The three tiers of Spanish schooling
Spain's system has three distinct school types and the choice between them shapes the next decade of your child's life. The vast majority of Spanish children attend free public schools; British movers split more evenly across the three tiers.
Public (Colegio Público)
Free, run by the regional education ministry. Curriculum is the Spanish national curriculum delivered in Spanish (with Catalan, Basque, Galician or Valencian as the language of instruction in those regions). For British children under 9, the language acquisition curve is typically fast and full immersion works well. Above 9, the academic load arrives before the language is fully stabilised, which is why many British families with older children skip this tier.
Quality varies more by school than by region — strong individual public schools exist in every Spanish city. Andalucía, Madrid and parts of the Valencian Community now offer formal bilingual public programmes (typically 30-40% of lessons taught in English) which materially smooth the transition for British children. Bilingual programme availability per school is published by each Consejería de Educación.
Concertado (Colegio Concertado)
Semi-private schools that receive state subsidy in exchange for following the public-school curriculum and admission rules. Fees are modest — typically €100 to €500 per month all-in. Around 60% of concertados are Catholic schools (Jesuit, Salesian, Marist orders), with the remainder a mix of secular cooperatives and older religious orders.
For middle-of-the-road British families who want better facilities and smaller classes than typical public schools but can't justify private fees, the concertado is often the sweet spot. Curriculum is Spanish, so the language trade-off remains. Catholic admission preference applies at religious concertados but is usually informal at primary level.
Private (Colegio Privado)
Fully fee-paying, no state subsidy. Encompasses the British-curriculum schools (NABSS network), the international schools (IB, American, French, German), and some elite Spanish-curriculum private schools (e.g. the Madrid “Big Six” — Colegio San Patricio, Liceo Europeo, Runnymede, etc.). Annual fees ranging from roughly €5,000 to €32,000+ depending on school and grade level.
The vast majority of British movers with school-age children end up in this tier — specifically in the NABSS British-curriculum schools — for one reason: continuity of UK academic pathway (GCSE/A-Level), which preserves UK university applications and avoids the Selectividad (Spanish university entrance exam) complexity.
