Located in Jakarta, Mentari operates as part of a network of intercultural schools delivering the International Baccalaureate Primary Years Programme, Middle Years Programme, and Diploma Programme to over 600 students. The school maintains dual accreditation from the Council of International Schools and Western Association of Schools and Colleges, providing international recognition for its educational programs. Campus facilities include swimming pools, gymnasium, football field, science laboratories, art rooms, music facilities, and student lounges supporting both academic and extracurricular activities.

Parent reviews present contrasting perspectives on the school experience. While some families describe positive outcomes with one parent rating their experience as 'fantastic' and expressing satisfaction with their child's progress, other feedback raises concerns about teaching quality and school management practices. The school appears to serve a diverse international community in Jakarta, with Filipino teachers forming part of the faculty roster, though specific demographic breakdowns and academic performance data remain limited in public discussions.

  • Pool of online reviews is small but tilts positive on community feel and pastoral care.
  • Parents describe the school as homey with friendly staff, well-built guidance and counselling, and teachers who extend time for enrichment.
  • IB workload draws complaints from current students. One Indonesian student summed it up as "IB's a bitch."
  • Critical reviews flag uneven academic support, with one ex-student saying late bloomers can be left behind and that some teachers tell pupils to Google answers rather than help.
  • A 2019 New York Times piece, surfaced repeatedly when searching the school, focused on Indonesia's psychological screening of foreign teachers under the 2015 international-school regulation, not Mentari specifically.
