AbstractBackgroundAs we enter the era of milestones and competency‐based medical education (CBME), there is an increasing need to examine the procedures for stratifying objectives into levels of achievement. Most techniques used to date (e.g., Delphi surveys) involve some sort of consensus‐based process, essentially crowd‐sourcing wisdom of multiple educators to set anticipated milestones. In most graduate education settings, however, many simply use the judgment of one or two educators when setting educational objectives. Meanwhile, standard‐setting procedures have been historically used in medical education for setting cut‐points to determine levels of acceptable performance and do so in a more robust manner.ObjectivesInspired by these standard‐setting procedures, the authors sought to develop a new way to stratify objectives into three relative levels of achievement (junior [ACGME level 1], intermediate [ACGME level 2–3], senior [ACGME level 4]).MethodsThe authors describe a novel, stepwise method that is composed of four steps. There are four steps to the McMOST procedure: 1) sorting objectives with a group of experienced teachers, 2) factor analysis to group preferences, 3) labeling components and reorganizing groupings, and 4) confirmation and final review by educational and content experts.ResultsUsing McMOST method resulted in a change of placement for 15 of 34 (44%) of the milestones and improved agreement in two of three levels (intermediate from intraclass correlation of 0.56 to 0.80; senior from 0.69 to 0.79).ConclusionsThe authors describe a novel protocol for stratifying objectives that may be useful to stratify and sort competencies into various levels of achievement (e.g., milestones) in this era of CBME.
