This article explores the effectiveness of a mandatory training workshop for faculty. Our center for teaching and learning (CTL) was charged with designing and implementing a diversity training workshop for all full-time faculty. The workshop included an introduction to diversity and inclusion, analysis of microaggressions, discussion of inclusive teaching strategies, and practice responding to difficult situations using realistic classroom scenarios. Data were collected on participants' familiarity and comfort level with diversity and inclusion concepts and situations via identical pre- and post-assessment. A year later, a follow-up survey was administered, which included the original assessment. Assessment and survey responses indicated positive short-term and long-term gains in awareness and use of inclusive teaching strategies.
