The project "Corruption in Education", funded by the European Union, and co-funded by the Office for Cooperation with NGOs the Croatian Government, aims to reveal and map out the forms and scope of unethical behaviour and corruptive practices in secondary schools in Croatia. It is being implemented by “Forum za slobodu odgoja” ( and “Network of Education Policy Centers" ( and runs from 5 April 2013 to 4 October 2014. This research project consists of two parts: 1) gathering qualitative information from secondary school pupils, parents of secondary school pupils, secondary school teachers and university students; 2) gathering quantitative data from a representative sample of parents of secondary school pupils and teachers and principals working in secondary schools. Geographical focus is on Split-Dalmatia and Zagreb county as typical developed counties and Sisak-Moslavina and Osijek-Baranja counties as typical less developed counties. This document presents the findings of the quantitative research. Some of the findings show: pupils enrolled into extracurricular activities are the ones who are most commonly given different treatment and are treated better in the City of Zagreb than in other counties, and in gymnasia when compared to other types of schools; gift giving is most common at the end of the school year when gifts given to teachers are not so "innocent", and it seems that it is more common in the more developed counties and in gymnasia; most intensive pressure on teachers to improve marks is coming from parents. It seems that half of secondary school parents in counties that are in focus are familiar with the existence of such pressures, while 60% of teachers and over 90% of principals who took part in research are personally familiar with the existence of such pressures by parents; teachers do recommend private tutoring for their subjects, where 15% of parents have personally witnessed such cases and almost a third of teachers and principals have stated that they are personally familiar with such cases.
