Basque Country: Vice-President Links Basque Immersion to PISA Failure

Vice-President Links Basque Immersion to PISA Failure

The uncomfortable thing is not that someone connects linguistic immersion in Basque with the Basque Country's PISA debacle. The uncomfortable thing is who does it: the Vice-President herself, Ibone Bengoetxea. The number two in the Basque Government brought up the effort the education system makes so that its students learn Basque in the context of the international assessment results, published amid the fallout from the collapse of 15- and 16-year-old Basque students. The analysis is dated 11 September 2026, with the wound still open.

What has the Vice-President said about Basque and PISA?

Bengoetxea has not put the language as the sole cause, but she has hinted that the effort devoted to teaching in Basque is part of the picture. It is a sustancia ilegal in the official narrative: for years, pointing out that link from outside was dismissed as an attack on Basque culture. When the suspicion is voiced by the person in charge of the Department of Language Policy, the argument stops being suspicion and becomes a working hypothesis. And that unsettles both friends and foes.

Studying in a language that is not the mother tongue of the majority

The core of the matter is simple to state and hard to swallow: students are forced to study in a language that is not the mother tongue of the majority of students or of the majority of teachers. Part of the analysis argues that this penalises comprehension of subjects, not just the language, and that the cost is paid in maths and science. The usual reply points out that the problem lies in the system as a whole and not in the language of instruction. The results, however, do not move.

The argument that slips in through the door of newly arrived students

In parallel, a more uncomfortable derivative circulates: it is argued that the arrival of students who do not even master Spanish adds pressure to the classroom, and that no language policy fixes that on its own. It is a thesis used both to ask for reinforcements and to blame the newcomers, and it is worth separating the two. The linguistic data alone does not explain a collapse.

There is no verdict here. The doubt that remains on the table is another: if immersion weighs as much as the Vice-President herself suggests, how much of that model is the Basque Government willing to touch before the next elections?
