Research evidence has suggested distributed leadership might help improve school outcomes, but the conceptualization and operationalization of distributed leadership itself remain inconsistent, and the evidence of distributed leadership on many school outcomes is far from complete. This research used the multi-country 2013 Teaching and Learning International Study data to reveal how variations in principal, management team, and teachers' leadership in three primary school leadership functions are associated with teacher professional collaboration, teacher job satisfaction, and teacher organizational commitment. The study investigated multi-dimensional associations using a three-level Structural Equation Model, and found teacher reported shared decision-making was significantly and positively related to all interested outcomes. While using the distributed leadership operational variables, which emphasized the variations in each leader unit's leadership and managerial roles, this study found practically, management team leadership in instructional management and teacher development, and teacher leadership in teacher development were associated with desired teacher collaboration and teacher attitudes.
