The present study sought to assess the ability of teachers to identify emerging mental health disorders through a novel vignette measure. Canadian certified primary grade teachers (N = 101) completed a survey that included a novel vignette measure. Participants rated the severity of fictitious student behaviors depicted in several vignettes and their accuracy was calculated based on how closely their ratings matched the severity of symptoms depicted. Accuracy estimates derived through this measure differed considerably from previous vignette measure paradigms, producing much lower estimates of identification accuracy. A binomial logistics regression indicated that neither the gender nor pathology depicted in the vignettes significantly influenced rating accuracy. This novel vignette measure may represent a quick and effective means of assessing the accuracy of teachers in identifying emerging mental health disorders in their students.
