This work studies syntax in the written papers of secondary school students which were presented on the national festival of literary, performing and journalistic creativity Lidrano 2017 published in the collection LiDraNo 2017. The introductory part deals with mastering syntax in the childhood age and it explains on which level of school (formal) education syntax has been mostly dealt with and at what age a student should be able to master it. The next chapter is about written language and it reviews researches of students' written production. It decribes the smallest measuring syntactic unit as well as its charactristics (T-unit/N-unit). The introductory „theoretical“ part is followed by syntactic division of literary and journalistic papers: it defines average number of sentences as well as lenght of sentences in the students' papers, types of sentences produced by secondary school students and their share in the papers, presence of particular parts of a sentence, synctactic characteristics of the papers considering affiliation to a specific functional style. The results of the research have shown that secondary school students mostly produce complex sentences, among which multiple complex sentences are mostly present. The least present subtypes were simple unexpanded sentences. In these papers more mature language elements are present.
