The problem was the impacts of the International Baccalaureate (IB) curriculum on Chinese teachers' self-efficacy and student-centered learning practices were unknown. The purpose of this causal-comparative study was to determine the impacts of the International Baccalaureate curriculum on Chinese teachers' reports of self-efficacy and student-centered learning. Two research questions assessed the differences between Chinese IB and public-school teachers for self-efficacy and student-centered learning. The theoretical framework combined Hofstede's cultural dimensions and situated learning theories. Two groups were studied, the first comprised of Chinese public-school teachers who are Chinese nationals, licensed to teach in China, and teach between Grades 1 to 9; the second consisted of IB teachers who met these same criteria but also worked in an authorized IB school and attended at least one IB authorized training. The quota sample, not met for either population, was 385 and 63 respectively. Teacher self-efficacy and student-centered learning practices were measured using the Teachers' Sense of Efficacy Scale, Bandura's Teacher Efficacy Scale, and the Measuring and Improving Student-Centered Learning Toolkit Instructional Staff Survey. A two-sample t-test determined there was a significant difference in self-efficacy levels between IB and public-school Chinese teachers. Post-hoc analysis indicated a medium effect size for self-efficacy regarding classroom management. A two-sample t-test determined there was no statistically significant difference in student-centered learning practice levels between IB and public-school Chinese teachers. The IB impacted Chinese teachers' self-efficacy but not student-centered learning. The IB and Chinese policymakers should further research the impacts of the IB curriculum on Chinese teachers.
