About
A school with a story — built by someone who has built schools.
ISI Cascais is one of two independent companies founded and led by Nichola de Montaigne — alongside DeMontaigne Life Design. Two distinct organisations. One founding head. One shared compass.
What makes us different
Founded by Nichola de Montaigne.
Built for every child.
Three commitments that bring ISI Cascais and DeMontaigne Life Design together under one roof — and one founding head.
Wellbeing · Belonging
Inclusion Specialists
Two decades in international education, developmental psychology and life design. Neurodiversity, wellbeing and belonging are not add-ons — they are the foundation of how we teach.
Design · Innovation
Individual Pathways
No two children learn alike. Differentiated instruction, formative assessment and flexible grouping mean every learner progresses at their own pace — and on their own pathway from ages 6 to 18+.
WEITS™ Framework
Future-Proof Learning
Wellbeing, Entrepreneurship, Innovation, Technology, Sustainability — the five literacies that travel across unknown futures. Human-led. AI-supported. Concept-based.
Inclusion specialists. Individual pathways. Future-proof learning. Brought together — and built for each child to belong, so the community thrives.
Our standard
We hold one standard.
"Does this genuinely serve the child, the family, and the wider community — over time?"

Founding Head · ISI Cascais & DeMontaigne Life Design
Nichola de Montaigne
British-born in Saudi Arabia, raised in Cascais. Over two decades of international education leadership across Europe, the Middle East, Asia and Latin America.
Master's in International Education and Leadership. Background in Developmental Psychology. Creator of the proprietary PPPP™ and WEITS™ frameworks.
Nichola has spent her career building schools where children are deeply known — and where teachers are trusted, supported and stretched. ISI Cascais is the school she always wanted to build.
"I have spent two decades watching what happens when belonging comes first. Everything else follows."
Two companies · one founding head
A studio, and the ecosystem around it.
ISI Cascais and DeMontaigne Life Design are two separate, independent companies — sharing one founder and one philosophy. ISI is the school. DeMontaigne is the wider ecosystem of family, school and partner consultancy that surrounds it.

PPPP™ · The Compass
How we think.
The proprietary PPPP™ framework — shared with DeMontaigne Life Design — orients every decision we make at ISI: from curriculum to community.
Purpose
What lights you up.
People
Who walks beside you.
Place
Where you feel at home.
Practice
How you show up daily.
From passion to daily practice — a continuous loop, never a checklist.
WEITS™ · Five pillars
What we grow.
Every skill for the future — soft and hard, baked in. The WEITS™ pillars run through the studios at ISI and the ecosystems at DeMontaigne alike.
Wellbeing
Emotional Literacy
How we eat, move, rest & belong.
Entrepreneurship
Financial Literacy
How we take risks & solve real problems.
Innovation
Design Literacy
How we stay curious & adapt to change.
Technology
Digital Literacy
How we connect, create & use AI ethically.
Sustainability
Systems Literacy
How we care for people & planet long-term.

The shift
In a world flooded with information, trust is the currency.
When every child belongs, the community thrives. That is the philosophy — simple, durable, and the lens through which every choice at ISI is made.
