Admissions

Finding the right fit matters.

Admissions at ISI are relational, not transactional. We take time to understand every child and family, because belonging begins long before the first day.

Our process

Four chapters. One conversation.

01

A relaxed call. We listen, you ask, we explore fit together.

How we measure our success

Academic excellence.
Never compromised.

We can only learn when we are willing to take risks, and we can only take risks when we feel confident and known. That is why belonging and rigour are not opposites at ISI. Academic excellence is a key driving indicator of how we measure our success as a community.

Curiosity is what we light first. Our unique PPPP™ compass, Purpose, People, Place and Practice, is how we keep learning relevant, meaningful, significant and challenging for every child, so rigour is felt as wonder, and challenge becomes something children learn to meet with growing skill, stamina and confidence.

01

Rigour, never compromised

High expectations in literacy, numeracy and conceptual understanding for every child, assessed against international IB-aligned standards and tracked with evidence over time.

02

Strengths first

We begin with what a child can already do. Strengths-based teaching is linked to higher engagement, persistence and achievement, so we build from strength towards stretch.

03

Courage to take risks

Learning happens at the edge of what we know. Children who feel safe to be wrong attempt harder problems, and mistakes become information, not judgement.

04

Confident lifelong learners

Self-efficacy is one of the strongest predictors of achievement. We measure growth in what each child can do, and in how confidently they choose to keep learning.

Our Mission

When the Child Belongs, the Community Thrives.

Three commitments

Three commitments that bring ISI Cascais and DeMontaigne Life Design together.

“We hold one standard above all others: that every child belongs, deeply, visibly, and before anything else is asked of them. Three studios, flexible ages, one question that guides every decision: does this genuinely serve the child, the family, and the wider community, over time?”
