QSI International School of Bratislava

What QSI International School of Bratislava does

QSI International School of Bratislava is a private, nonprofit international school operating under the legal entity "Súkromná spojená škola Quality Schools" and governed by the Quality Schools International (QSI) consortium of 37+ schools across 31 countries. Founded in September 1994, the school delivers a full English-language educational program from Early Childhood (ages 2.5-4) through Secondary School (ages 14-18), enrolling approximately 200 students from 32 nationalities and employing 55 full-time faculty drawn from 16 countries. The curriculum is built on QSI's proprietary Mastery Learning and Performance-Based educational model, in which students progress through "Essential Units" at their own pace; mastery is assessed before advancement, and students earn only A or B grades. Secondary students can pursue college-preparatory tracks via the Advanced Placement (AP) Program with 17 AP courses and the AP Capstone Diploma, or the International Baccalaureate (IB) Diploma Programme.

The school operates a direct-to-consumer go-to-market model, accepting rolling admissions year-round with personalized outreach led by the Director. Core revenue is generated from tuition (€9,775 for half-day ECC to €28,275 for full-year 5-18 program), supplemented by a one-time €600 registration fee, a €1,500 annual capital fund fee for older students, and ancillary recurring services including bus transportation (shuttle and door-to-door routes from six locations around Bratislava), a lunch program, after-school activities and athletics, and an annual summer camp. The school is accredited by the Middle States Association (since 1999), authorized as an IB World School, and operates as an official College Board SAT testing center. For the 2026-2027 academic year, the school is relocating from its Samorin/X-Bionic Sphere facility to a new campus at Incheba in central Bratislava.

The customer base is composed of expatriate families, diplomatic personnel, international business professionals, and Slovak families seeking English-medium international education. Distribution is omnichannel: a dedicated website, Facebook, YouTube, Instagram, a Korean-language community page, weekly parent newsletters, an OpenApply admissions portal, and on-campus shadow days. The school maintains small class sizes (approximately 4:1 student-to-faculty ratio), and reports average teacher turnover below 5% annually, with many faculty having authored curriculum for the broader QSI organization.

Broad incumbents

• American International School of Vienna: Large established American international school in the wider CEE/European region offering AP tracks and full K-12 programming. Broader incumbent with deeper history and resources but overlapping target customer base.
• Vienna International School: Major established international school offering IB programmes in a nearby regional market. Broader incumbent competing for the same CEE-based expatriate family segment, particularly families willing to commute or relocate within the region.

Direct peers

• QSI International School of Munich: Sister QSI school in Germany offering the same Mastery Learning philosophy, IB, and AP tracks. Most direct operational and pedagogical comparator, sharing curriculum, governance, and network transfers with QSI Bratislava.
• International School of Bratislava (ISB): Long-established English-medium international school in Bratislava offering IB programmes from Early Years through Diploma. Competes head-to-head with QSI Bratislava for the same expatriate, diplomatic, and affluent local families seeking international credentials.
• Cambridge International School Bratislava: Bratislava-based English-medium school using the Cambridge international curriculum (IGCSE/A-Levels). Targets the same Slovak and international family base as QSI and competes on price/curriculum mix.
• British International School Bratislava: Direct peer serving expatriate and Slovak families in Bratislava with an English-medium curriculum. BISB offers IGCSE/A-Level tracks and competes with QSI for the same diplomatic and corporate family segment in the same city.
• QSI International School of Kyiv: Another QSI-network school delivering the same Mastery Learning and IB/AP programs in CEE. Useful benchmark for curriculum outcomes, faculty practices, and enrollment dynamics across the network.

Others

• OpenApply: Admissions management platform used by QSI Bratislava and many peer international schools. Enabler/ecosystem partner rather than competitor, but represents the technology layer of international school operations.
• College Board: U.S.-based assessment and credentialing body that licenses QSI Bratislava as an AP provider and SAT test center. Ecosystem partner that grants the school's AP/SAT positioning rather than a competitor.

Regional players

• Central European International School (CEIS): CEESA member international school in the CEE region offering IB programmes. Comparable in mission and target segment (expat/diplomatic families) but located in a different market, useful for regional benchmarking.
