Learning Study, an enriched version of lesson study, developed during the education reform era in Hong Kong and evolved into a participatory action research model with a theoretical underpinning framework and collaboration between teachers and university researchers. It has once been used as a major model for enhancing partnership between a university and schools for the preparation of pre-service teachers in Hong Kong. In recent years, a shifting focus of this partnership model has been witnessed with recognition of broader needs of schools as well as the accomplishment of a wide range of educational goals including: promoting peer observation through open lessons which serve as a platform for professional exchange; fostering assessment for learning; developing self-directed learning and e-learning strategies, etc.. With the university school collaboration under the Learning Study approach, the value and applicability of the above new initiatives are put into empirical research.This paper reviews the Learning Study programs and projects developed since year 2000 in one of the major teacher training university in Hong Kong, the Education University of Hong Kong. Documents including reports, program books, case studies reports, monographs and related research papers are collected and reviewed in order to identify the challenges encountered and the resolutions found in developing the Learning Study approach in the school community in Hong Kong. Using the framework of Walse & Backe (2013) about the characteristics of effective university-school partnership, this paper analyzes the strategies and critical elements of the Learning Study approach to be developed as a long-lasting and major universityschool partnership model.This paper first illustrates the development of the Learning Study approach in Hong Kong since year 2000 to explicate the shifting focus of university-school partnership - from meeting the need of school placement to accomplish broader education goals by
