The School Success Profile Learning Organization (SSP-LO) is an assessment tool developed in the United States to measure the capacity of school employees to learn and effectively adopt new practices. This article examines the SSP-LO psychometric properties and evaluates its relevance in Israel. This instrument was administered to 96 employees, consisting of homeroom teachers, teachers, assistants and professionals from three junior high and high schools. The results support the cross-national relevance of the SSP-LO for assessing the capacity of schools to function as learning organizations in Israel. The correlations maintain the internal consistency of items comprising the two learning organization components (that is, actions and sentiments) as well as the four school leadership components (direction, support, learning, and humility). Results from validity analysis show a consistent pattern of positive interrelationships between the scores for learning organization and personal and school outcome components. School leadership components were also significantly correlated with learning organization components. Using SSP-LO results, school social workers are better able to understand and target the school organization as a client system and guide the development of data-informed interventions to create a learning climate that supports evidence-based practice and school improvement.
