Great International School

What Great International School does

Great International School (operationally branded Great School) is a private bilingual K-12 school founded in 2021 and headquartered in Teresina, Piauí, Brazil. It operates a single 55,000 m² campus on the site of the historic Jockey Club and serves students from ages 2 through 17 across four segments: Early Childhood (Educação Infantil, K1-K5), Elementary (Ensino Fundamental anos iniciais, Grades 1-5), Middle School (Ensino Fundamental anos finais, Grades 6-8), and High School (Ensino Médio, Grades 9-12). The school is the only institution in Piauí state to simultaneously hold three international accreditations: the International Baccalaureate (IB) Diploma Programme, the International Curriculum Association (IEYC/IPC/IMYC) curricula, and the UNESCO Associated Schools Network membership.

The school's core technology is a bilingual immersion platform integrating the Brazilian national curriculum (BNCC) with international frameworks. The pedagogical architecture follows structured English exposure: 70% English immersion for ages 2-3, 50% for ages 4 through Elementary, and itinerary-dependent exposure in High School. Supporting programs include the EAL (English as an Additional Language) push-in/pull-out model for non-English-entering students, and an online Student Portal (portalpensar.app.br). The High School segment adds the IB Diploma Programme with its three core components (Theory of Knowledge, Extended Essay, and CAS) and offers college counseling, SAT/ACT prep, and Cambridge certification pathways.

The business model is tuition-based subscription recurring revenue, billed annually for full-time in-person education. Pricing is quote-based and not publicly disclosed. Go-to-market is direct-to-consumer: families inquire via the school's website (greatschool.com.br), WhatsApp, or campus visits; marketing combines digital channels (website, social media), traditional local media (newspaper, radio, magazine, flyers), school guide listings, and word-of-mouth referrals. The school is founder-controlled by Vilton Soares, who is also Director of Grupo Pensar Educação, a network of excellence schools in Piauí and Maranhão. No external institutional investors, PE/VC backers, or M&A activity are disclosed.
