International Christian School Nonthaburi (ICSN)
Located in Nonthaburi province outside central Bangkok, ICSN follows an American curriculum while integrating Christian values throughout its educational program. The school positions itself as providing 'Bible based community with hands on STEM learning and enriched academics in a suburban Bangkok setting.'
In brief
International Christian School Nonthaburi has run an American-curriculum programme with AP courses since 1997, teaching around 650 pupils aged 3–18 from suburban Nonthaburi, quieter than central Bangkok and read by parents as a feature for younger children. The school holds Thai ONESQA and ACSI accreditation; school director Janwimon (Esther) Ektrakul is part of the founding Ektrakul family.
The Christian ethos is explicit, with Bible classes and chapel central to school life, a draw for families wanting faith-based schooling and less so for those who don't. Parents comparing Nonthaburi options rate ICSN highly, praising large classrooms, outdoor playgrounds and a relaxed teacher tone. One parent who toured several Bangkok-area schools said "we liked ICSN the most by far", pointing to calm older students and teachers who "seemed happy and not stressed out".
Annual fees run from THB 410,700 in kindergarten to 523,200 in the senior grades, well below Bangkok's headline international schools, a gap families cite as a deciding factor. The school cites more than 200 graduates progressing to universities in Thailand and abroad, with steady AP enrolment.

Reviews
- Parents researching Nonthaburi schools rate ICSN highly relative to nearby alternatives, citing space, atmosphere and teacher attitude.
- One parent who toured several Bangkok-area schools said "we liked ICSN the most by far," pointing to large classrooms, calm older students and "teachers seemed happy and not stressed out."
- Fees sit well below the headline Bangkok internationals, which families mention as a deciding factor when comparing with Denla, Ruamrudee Ratchaphruek and others.
- The Christian ethos is explicit (Bible classes, chapel) and is a draw for families wanting that, less so for those who don't.
- The school is suburban and quieter than central Bangkok options, which parents read as a feature for younger children.
Positives
- Value relative to Bangkok internationals. Fees are noted as a fraction of central Bangkok options while delivering an American curriculum and AP track.
- Campus and class environment. Parents praise large classrooms, outdoor playgrounds and a relaxed teacher tone.
- Academic outcomes. School cites over 200 graduates progressing to universities in Thailand and abroad, with steady AP enrolment.
Considerations
- Christian curriculum integration. Bible class and chapel are central; an asset for Christian families and a non-fit for others.
