In this Eye Opener, the authors explore if and how current conceptualizations of validity fit a next era of assessment that prioritizes patient care and learner equity. They posit that health profession education's conceptualization of validity will change in three related but distinct ways. First, consequences of assessment decisions will play a central role in validity arguments. Second, validity evidence regarding impacts of assessment on patients and society will be prioritized. Third, equity will be seen as part of validity rather than an unrelated concept. The authors argue that health professions education has the agency to change its ideology around validity, and to align with values that predominate the next era of assessment such as high-quality care and equity for learners and patients.</p>","PeriodicalId":48532,"journal":{"name":"Perspectives on Medical Education","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11396166/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142298929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, since this research was conducted the publishing landscape has shifted to include a broader variety of journals, an increased threat of predatory journals, and new publishing models.

The authors propose a shift in the design of selection procedures by including additional considerations - student diversity and applicant perception - to select talented students who can fulfil societal needs. The authors explain the importance of incorporating these considerations into the design of selection procedures and challenges that may arise. To overcome the challenges of incorporating student diversity and applicant perception in the design of selection procedures, a new view on alignment between the profession, training and selection is needed. This starts with redefining excellence in the profession with more explicit attention to equity, diversity and inclusion (EDI).
