However, it can be said that the literature contains a limited number of measurement tools that allow for the evaluation of school principals' leadership practices, and that these tools address leadership practices within a narrow scope. For this reason, the purpose of the research conducted is to present the development process of the School Leadership Practices Scale(SLPS), which function of making sense of school principals’ leadership practices based on teachers’ perceptions. The measurement tool was developed in four stages: generation of the item pool; ensuring content validity; conducting a pilot study; and verifying the structure of the vehicle with the actual application. The sample of the study consisted of teachers working at the secondary school level. Exploratory factor analysis reveals that the total variance explained is 65.06%. When the absolute fit indices are evaluated as a whole, it is concluded that the developed measurement model provides a high level of fit to the data. CR values (.90-.93) indicate that all dimensions exhibit high levels of reliability. Upon the confirmation of the instrument's structure, a multidimensional model is identified, which measures school principals’ leadership practices through 35 items under five factors: (a) professional ethics; (b) strategic management; (c) personal leadership resources; (d) change and data-based school development; and (e) a safe and supportive school climate. </style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Research article </style></work-type><section><style face="normal" font="default" size="100%">327-345</style></section></record></records></xml>
