Six-year-olds across the Western Balkans started their first day at osnovno učilište last September. Their parents filled out enrollment forms in February, chose between religious instruction or ethics classes, and wondered whether the eight-year system their children just entered looks anything like the schools they remember from the 1990s.
It doesn’t.

What Osnovno Škola Covers Across Six Countries
Primary schools operating under the osnovno učilište model span Croatia, Serbia, Bosnia and Herzegovina, Montenegro, North Macedonia, and Slovenia. The term translates directly to elementary or basic school. These institutions handle compulsory education from age six through fifteen.
Governments fund public schools completely. Parents pay nothing for tuition, though private alternatives exist in larger cities like Belgrade, Zagreb, and Skopje.
The Croatian Ministry of Science, Education and Youth reported operating 2,057 elementary schools during the 2024/2025 academic year. Serbia’s Ministry of Education oversees roughly 1,200 primary institutions. Both countries inherited their educational frameworks from Yugoslavia but have spent three decades adjusting them.
Eight Years, Two Distinct Phases
Lower elementary runs from first through fourth grade. One teacher handles most subjects in a single classroom. Students learn basic literacy, mathematics, and foundational skills. English instruction begins immediately in first grade under specialized language teachers. Physical education, art, and music round out the schedule.
Upper elementary splits instruction across subject specialists. Fifth through eighth graders move between classrooms for Croatian or Serbian language, mathematics, history, geography, biology, chemistry, physics, and foreign languages. Class sizes hover between 15 and 28 students, randomly assigned weeks before the academic year starts in September.
Schools operate five days weekly. Morning shifts run 8:00 AM to 1:10 PM, afternoon shifts 1:15 PM to 6:20 PM. Classes rotate between morning and afternoon schedules weekly.
The Grading System Parents Need to Decode
Both Serbia and Croatia use numerical assessment:
5 (odličan) = excellent
4 (vrlo dobar) = very good
3 (dobar) = good
2 (dovoljan) = sufficient
1 (nedovoljan) = fail
First graders receive written evaluations instead of numbers. Teachers describe each child’s development across subject areas without numerical grades.
Final marks don’t calculate as straight averages. Teachers weight improvement and effort when determining end-of-year grades. A student showing consistent growth might receive a higher final grade than their numerical average suggests.
Slovenia follows similar patterns but uses its own terminology. North Macedonia issues completion certificates after eighth grade labeled “svidetelstvo za završeno osnovno obrazovanie.”
How Full-Day Schools Changed Everything in 2023
Croatia rolled out experimental full-day programming across select schools two years ago. The Eksperimentalni program Osnovna škola kao cjelodnevna škola extended hours to 3:30 PM and restructured how students spend their time.
Regular instruction now includes supervised homework sessions, recreational activities, and structured afternoon programs. The government increased Croatian language and mathematics instruction by one weekly hour after international assessments showed literacy and numeracy gaps.
Schools added tablets and expanded WiFi networks. Zagreb institutions installed desktop computers and projectors in every classroom. Older buildings struggled with electrical infrastructure unable to support digital equipment.
The reforms target 309,000 elementary students currently enrolled across Croatia. Not every school participates yet. Parents in participating districts can opt out and maintain traditional half-day schedules.
Getting Children Enrolled Takes Planning
Enrollment windows open each February for September admission. Parents register at their residential district’s assigned public school. Selecting a different school requires written consent from that institution.
Children must turn six during the calendar year they enroll. Early admission exists for students born before March, allowing them to start at age five if parents request it and the child passes readiness assessments.
Schools issue enrollment certificates three months before classes begin. Documentation requirements include birth certificates, residency proof, and health records showing completed vaccinations.
Extended-Stay Options Beyond Regular Hours
Produženi boravak programs let students remain at school until 5:00 PM. Working parents use these services when jobs prevent afternoon pickups. Children receive supervision, snacks, and time for homework completion.
Full-day programs go further. Students stay until 3:30 PM with structured afternoon lessons, recreation, and meals. Schools charge fees for lunch service. Extended-stay supervision remains separate from full-day programming.
Bilingual tracks teach core subjects in Serbian or Croatian plus English, French, German, or Italian. International schools serving expatriate families operate in capital cities but charge tuition.
The Rural School Crisis Nobody’s Solving
Osnovna škola Sveti Petar Orehovec enrolled 904 students in 1980. Current enrollment sits at 300. The school operates four satellite campuses in surrounding villages, some teaching multiple grades in single classrooms.
Demographics drive the collapse. Young families moved to cities during the 1990s and never returned. Villages across Croatia and Serbia face identical problems. Small schools lack resources for specialized teachers, modern equipment, or facility maintenance.
Some rural schools will close. Officials haven’t determined which ones or when. Parents in affected areas will need to arrange transportation to consolidated schools in larger towns.
What Schools Actually Need Right Now
Infrastructure remains the biggest gap. Many buildings date to the 1960s and 1970s. Libraries fall below recommended space standards. Multi-purpose rooms for assemblies don’t exist in older construction. Energy efficiency upgrades move slowly through municipal budgets.
Teaching staff shortages hit rural and urban schools differently. Villages can’t fill positions. Cities deal with overcrowded classrooms when enrollment exceeds building capacity.
Technology integration continues unevenly. Schools that received equipment during recent reforms still need teacher training on educational software and digital pedagogy. Equipment sits unused when staff lack implementation knowledge.
Understanding The System That Shapes Everything After
Osnovno učilište builds the foundation for secondary education and university admission. Performance during these eight years determines which gimnazija or vocational schools accept students at fifteen. The compulsory elementary phase remains free, universal, and surprisingly consistent across countries that separated three decades ago.
Parents navigating enrollment for the first time face a system that looks familiar on paper but operates differently than it did a generation ago. The schools their children attend now spend more time teaching English than their grandparents spent learning it across their entire education. Classrooms have tablets that didn’t exist ten years ago. Teachers follow curriculum standards aligned with European Union frameworks instead of Yugoslav educational planning.
The basics stay the same. Children enter at six, spend eight years learning, and leave ready for whatever comes next. How schools deliver that education keeps changing.
