Purpose of the study: This study aims to analyze the influence of student perceptions on academic achievement in Food Microbiology learning at Tan Tao University. Methodology: A quantitative research design was employed involving 80 undergraduate students selected through total sampling. Data were collected using a validated and reliable perception questionnaire, while academic achievement data were obtained from institutional records. Instrument validity was tested using Pearson Product Moment correlation and reliability using Cronbach’s Alpha. Data were analyzed using descriptive statistics and simple linear regression with SPSS at a significance level of 0.05. Main Findings: The results show that student perceptions are generally positive with a mean score of 3.53, while academic achievement is relatively high with a mean of 83.14. Correlation analysis reveals a moderate positive relationship between student perception and academic achievement (r = 0.636). Regression analysis indicates that student perception significantly influences academic achievement, with a coefficient value of 8.02, meaning that improved perception leads to higher academic performance. Novelty/Originality of this study: The novelty of this study lies in its focus on Food Microbiology as a discipline-specific and laboratory-based course in a private university context in Vietnam, where perception is conceptualized as a multidimensional construct shaped by learning experience, lecturer interaction, and laboratory engagement.
