Alternative secondary school programmes 

In grammar and vocational schools there are sports programme class departments. Students who are actively engaged in sports and have exceptional results can enrol into sports programme class departments in grammar and vocational schools. Apart from the Sports Grammar School in Zagreb, students can enrol into sports class departments in other secondary schools. The work and classes in these institutions are adapted to the special needs of athletes.

According to the Ordinance on the Elements and Criteria for the Selection of Candidates for Enrolment into 1st Grade of Secondary School the young athletes who are on the ranking lists of a specific national sports association have the right to apply for enrolment into sports class departments. The national sports associations carry out the ranking of the applied candidates based on the sports success criteria. Sports success criteria are determined autonomously for each sport by the appropriate national sports association/federation and are published on their websites and submitted to the Central State Office for Sport. The final ranking list of the candidates is determined by the accumulation of points resulting from the sports success criteria, and the common, additional and special valuation elements.

In secondary schools, part of the curricula and contents determined by the teaching plans and programmes or curriculum, except in the Croatian language, may be taught in one of the world languages, in accordance with the Ordinance on the teaching of part of the subjects and contents determined in the curriculum in one of the world languages in secondary school (OG 116/16).
