Enrollment is now open for the 2026/2027 academic year! Clarity School is a Cambridge primary school (ages 3−11) located in a calm, green neighbourhood of Oeiras — a supportive environment where children grow confident, curious, and truly seen.
Clarity is a school where children truly thrive — a place defined by care, respect, and genuine support.

This is a good school that pays a lot of attention to the quality of education, the atmosphere, and the variety of additional activities. There are after-school and Saturday classes where children can study languages, theater, cooking, reading, etc. The children study in a friendly environment in English. Clarity has already received a Cambridge license. The management has a very good approach to teacher selection - they hire enthusiastic and dedicated people who love children a lot. It's definitely worth adding to the list of schools when choosing a school for your child in Lisbon, Cascais or Oeiras.

We were looking for a school (preschool) that would suit our highly sensitive 5-year-old who didn’t know any languages. Having had a bad experience at another school, we were very sceptical. In the end, we are happy that, by chance, our son is studying here. It is a healthy and free environment where children can develop, learn languages, be themselves, and where they are helped to cope with difficulties. The school promotes a humanistic approach to raising children, and I have never seen any of the horrors that I witnessed at the previous school in just three days. The school has a warm, almost family-like atmosphere. I would like to give a special mention to the preschool teacher Ellis, whom we all adore. But the school is small, so all the staff know every child and are interested in helping them. The preschool has a good balance of learning and play, and no one punishes children for behaving like children. Children in all grades have many fun activities that were not available at school when I was a child. What's more, cool parents choose it for their children, so the fun atmosphere and interesting activities are not only guaranteed for the children :) Of course, there is no such thing as a perfect school, and I could find fault with something here, but at the moment, these advantages are much more important to us and greatly outweigh any possible disadvantages.

A wonderful school with caring teachers and a truly positive atmosphere where our kids quickly started speaking English. The parent community is warm, friendly, and always supportive-it really feels like a big family.
