III. gimnazija Zagreb

What III. gimnazija Zagreb does

III. gimnazija Zagreb is a public secondary school (gimnazija) located at Kušlanova 52, Zagreb, Croatia, operated under the Croatian Ministry of Science and Education with joint oversight from the City of Zagreb. The institution delivers four-year general secondary education (opća gimnazija) and a specialized mathematics and natural sciences program (prirodoslovno-matematička gimnazija, PMG) that requires candidates to pass an entrance examination. Students are admitted through the national Croatian secondary school enrollment system, and all educational services are provided free of charge.

The school's value proposition centers on academic versatility, offering a broad catalogue of elective subjects across humanities, natural sciences, foreign languages, sports, journalism, and drama, supplemented by extracurricular programs including the Debate Club 'Veritas,' the school newspaper Mi mladi (established 1957), LiDraNo, STEAMBRACE workshops, the Geek Club, and a Health Week. It holds the eTwinning School label and Erasmus+ accreditation, enabling student and staff mobilities across partner schools in Poland, Finland, the Netherlands, Portugal, and Turkey. Digital infrastructure is standard public-sector: a WordPress-based website hosted on CARNET, the e-Dnevnik electronic gradebook for parents and students, and a 360-degree virtual tour via TourMKR.

Financially, III. gimnazija operates as a state-funded institution with no commercial revenue model. Operating budgets come from the Ministry of Science and Education and the City of Zagreb, with supplemental EU structural funds for specific projects. There is no tuition, no product sales, and no disclosed financial figures. The school has produced consistent competition results — including a 1st place at the national history competition, a shared 2nd place at Brain Bee neuroscience, a 5th place at the Hippo English continental round, and a top-16 finish at the Winter Holidays Open international debate tournament — and maintains an active partnership network with the University of Zagreb (Faculty of Economics, Faculty of Medicine), the Croatian National Bank, Instituto Camões, the Geological Institute, and CroAI.
