To investigate students’ evaluation of teachers’ application of the expectancy effects in ideological and political education courses and its influencing factors in medical universities，a self - designed questionnaire titled“Assessment of Teachers’Use of the Expectancy Effects in Ideological and Political Courses for Students in Medical Universities”was administered to 349 students at a medical university in Jiangsu Province. The results revealed that the overall rating of medical students on the effect of teachers’expectancy effects in class was 3.08±1.48 on a 5-point scale，indicating a moderately high level. Multiple regression analysis revealed that gender，major，political status，and student leadership experience significantly influenced their evaluations（P＜0.05）. Further analysis of student suggestions and expectations highlighted that teaching methods， emotional interaction，and expectation communication also partially affected their assessments. These findings highlighted the importance of actively addressing group disparity among medical students and improving the quality of ideological and political courses in medical universities.
