Training programs in science, technology, engineering, and math (STEM) share a common goal of enhancing education and support for their students, emphasizing the importance of measuring student access, engagement, and retention across disciplines and training levels to understand their impact. Demographics should be representative of the complexity and intersectionality of student identities, with Executive Orders calling for expansion of demographic data collection practices to incorporate broader categories of race, ethnicity, religion, income, geography, gender identity, sexual orientation, and disability. In August 2023, OHSU received a new five-year Science Education Partnership Award from the National Institutes of Health’s Office of Data Science Strategy to expand data science training for middle and high school students. The collaborative project aims to 1) identify considerations for inclusive demographic data collection and responsible reporting; 2) establish a training collaborative that aligns qualitative research with data science outputs to enhance authentic representation of a diverse biomedical workforce; and 3) characterize how demographic data are used to make decisions and inform practice.
