Introduction: The field of medicine is characterized by within-field gender segregation: Gender ratios vary systematically by subdisciplines. This segregation might be, in part, due to gender bias in the assessment of women and men medical doctors.
Methods: We examined whether the assessments, i.e. overall score, department scores and skills scores, interns receive by their superiors during their internship year, vary as a function of their gender and the representation of women in the field. We analyzed an archival data set from a large hospital in Israel which included 3326 assessments that were given to all interns who completed their internship year between 2015 and 2019.
Results: Women received lower department scores and skills scores in fields with a low (versus high) representation of women. Men received higher scores in fields with a high (versus low) representation of men, yet there was no difference in their skills scores.
Conclusions: Women are evaluated more negatively in fields with a low representation of women doctors. Similarly, men are evaluated more negatively in fields with a low representation of men, yet this cannot be explained by their skills. This pattern of results might point to a gender bias in assessments. A better understanding of these differences is important as assessments affect interns' career choices and options.
