This study aimed to compare the strength of association (i.e., explained variability) of the cumulative grade point average (GPA) with the grades obtained in the clerkship portfolio and the final structured oral exam by dental students.
A prospective longitudinal study was designed to analyze quantitative data from three cohorts of dental school students. Univariate and multivariate linear regression models were built to evaluate the association between the students' cumulative GPA with the grades obtained in their clerkship portfolio and the final structured oral exam.
In total, 171 students in the last year of the undergraduate program were considered (76% women, age average 24.8 ± 1.6 years). The dental students' grades of both portfolio and structured oral exam were significantly associated with the GPA score but with different strengths of association. The clerkship portfolio was more strongly associated with cumulative GPA than the structured oral exam (R = 19.6% versus R = 7.6%). On the opposite, the association between the structured oral exam and GPA can be interpreted as a lower precision in its practical significance and thus reflecting different concurrent validity.
Considering the results of this study, it could probably incline the balance toward the portfolio because it may be closer to a programmatic assessment model, with timely feedback, development of metacognition, and the achievement of formative process measurement rather than evidence of a single instance of examination.
本研究旨在比较牙科学学生的累积平均绩点（GPA）与临床实习档案成绩和最终结构化口试成绩之间的关联强度（即解释变异度）。
设计一项前瞻性纵向研究，以分析来自三个牙科学院学生队列的定量数据。构建单变量和多变量线性回归模型，以评估学生累积GPA与临床实习档案成绩和最终结构化口试成绩之间的关联。
总共纳入了本科课程最后一年的171名学生（76%为女性，平均年龄24.8±1.6岁）。牙科学学生的档案成绩和结构化口试成绩均与GPA得分显著相关，但关联强度不同。临床实习档案与累积GPA的关联比结构化口试更强（R = 19.6%对R = 7.6%）。相反，结构化口试与GPA之间的关联在实际意义上的精度较低，因此反映出不同的同时效度。
考虑到本研究的结果，可能会使天平倾向于临床实习档案，因为它可能更接近一种程序性评估模式，具有及时反馈、元认知发展以及形成性过程测量的实现，而不是单次考试的证据。
