[2][3] The school has been the alma mater of a President of the Basque Government, deputies, mayors of different cities and other politicians and notable alumni.

Everything arose from the initiative of a group of families, who undertook a long journey in the teaching of Basque by their own private homes.

These families wanted to build an innovative educational project, which includes the cultural, social and linguistic values of the Basque Country.

Among the promoters of Basque culture, like Sabin Ipiña, Juantxu Beitia, Alejandro Echevarría, Pablo Escudero, José Miguel de Barandiaran ...[7][8] It began in 1963 with the creation of the Elai-Alai school in Portugalete.

The priest and promoter of Basque folklore and culture, José Miguel de Barandiarán, and Sabin Ipiña were some of the many people involved in the project, they took their first steps in the Francoist Spain, and they have to look for a student in their homes.

That design responded to the intention of combining sport, culture, leisure and education and once approved, the advertising campaign was launched throughout Biscay: "Let's see if we can / Denon artean egiten badogu, danona izango da".

[11][12][13] In 2014, the Town Planning Agreement was signed with the Municipality of Portugalete, for the expansion of Asti-Leku, and the project "Batxilergo Berria / Nuevo bachillerato" was launched.

The school is also the official exam centre of Trinity College London ESOL and Cambridge, as well as numerous other projects.

The school is a reference in Biscay[15] and it is known for its good results and qualifications in Selectividad (similar to the A Level, required for university entrance).
