Institució La Farga

Boys-only school in Mira-Sol, Sant Cugat, founded in 1969 and run by Institució Familiar d'Educació, an Opus Dei-linked group of thirteen schools across Catalonia and the Balearics. Sister school to La Vall, which takes the girls in the same family network from primary onwards.

Single-sex from primary, Christian identity, and a tutor-led model where each pupil meets a personal tutor twice a month and the family meets the tutor once a term. La Farga teaches the Spanish national curriculum with English support in primary, and offers IB Diploma alongside Spanish Bachillerato in the senior years. Around 1,000 to 1,200 pupils.

The Institució has just stepped back from public concertado funding, alongside La Vall and Les Alzines, to preserve the single-sex model that public funding rules increasingly squeeze. Fees will rise as a result. Families come for the explicit Christian formation, the close family-school partnership, and the academic record into Spanish university. Those uncomfortable with single-sex schooling or Opus Dei will rule it out on principle.

A boys' school in Sant Cugat run by Institució Familiar d'Educació, the Catalan network of schools linked to the Opus Dei prelature. The defining recent story is the move from concertado to fully private from September 2026, taken so the school can keep single-sex classes rather than mix to comply with LOMLOE funding rules. The decision has split the parent body: a vocal minority signed a manifesto asking the school to reverse course, and over a hundred families across La Farga and sister school La Vall began moving children elsewhere during the last pre-registration window. Among the families who stay, the picture is more familiar: warm reviews of teaching and values, criticism for those who feel out of step with the religious frame.
