Welcome to Seels International Montessori School!

Montessori Approach
Our Montessori classrooms encourage independence, concentration, and a love of learning. Children explore carefully prepared environments where they choose activities, develop problem‑solving skills, and grow at their own pace.
English Immersion & Jolly Phonics
SIMS provides full English immersion, allowing children to absorb the language naturally through daily interaction. The Jolly Phonics program strengthens early reading and pronunciation skills through fun, multi-sensory activities.
Eiken Support
SIMS also offers Eiken preparation for elementary students, helping them strengthen vocabulary, reading, listening, and test‑taking skills in a supportive English environment.
Two Campuses
