Clarity International School is a Cambridge primary school for children aged 3 to 12, located in a calm, green neighborhood of Oeiras. It provides a supportive, international environment that combines rigorous academic standards with a focus on individual student growth and wellbeing.
Teaching approach
The educational philosophy is grounded in the belief that children learn best in a calm, respectful, and intellectually stimulating environment. The school emphasizes curiosity, initiative, and responsibility, viewing learning as an active process where students are encouraged to ask questions and take ownership of their education. The approach balances strong academic foundations with a focus on student wellbeing and personal confidence.
Programmes
The school follows the Cambridge International Curriculum, with English as the primary language of instruction and Portuguese taught as a separate subject. The programme is divided into Preschool (ages 3–5), which follows the Early Years Foundation Stage and Cambridge Early Years, and Primary (Years 1–5, ages 6–12), which follows the Cambridge Primary and Cambridge Lower Secondary curricula. Subjects include English, Mathematics, Science, Music, Physical Education, Visual Arts, and Global Perspectives, delivered through project-based learning, research tasks, and teamwork.
Outcomes
The school tracks progress through a transparent system where students complete monthly assessments in key subjects. Every two months, families receive a progress report detailing mastered topics and teacher feedback. In upper primary years (Year 6/Year 8), students participate in formal Cambridge Checkpoint assessments. The curriculum is designed to prepare students for the next stage of education and lifelong learning.
Student support
Learning support
A dedicated child behavior specialist and school psychologist are part of the team to support student wellbeing, social-emotional development, and self-regulation. They provide one-to-one sessions, observations, and practical strategies for teachers and families. During the transition period, the school offers a gradual adaptation process for new students, particularly in the preschool years, with additional guidance and individual meetings.
