En Gaztelueta trabajamos para ofrecer una educación en valores

The educational project

Educate upright and autonomous people
Gaztelueta is a charter school of differentiated instruction located in Leioa (Bizkaia) which was founded in 1951 as a result of the concern and social initiative of a group of parents who wanted their children to receive an education centred on individual treatment, respect for freedom and the promotion of personal responsibility, as well as a Christian sense of life.


About us


We believe the best way to carry out a work of human,
intellectual and Christian formation is to carry it out together among families,
teachers and students.


We foster human and civic values that are fundamental to
personal maturity: sincerity, loyalty, justice, a spirit of work, friendship and joy.



All students receive individual and personalized treatment. To this
end, communication with families and their presence at school is essential.


Our educational offer covers all stages: Infant, Primary,
Secondary and High School. Besides, we are an official Cambridge examination centre.

Milestones and traditions

Educar en la fe
Our motto
"Let our yes be yes and our no be no"
The school motto responds to a foundational desire to give special relevance to
the virtues of sincerity and loyalty.
Gaztelueta is a corporate work of Opus Dei, which is exclusively responsible for
Christian orientation. Religious activities are organized for students, teachers
and parents who wish to do so, always on a voluntary basis.
