In 2002, a 6 year review of dental hygiene graduates from the Medical College of Georgia (1996 through 2001) was conducted to determine which criteria were the best predictors of success. Success was defined in terms of National Board Dental Hygiene Examination (NBDHE) score and dental hygiene GPA at graduation. The purpose of this follow-up study was to determine if a relationship exists between predicted success (using 2002 models) and actual success of entry-level baccalaureate degree students who graduated from 2002 through 2007.
Two probability models of success were developed from a previous study of MCG dental hygiene graduates (1996 to 2001). Academic information from students (n=156) in the 2002 to 2007 classes was inserted into the two 2002 models to determine if there was a correlation between their actual and predicted success.
Moderate correlation (r=.581, p=.01) was found when using the established MODEL 1 to predict dental hygiene GPA at graduation and moderate correlation (r=.465, p=.01) was found when using the established MODEL 2 to predict NBDHE scores.
The authors concluded incoming GPA and total SAT((R)) Program score remain useful in predicting the success of students. However, when substituting incoming GPA with dental hygiene GPA at the end of the first year, even stronger correlations resulted in MODEL 1 (r=.957, p=.01) and in MODEL 2 (r=.694, p=.01). Based on these results, recommendations were made to keep current admissions criteria and to implement formal remediation for academically weaker students after completing the first year of the dental hygiene program.
2002年，对佐治亚医学院（1996年至2001年）的口腔卫生专业毕业生进行了为期6年的回顾，以确定哪些标准是成功的最佳预测指标。成功的定义是根据全国口腔卫生委员会考试（NBDHE）成绩和毕业时的口腔卫生专业平均绩点。这项后续研究的目的是确定预测成功（使用2002年模型）与2002年至2007年毕业的本科入门级学生的实际成功之间是否存在关联。
从之前对佐治亚医学院口腔卫生专业毕业生（1996年至2001年）的研究中开发了两个成功概率模型。将2002年至2007年班级学生（n = 156）的学术信息代入这两个2002年模型，以确定他们的实际成功与预测成功之间是否存在相关性。
使用既定的模型1预测毕业时的口腔卫生专业平均绩点时，发现中等相关性（r = 0.581，p = 0.01）；使用既定的模型2预测NBDHE成绩时，发现中等相关性（r = 0.465，p = 0.01）。
作者得出结论，入学平均绩点和SAT（R）项目总分在预测学生成功方面仍然有用。然而，在第一年结束时用口腔卫生专业平均绩点代替入学平均绩点时，模型1（r = 0.957，p = 0.01）和模型2（r = 0.694，p = 0.01）的相关性更强。基于这些结果，建议保留当前的录取标准，并在口腔卫生专业课程的第一年结束后，对学业较弱的学生实施正式的补习。
