The purpose of the statistical survey is to collect individual data on enrolment of students in higher vocational and higher undergraduate and postgraduate studies taking place at public and private vocational colleges and public and private higher education institutions. The survey covers the fields of post-secondary (tertiary) education, and undergraduate and postgraduate (higher vocational, professional higher, academic higher, master’s, specialist and doctoral) studies. Observation units are students in vocational colleges and higher education institutions. Data on enrolment of students in vocational colleges and higher education institutions are collected with the regular annual statistical survey. There are two sources for these data: the ŠOL-ŠTUD questionnaire (filled in by students in vocational colleges and single higher education institutions) and the Matriculation Document (filled in by higher education students). The ŠOL-ŠTUD questionnaire is designed on the basis of the Matriculation Document. The Matriculation Document or the ŠOL-ŠTUD questionnaire are filled in by full-time and part-time students at the enrolment in the first year of studies, all other years of studies, when they become candidates for graduation as well as if they repeat a year. Coverage is full, which means that the survey covers all students in all vocational colleges and higher education institutions in the country; this is a census of all students who are in a specific academic year (e.g. 2009/10) enrolled in vocational colleges or higher education institutions. The data are collected and published as of 15 October.
