The Case for Brutalist Honesty in Medical Education by Markle DT

“…Compared to the past, students now have access to a wealth of outside data to evaluate their curricular progress and career prospects against, and yet institutions are lagging behind in openly disclosing information related to metrics of student success (course passing rates, number of repeat students per class, Step 1 pass rate, etc.) that would engender trust and afford students greater agency in their academic decisions.Approach: In developing a new academic counseling office, the author deployed a method of using brutalist honesty as a means of student support, both in terms of answering all curriculum questions truthfully no matter the topic and with individualized data analytics to provide objective evidence as to student performance progress. …”
