ABSTRACT This longitudinal study aims to create in-depth knowledge about the phenomena of middle-leadership and career in school by identifying (1) driving forces for seeking and maintaining middle-leading positions, (2) opportunities and difficulties in maintaining the middle-leading role over time, and (3) underlying thoughts of career disclosed in the respondents’ expressions. Five different reasons for seeking middle-leading positions are identified and driving forces for maintaining the position are categorised as either internal reward/non-observable outcomes or external reward/observable outcomes. Furthermore, the results show that different types of difficulties arise in distinct phases and that middle-leaders’ needs for support therefore vary over time. Additionally, the complexity of teachers’/middle-leaders’ career thinking clearly emerges, and implications for practice are discussed.

教师领导教师–在分工变化的背景下理解中层领导者的角色和关于职业的想法

摘要这项纵向研究旨在通过确定（1）寻找和保持中层领导职位的驱动力，（2）保持中层领导的机会和困难，来深入了解学校的中层领导和职业现象随着时间的流逝而扮演的角色；以及（3）在受访者的表达方式中揭示的职业基本思想。确定了寻求中层领导职位的五个不同原因，并将维持该职位的动力分为内部奖励/不可观察的结果或外部奖励/可观察的结果。此外，结果表明，在不同的阶段会出现不同类型的困难，因此中层领导者的支持需求会随时间变化。此外，
