The number of full-time teachers in China's vocational schools increased from 1.11 million in 2020 to 1.29 million in 2021, an increase of 17 percent, providing strong support for the high-quality development of vocational education. In the context of human resource management, the purpose of this quantitative study is to examine the relationship between human resources practices such as information sharing, performance assessment, reward and teacher’ performance for 308 participants in China Shandong Vocational Colleges. Past research seldom researched on the relationship between human resource management practice and teachers’ performance especially in vocational colleges, and there is lack of research about the application of the collegial model in this field. Findings reveal a positive correlation effect between information sharing, performance assessment, and rewards on teachers' performance. Information sharing was found to have the strongest impact on performance. It suggests that the Bush Collegial management model can be applied to improve human resource management and enhance teacher performance in vocational colleges in China. This study recommends that schools create a culture of information sharing, conduct regular performance assessments, and provide incentives in the form of rewards to improve teacher performance, education quality and create a sustainable development in education.
