The purpose of this exploratory study was to examine the coming out experiences of gifted LGBTQ (lesbian, gay, bisexual, transgender, and questioning or queer) alumni from a residential gifted high school. First, we found that gifted LGBTQ alumni (N = 106) realized their sexual orientation/gender identity around 16.6 years old, which is similar to the general population. The year of high school graduation did not correlate with the age of initial realizations, or when they shared. On average, when the participants did share, they waited 2.1 years to share with friends and 3.4 years to share with family. Furthermore, they felt more comfortable sharing within the residential gifted high school than in their home schools. In general, LGBTQ alumni felt more autonomous, competent, and connected to the residential school. Finally, participants reported many barriers to coming out, including both internal struggles (e.g., uncertain themselves) and social fears (e.g., fear of alienation or harassment). These findings can provide guidance for school personnel as they develop effective, support systems.
