In the 2000s, horizontal governance has become a growing mode of public sector governance. In this study, we examined horizontal governance in the context of career guidance and counselling in Finland. Our empirical research data consisted of ten (10) thematic interviews with public sector officials and other experts working in the governance of guidance at the national level. Our research aim was to scrutinize how the three ideal-types in public sector governance - bureaucratic (Weberian), new public management, and new public governance - were manifested in the informants' discourses. Our results showed that ideologically, there was a shared understanding of the need to increase horizontal governance in guidance. However, in terms of legislation, finance of evaluation of guidance, existing rules and beliefs built in previous ideal-types tend to challenge the implementation of horizontal governance in practice.
