International School Maresme

Small British school in Canet de Mar on the Maresme coast, opened in 2019. English National Curriculum from EYFS through Year 11, with Pearson Edexcel IGCSE at the top end, ages 3 to 16.

The campus sits in a private patch of forest with sea views, which is genuinely unusual and shapes a lot of the day-to-day teaching: outdoor learning is built into the timetable rather than bolted on. The school markets itself as concept-driven and personalised, and at this size it can credibly deliver that.

Independent feedback skews positive on the principal, the teaching team and the small-school feel, with the obvious caveats: a young roll, no Sixth Form yet, and a need for families to plan onward for A-Levels or IB Diploma after Year 11. Fees roughly 7,200 to 11,600 euros put it below the bigger Barcelona names. The right shape for families based north of Barcelona who want a small British primary and lower secondary in walkable distance, rather than the daily commute to BSB Castelldefels or Sitges.

• ISM Maresme is a small British international school in Canet de Mar, founded 2019. National Curriculum of England from Nursery through Year 11 with Pearson Edexcel IGCSEs, set on a campus with private forest and sea views.
• The school's identity is small-scale, Forest School and a family atmosphere. One parent said "small and great school, more like a big family. My kids are happy to go there. They speak english perfectly after just one year."
• Reviews on Barcelona Expat Life and ISchoolAdvisor are short and consistently positive on the principal and individual teachers. One review described "amazing teachers, excellent school principal" and another framed it as "a great small international school."
• A single negative parent review on Barcelona Expat Life simply said "do not recommend at all" with no further detail; the pool is too small to assess what sat behind it.
• International Schools Database notes too few reviews to form an aggregate. Reddit references are about the Maresme region as an expat suburb rather than ISM itself.
• Public signal is too thin for confident generalisation. The visible reviews skew positive on community and language gains, with the negative voice unexplained.
