Our Journey

Intentionally starting small.
Because relationships matter.

We are starting small because depth, trust and culture cannot be retro-fitted later. They must be built into the founding architecture and the hidden culture — with clarity and intention.

Chapter I

Founding Year

  • Two learning studios open in the heart of Cascais.
  • 150 founding learners across three studios, ages 6–14.
  • A highly personalised, deeply known environment.

Chapter II

Inspired IB PYP Inquiry — Candidacy Journey

  • Candidate process initiated before opening day.
  • Professional development aligned to IB standards.
  • Systems, planning and assessment built toward authorisation.

Chapter III

Growing Community

  • Additional studios open with intention.
  • Expanded specialist faculty and outdoor programs.
  • Deep community partnerships across Cascais.

Chapter IV

Full Continuum Vision

  • Primary Years Programme.
  • Middle Years Programme.
  • Careers Programme.
  • A purpose-built campus and global pathways.

A promise

We will grow only as fast as we can remain deeply human.

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.”
