Purpose: This study aimed to explore the relationship between the psycho-social working conditions of novice school leaders and their turnover intentions, focusing on potential variations across public- and private schools and school levels. Research Methods: We invited all novice school leaders (n = 3,389) enrolled in the in-service Swedish Principal Training Program to participate in an extensive survey, with a 65% (n = 1,998) response rate. The survey investigated turnover intentions, working conditions, prerequisites, and organizational ambiguity. The collected survey data, in combination with official data, were analyzed using ANOVA's to identify differences across actors and school levels, and linear regressions to investigate factors explaining turnover intentions. Findings: The findings revealed higher turnover intentions among public school leaders compared to private school leaders. This was attributed to differences in prerequisites and organizational ambiguity. All novice school leaders exhibited similar patterns regarding factors strongly associated with turnover intention, despite actor and school level affiliation. Specific levels of demand, autonomy, and support combined, predicted turnover intentions among novice school leaders with notable accuracy. Implications for Research and Practice: The study has profound implications for stakeholders in the educational system striving to decrease novice school leader turnover. Providing adequate working conditions emerges as a key factor for nurturing and retaining school leaders from the novice pool, offering insights into strategies for managing leadership transition in schools.
