Spanish language, a foreign language, the history of Spain and a modality subject, and an optional specific phase that allows additional subject exams to raise the admission mark for competitive courses. The final figure a Spanish university uses combines the Bachillerato school record with the entrance exam result, so the two years of coursework carry real weight rather than resting on a single set of finals. For Spanish universities this is the cleanest possible route, and around a quarter of Spanish undergraduate programmes are now also taught in English, widening the onward options for a Bachillerato graduate who stays in the system.

The IB Diploma explained
The International Baccalaureate Diploma is a two year qualification taken over the same ages, sixteen to eighteen. A candidate studies six subjects drawn from six prescribed groups, three at higher level and three at standard level, alongside three core requirements: Theory of Knowledge, the Extended Essay of four thousand words, and a CAS portfolio of creativity, activity and service. Each subject is scored from one to seven, and the maximum diploma score is forty five, with up to three bonus points for Theory of Knowledge and the Extended Essay combined. The breadth is the defining feature: two languages and mathematics are compulsory, so the child cannot drop a weak area in the way a Bachillerato modalidad or a set of A Levels allows. For the full structure, our IB curriculum guide sets out the groups, the core and the scoring in detail.
Where the Bachillerato concentrates effort on a chosen field and the entrance exam, the IB spreads it across six subjects and the core for the whole two years. The trade off is real. The IB child keeps going in subjects they might prefer to drop, but emerges with a balanced, internationally legible profile that selective universities in many countries read without translation. For a family whose onward destination is uncertain, that legibility is the single strongest argument for the diploma. The structural debate between the IB and other senior routes is set out further in our IB vs A Levels and French Baccalaureate vs IB comparisons, which apply the same reasoning to the British and French systems.
Which suits which child
The Bachillerato suits a child who is settled in Spain, comfortable studying in Spanish, and most likely to apply to a Spanish university. It suits a family that values the lower cost and the native onward route, and a child who prefers to orient the final two years around a chosen field rather than carry six subjects plus a compulsory core. A child with strong Spanish who has decided early on a Spanish degree will find the Bachillerato the most direct and least expensive path, and the EBAU is the qualification Spanish admissions officers read every day.
The IB Diploma suits a child who may apply abroad, who thrives on breadth, and who is comfortable in two languages and in mathematics. It suits a mobile family that cannot predict the next country, because the diploma slots into selective admissions almost anywhere. It also suits a child whose interests are still forming, because the required breadth keeps options open rather than narrowing the field at sixteen. The honest summary is that the better choice follows the likely application destination more than the child's raw ability; a capable child succeeds in either, and the question is which system serves the onward plan.
How schools offer each
In Spain the two qualifications are offered by different parts of the market, though the line is blurring. The Bachillerato is the standard senior route at Spanish state schools, at concertado schools, and at bilingual Spanish private schools, where it is delivered in Spanish with a foreign language as a subject. The IB Diploma is the dominant senior route at the international schools and at a growing number of Spanish private schools that have added IB authorisation to serve internationally minded families. Some schools now run a dual pathway, offering the Bachillerato and the IB Diploma side by side at sixth form, which preserves the Spanish onward route while keeping the internationally portable qualification in reach. This hybrid has gained popularity among families with uncertain onward plans.
When you visit a school, ask which qualification its strongest results sit in and how many students take each route, because a school set up to deliver the Bachillerato well is not automatically set up to deliver the IB well, and the reverse is equally true. Confirm the language of instruction across the two years, the support for a non native Spanish speaker if you are choosing the Bachillerato, and the university destinations of recent leavers on each pathway.

FAQ
Is the Spanish Bachillerato or the IB harder? Neither is soft. The IB demands sustained competence across six subjects plus a compulsory core, so the workload is broad and continuous. The Bachillerato narrows to a chosen modalidad and culminates in the EBAU entrance exam. The IB is generally seen as more demanding for a mobile child because of its breadth and core, while the Bachillerato concentrates effort on the modalidad and the exam.
Is the Spanish Bachillerato recognised by foreign universities? The Bachillerato with the EBAU mark is the native route into Spanish universities and is accepted by many universities abroad, usually with conversion of the grade and sometimes extra subject requirements. The IB is more strongly recognised internationally, which makes it the safer choice for a family that may apply outside Spain.
Which qualification suits a family staying in Spain long term? For a child most likely to attend a Spanish university, the Bachillerato is the natural and most cost effective route. For a family that may move again or apply abroad, the IB travels more cleanly. Some Spanish schools offer a dual pathway that preserves both.
What is the EBAU or Selectividad? The EBAU, also called the PAU and historically Selectividad, is the Spanish university entrance exam taken after the Bachillerato, usually in June with a second summer sitting. It has a compulsory general phase and an optional specific phase that adds points for competitive courses, and the admission mark combines the Bachillerato record with the exam.
