In this article we discuss multi-level career paths of Czech politicians from 2000 to 2017. First, we describe typical career movements between policy levels, differentiating between ascending and descending paths. Subsequently, we focus on ascending paths targeting at the national level which are the most common way how to enter the Parliament. Using a complex interlinked database of candidates in individual local, regional and national elections, we find that the Czech political system is dominated by ascending career paths. One of their important effects is increasing underrepresentation of women at the national policy level.
