CAISL Elementary School is the primary stage of one of the longest established international schools in the region, and a useful entry point to weigh against the other options on our Lisbon city hub. It delivers the American elementary curriculum in English on the Carlucci campus at Linho, between Sintra and Cascais, the same site that runs all the way to grade 12. For families moving with younger children, the appeal is the continuity: a child can settle into the elementary years knowing the middle school, high school and the senior American and IB pathways sit on the same campus.
This profile is an independent reference page. GlobalSchoolGuide does not rank schools for payment and no school appears here because it paid to. We researched the facts below from the school and public sources at the time of writing and flag anything we could not confirm as not published.
At a glance
Curriculum and academics
The elementary years deliver an American style primary curriculum in English, building literacy, numeracy and inquiry through the early grades with the breadth of arts, physical education and specialist teaching typical of a large international school. Because the elementary division sits inside an authorised IB World School, the learning culture is shaped by the same standards that carry through to the IB Diploma in the senior years, even though the formal Diploma programme begins much later.
The real advantage for younger children is the unbroken path. A child who starts in the elementary grades does not face a change of school to reach the middle and high school stages; they progress on the same Linho campus toward the American High School Diploma, Advanced Placement and the IB Diploma. Families weighing where the elementary route eventually leads can read our IB curriculum guide to understand the senior Diploma their child could reach without ever moving schools.

CAISL Elementary School fees
Elementary tuition sits below the secondary and IB Diploma rates, as it does at most through schools, but still in the upper part of the Lisbon market in line with the larger established internationals. The school publishes a current fee schedule by grade, so treat any number as one that changes each academic year and confirm the latest elementary figure directly, then compare it with the bands in our Lisbon international school fees guide to see where the primary years fall against the rest of the city.
Budget beyond tuition. Expect a registration or application fee and a deposit to secure a place, and factor in the school bus network covering Cascais, Estoril, Lisbon and the surrounding areas, which is a meaningful cost given the Linho location. Lunch, trips and activities add to the annual bill in the elementary years too. Ask how fees are staged across the year and use our fee tools to model the full cost before you commit.
Admissions
The elementary division admits for an August or September start and reviews applications throughout the year subject to space, which suits families who arrive in Lisbon mid term. Entry for younger children usually rests on prior school records and a readiness assessment rather than a formal examination, with the school placing each child in the right grade within the American system.
Elementary grades are popular at a school of this size and reputation, so waiting lists can form in over subscribed year groups. Families planning a move should apply early, ask directly about availability in their child's grade, and confirm what the school needs to assess a younger child joining partway through the primary years.
Location and who goes there
The elementary division shares the Carlucci campus at Linho, between Sintra and Cascais, to the west of central Lisbon. The bus network across Cascais, Estoril, Lisbon and the surrounding areas widens the practical catchment well beyond the immediate neighbourhood, so elementary families come from across the coastal belt and the city rather than only from the villages near the campus.
The community is broadly international, reflecting the school's history as the State Department sponsored institution, with American, Portuguese, Brazilian, Chinese and many other families among the youngest year groups. For the wider picture of who settles where across the region, see the Lisbon city hub, which maps the neighbourhoods and the schools that serve them.
