What teachers and parents say

Positives

  • Accredited IB continuum: Highly regarded as one of the few true non-profit international schools in the city offering full IB programmes (PYP, MYP, DP) with CIS and NEASC accreditations.
  • Attractive compensation and savings: Teachers consistently highlight competitive, tax-free USD salary packages with strong savings potential relative to local living costs.
  • Close-knit school community: Appreciated by parents and staff for its diverse student body, small class sizes, and welcoming, family-oriented environment.

Negatives

  • Extremely high tuition: Frequently cited on local and expat forums as the most expensive school in Ulaanbaatar, making it cost-prohibitive for most families without institutional sponsorship.
  • Harsh climate and severe pollution: Expat staff and families note that extreme winter temperatures, heavy city traffic, and poor seasonal air quality can make daily life challenging.
