Global Indian International School (GIIS).

Where this school stops

This is Pathum Thani’s first question, not its last. Three of the province’s eight schools end at roughly age eleven — including two of the best-known names in the AIT and Thammasat corridor.

Class 12, roughly age 18 -- a complete pathway to an Indian board qualification on one campus.

Where the campus actually is

39/39 Moo 1, Soi Watchinwararam, Pathum Thani-Sai Nai Road, Bang Khayaeng, Mueang Pathum Thani District, Pathum Thani

A large riverside campus in Bang Khayaeng, reached by road. It is closer to Mueang Pathum Thani's administrative centre than to Rangsit's condo belt.

Rail: today, and in 2029

The SRT Dark Red Line currently terminates at Rangsit. Contracts for the 8.84 km extension to Thammasat University’s Rangsit campus — four stations at Khlong Nueng, Bangkok University, Chiang Rak and Thammasat University Rangsit Campus — were signed in May 2026, with construction expected to start in July 2026 and service targeted for 2029.

Not on any current or planned rail. Bang Khayaeng sits on the Chao Phraya west of the Phahonyothin corridor; none of the four Red Line Phase II stations serves it.

The curriculum pathway, stage by stage

• Early years -- the group's Global Montessori Plus programme.
• Classes 1 to 12 -- the Central Board of Secondary Education (CBSE) curriculum of India.
• Entry from Class 1 upward is by written entrance examination.

Accreditations & authorisations

Worth separating: an examination-board authorisation (Cambridge, IB, CBSE, College Board) means a school may enter pupils for those exams. A whole-school accreditation (WASC, CIS, COBIS, Cognia, ISQM) assesses the school itself. Both matter; they are not the same claim — and an accreditation can cover only part of a school’s year range.

• Central Board of Secondary Education (CBSE), India -- GIIS is reported to be the only school in Thailand delivering the CBSE curriculum.
• Operated by the Five Pillar Education Trust.
• We could not verify a separate whole-school international accreditation from the school's own primary pages, and do not assert one.

Religious character

None published as a requirement. The school presents itself as an independent co-educational school; we found no statement of faith or compulsory religious studies condition.

Boarding

None advertised at the Bangkok/Pathum Thani campus.

Who it suits

Indian and South Asian families who need curriculum continuity with India, and any family who specifically wants a CBSE pathway -- for which this is, on current information, the only option in the country. Facilities reported include science laboratories, a library, theatre, yoga studio, auditorium, cricket ground and badminton courts.

What we could not verify — and where sources disagree

We publish these openly rather than smoothing them over. A school guide that hides its uncertainty is not much use to a family making a decision this big.

• The single most useful fact about GIIS is one no other school here shares: in line with the Indian curriculum, ITS SCHOOL YEAR RUNS APRIL TO APRIL, not August to June. Every other school in this guide starts in August. Transferring in either direction across that boundary costs a child roughly half a year, and no directory listing makes this obvious.
• The school is named and marketed for Bangkok and every directory files it under Bangkok, but the campus is in Mueang Pathum Thani district, Pathum Thani province. This is the province-is-not-city trap running in reverse -- and it is precisely why the school was missing from BAANLYY's Pathum Thani page.
• Entry from Class 1 is by written entrance examination. That is a real admissions gate, not a formality, and it should be planned for.
• Detailed facility and fee claims circulate mainly through third-party directories rather than the school's own primary pages. We publish structure and location, and no fee figures.

Ask every Pathum Thani school this

• Does this school go as far as your child needs -- or is it a staging post? Three of the province's eight schools stop at roughly age 11, including the two best-known names in the AIT and Thammasat corridor. If your child is nine, you are choosing two schools, not one. Ask which schools families here typically move on to, and whether the school helps with that transfer.
• Ask about rail in two tenses. Today the Red Line terminates at Rangsit and no Pathum Thani campus has a station. Contracts for the extension to Thammasat Rangsit -- with a station at Khlong Nueng -- were signed in May 2026, with service targeted for 2029. Whether that is relevant to you depends entirely on how long you are staying.
• Check what the school year actually is. Global Indian International School runs an April-to-April Indian academic year; every other school here runs an August start. Moving mid-cycle between the two costs a child half a year in either direction.
• Is the accreditation whole-school, or is it an examination-board authorisation, and does it cover the year group your child is entering? Thai International School's WASC accreditation is stated by the school as covering Nursery to Grade 6 -- so a programme above that line is not inside the same claim.
• Is it a school, or a programme inside a school? The Invictus International Programme is an international pathway delivered within Sathitpathum Demonstration School, not a standalone international campus. That is a real and legitimate model, and it is not the same thing a directory listing implies.
• Drive the run at 07:00 on a weekday before you sign a lease. Phahonyothin, Rangsit-Nakhon Nayok Road and the Rangsit junction at rush hour bear no relation to the same roads at midday, and Pathum Thani's school geography is spread across four districts.
• Ask what the year group's actual size is this year, not the school's total roll. Several schools here are small by design, which many families want -- but you should know the number before you decide.
• If faith or national curriculum matters to you in either direction, ask directly. Pathum Thani's eight schools include British, American, IB, Indian CBSE, Cambridge-bilingual and Thai-bilingual routes, and they are not interchangeable.
