History and Founders

Founders

Nattalia Sinclaire & I Made Wiranatha “Pak Kadek”

Nattalia Sinclaire was born in Ireland to Irish and Canadian parents and later made Bali her home, becoming an Indonesian citizen after her marriage to Kadek. United by a shared vision for children and education, Nattalia and Kadek founded Montessori School Bali in 1998. With AMI Montessori diplomas for ages 3 to 12, Nattalia brings deep pedagogical knowledge and a lifelong commitment to Montessori principles. More than 25 years on, Montessori School Bali remains the only Balinese family-owned, AMI-affiliated and Indonesian-accredited international school on the island, continuing to grow with the same care, integrity, and sense of family with which it began.

Dr Maria Montessori's Vision

The Three-Period Lesson

A unique system used to evaluate student progress

First Period

Introduction

Introducing new concepts to students in a clear and engaging manner

Second Period

Recognation

Prompting students to recognize and identify the concepts taught

Third Period

Confirmation

Confirming authentic evidence of learning through questions

Continual monitoring of students allows Montessori trained guides to know when to redirect individual students to areas where they can repeat a lesson or work with classmates that are familiar with the concept.
