Ljubljana International School (LIS)

What Ljubljana International School (LIS) does

Ljubljana International School (LIS) is a private PreK-12 international school and kindergarten operating two campuses in Ljubljana, Slovenia — the R5 campus serving PreK through Grade 2, and the S20 campus serving Grade 3 through Grade 12 — together comprising 2,863 sqm of educational facilities. LIS delivers an English-language, American-based curriculum (AERO standards) combined with the full International Baccalaureate continuum (PYP, MYP, DP), and additionally offers the American International High School Diploma and AP Capstone pathway, supported by accreditation from MSA-CESS and membership in CEESA. As of the most recent disclosed figures, the school enrolls 205 students drawn from 35 nationalities, supported by 49 teachers.

The school's core technology is its integrated IB + American curriculum stack and its College Board authorization to deliver AP and SAT exams on-site. Supporting platforms include Toddle (curriculum management), Oxford University Press (educational resources), and NWEA MAP (placement testing). LIS also offers ancillary paid programs — Creative Activities (individual/group music, art, drama), the Intensive English Program, After School Activities (sports, robotics, languages), and a Mother Tongue Language Program — which broaden the offering beyond core academics.

LIS operates a sales-led enrollment motion: prospective families complete an inquiry form, submit documents, pay a one-time non-refundable €1,050 registration fee, take an NWEA MAP placement test, and proceed through admission notification; tours are scheduled via Calendly. Revenue is generated primarily through recurring tuition across the academic year, supplemented by one-time registration fees and unit-priced Creative Activities (€15 per group lesson, €22-€40 per individual lesson). The customer base consists of international and English-speaking families in Slovenia seeking globally recognized qualifications for university placement in Europe, North America, and beyond.
