Data description | Statistics on basic and secondary education provide data on educational activity in all types of schools. Main units of the survey are students (new entrants and graduates) and teaching staff. The main indicators for which data is collected on enrolled students include: sex, year of birth, grade, educational level, form of study, characteristics of the school (type, location, and type of ownership), as well as the profession/specialty studied. Until the 2020/2021 school year (incl.), the source of the data was the educational institutions themselves, which annually completed the ‘Report on Schools’ as of October 1 of the respective year. Starting from the 2021/2022 school year, the source of the data is the National Electronic Information System for Preschool and School Education. The observation date for the 2021/2022 and 2022/2023 school years is December 1, and from the 2023/2024 school year onwards – December 31. |

Statistical concepts and definitions | A pupil/student is every person enrolled in an educational program of formal education according to ISCED irrespective of the mode of attendance. Formal education includes the educational programmes implement in the legitimate educational institutions created according to the existing legal order. Newly enrolled pupils/students - pupils/students who have been enrolled for the first time in the initial grade or course of the respective educational level are considered newly enrolled. This means that those which have been enrolled in the same educational level previous years are not included to the number of the newly enrolled. Graduates are those pupils/students who have received a document for a completed level from a legitimate education institution, containing all the necessary records and stamps according to the law. Students who have left school are defined as students who were enrolled in the beginning of the previous school year but before its end due to some of the listed reasons had left the school. Those who have left school cannot be treated as dropouts from the educational system because they could continue their education during the next school year and those who were under 16 years of age are obliged to continue their education. Data on left students are available up to the 2019/2020 school year, due to lack of information about them in the administrative registers of the Ministry of Education and Science. The teachers are official persons who directly conduct the training sessions according to curriculum irrespective of whether they are full or part time employees. Directors and assistant directors are observed separately although a great part of them may have lecturing functions as well. An educational institution is defined as a centre taking independent decisions, which performs educational services for persons and organizations and is created according to the rules of the law. This means that the institution has a manager (director, rector or another manager) i.e. that this is an 'independent' educational institution. 'Dependent' educational institutions are branches or units known under other names and are typically subordinate to an independent institution. When determining the number of schools, only independent institutions are included, without their branches. Depending on the type of programme in which they are enrolled, students are classified into the following groups: those studying in general education programmes, those studying in special programmes, and those studying in vocational programmes. Vocational programmes include students who are enrolled in a specialty/profession listed in the Register of Professions for Vocational Education and Training. Special programmes include students attending special schools. All remaining students are classified in general education programmes. According to the type of ownership, schools are divided into public and private. The group of public schools includes all state and municipal schools, while the group of private schools includes all private and spiritual schools. |
