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

Discovery Conversation

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

02

Visit the Studios

An invitation into the space and the people who hold it.

03

Child & Family Profile

We learn about your child as a whole person — not a transcript.

04

Join the Founding Community

A small, deliberate cohort. A founding place at our table.

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: whether this ecosystem genuinely serves the child, the family, and the wider community — over time.”
