Making the case for pass-fail grading in dental education

Building a student learning-focused assessment and grading system in dental school: One school's experience

PURPOSE/OBJECTIVES

As health professions education moves toward competency-based education, there has been increased focus on the structure of assessment systems that support student competency development and learning. This has been buoyed by a growing body of research supporting assessment for learning processes to promote student growth and learning rather than relying on assessment systems primarily to measure performance. This paper presents the rationale and evidence for moving to an assessment for learning system and the results of a quasi-experimental interrupted time series study using data from 2015 to 2022 to evaluate the impacts of these changes.

METHODS

Columbia University College of Dental Medicine faculty voted to implement assessment for learning system changes beginning in 2017 with the graduating class of 2021. These changes included moving from using a grading system for didactic courses with Honors, Pass, and Fail as available grades to a grading system with only Pass and Fail as available grades, as well as creating synthesis and assessment weeks, weekly problem sets, post-exam review sessions, exam remediation opportunities, and formative progress exams throughout the curriculum. The revised assessment and grading system changes were communicated to residency program directors, and programmatic competency data about student performance across the curriculum were shared with programs in Dean's Letters.

RESULTS

Once assessment system changes were implemented, it was found that student exam failure rates were lower, course exam scores were the same or higher, and performance on board exams improved compared to the national average. Students reported positive perceptions with regard to well-being and learning climate that they associated with the adoption of Pass/Fail grading. Match outcomes, including student satisfaction and program director ratings, have remained consistently positive.

CONCLUSION

As dental educators, our goal is to nurture students to become life-long learners. Adopting a grading structure that is Pass/Fail and an assessment system that fosters learning allows students to shape learning practices that favor long-term retention and application of information, also enhancing the learning environment and student well-being. These system changes may also facilitate the inclusion and support of students whose backgrounds are underrepresented in dentistry.

Deficiencies of Traditional Grading Systems and Recommendations for the Future

Objective. To review issues surrounding the use of grades in the educational process and provide evidence-based recommendations for how to redesign grading practices for optimal value.Findings. Traditional tiered grading systems (ie, A, B, C, etc) have historically been a major component of the formal educational process. The way grades are used and interpreted are typically based on some commonly held assumptions, including that they are accurate measures of learning, that they motivate students to learn, and that they provide feedback to learners. However, much of the research regarding grades indicates that flaws exist in these assumptions. Grades may not always accurately measure learning, they can have adverse effects on student motivation, and they are not a good form of feedback.Summary. The Academy should consider the evidence regarding the purpose, effects, and interpretation of grades in the educational process. Despite barriers and potential pushback, pharmacy educators should revise grading practices to be more accurate, interpretable, and beneficial to learner development.

Use of a Knowledge-Based Governance Approach to Plan a Post-COVID-19 Predoctoral Dental

COVID-19 abruptly changed dental education, forcing educators out of their comfort zones and into using new technologies and teaching approaches. At the University of Washington School of Dentistry, a task force evaluated the curricular changes that resulted from COVID and made recommendations for the future predoctoral dental curriculum. This manuscript reports the process employed, the findings of the task force, and how these findings will impact the curriculum. A knowledge-based governance (KBG) approach was employed. KBG focuses on gathering all relevant information and identifying all choices. It separates dialogue from deliberation. Information was gathered via literature review, focus group interviews, electronic surveys, and other metrics. The task force evaluated: (1) delivering didactic content remotely; (2) administering assessments remotely; (3) duplicating preclinical simulation lab courses due to social distancing; and (4) the conversion from a numerical to a credit/no credit grading scale. Key recommendations resulted from focus groups and electronic surveys that allowed any student or faculty member an opportunity to provide input. Some topics were relatively non-controversial and strong recommendations were evident. The most controversial issue was which grading scale should be utilized. A KBG approach is an effective means to address mega issues in the dental school environment.
