The Valenciano Dilemma: How the Regional Language Affects Public and Concertado Education

TL;DR: The valenciano language requirement in public schools across the Valencia region blindsides almost every newly arrived expat family. Public and concertado schools must teach at least 25% of class hours in Valenciano and at least 25% in Castilian (Spanish), with English layered on top. Under the 2025/26 rules, families now get more say over the language balance than before, but Valenciano is not optional in the public system. Here's what it actually means for your child and how to choose.

Most parents moving to the Comunitat Valenciana assume "Spanish school" means school in Spanish. Then their five-year-old comes home reciting numbers in a language that isn't quite the Castilian on their Duolingo app. Welcome to the valenciano language requirement in public schools in the Valencia region, the single most underestimated factor in choosing where your kids study.

This guide explains the linguistic split across public, concertado and private/international schools, what the current plurilingual law requires, and how to make a clear-eyed decision instead of a panicked one.

First, what is Valenciano?

Valenciano is the regional co-official language of the Comunitat Valenciana, linguistically a variety of Catalan, with its own spelling and vocabulary norms. It is not a dialect of Castilian Spanish; it's a separate language. In the public education system it is not merely taught as a subject, it is a language of instruction, meaning maths, science or history may be delivered in Valenciano.

Local reality: How much Valenciano you actually encounter is intensely local. Schools in the city of Valencia and along the coast are often more Castilian-leaning in everyday playground use; schools in inland and smaller-town areas can be heavily Valenciano-speaking, including among the other parents. The legal minimums are the floor, not the ceiling.

The legal framework: what's required in 2025/26

The current model grew out of the regional plurilingual program (the PEPLI framework under Law 4/2018) and was then reshaped by Law 1/2024 on educational freedom, which applies across Infant, Primary, ESO (secondary) and Baccalaureate from the 2025/26 school year.

The core guarantee for public and concertado centres is a minimum balance:

Language	Minimum share of class hours
Valenciano	At least 25%
Castilian (Spanish)	At least 25%
English (foreign language)	Typically ~15-25%

The remaining hours are distributed by the school's language project, and the 2024 reform gives families and communities more influence over how that balance tilts (within the legal minimums) than the previous single-program model did.

Local reality: "At least 25% Valenciano" can in practice be much more, depending on the individual school's proyecto lingüístico (language project) and the historic program it ran. Two public schools in the same district can feel completely different. Before you enrol, ask the school directly: "¿Qué porcentaje de las asignaturas se imparte en valenciano?" and "¿En qué lengua se da matemáticas y ciencias?" Do not rely on the city's general reputation.

How the three systems compare

Public schools

The full requirement applies. Expect a genuine chunk of the curriculum, not only a language class, delivered in Valenciano. State-funded, fast integration, and arguably the best route for young children who absorb both languages effortlessly.

Concertado schools

State-subsidised private schools (often Catholic) are still bound by the same co-official language minimums. Many lean slightly more Castilian in atmosphere, but legally they must hit the Valenciano floor too. Don't assume concertado equals "Spanish-only."

Private / international schools

Here the law works differently: international schools teaching a foreign curriculum (British, American, IB) operate primarily in English, with Castilian Spanish taught as a subject and Valenciano often minimal or optional. This is precisely why expat families pay €6,600-€12,000+ a year, to sidestep the Valenciano-heavy public model. See the full international schools playbook for fees and bus routes.

How to actually make the choice

The Valenciano question usually splits into two honest camps.

Lean into it (public/concertado) if:

• You're staying long-term and want your kids genuinely integrated and bilingual-plus.
• Your children are young (under ~8). They will pick up Valenciano and Castilian without trauma.
• You want to save five figures a year versus international fees.

Sidestep it (private/international) if:

• The move is short-term and curriculum continuity matters more than local integration.
• Your child is an older teen joining mid-secondary, where switching languages of instruction can tank grades during exam years.
• You need an English-medium environment for family reasons.

Local reality: The single most damaging scenario is dropping a 14- or 15-year-old into a heavily Valenciano public secondary right before exams. For young kids it's a superpower; for exam-age teens with no Valenciano, it can be a wall. Match the route to your child's age, not only your budget.

A practical pre-enrolment checklist

• Visit the school and ask for its proyecto lingüístico in writing.
• Confirm the language of instruction for core subjects, not only the headline percentages.
• Talk to other parents at the school gate, the lived reality beats the brochure.
• Cross-reference with your neighbourhood choice; coastal/city barrios and inland towns differ sharply.
