The public health crisis created by the spread of COVID-19 has disrupted day-to-day rhythms across the United States, including an extended closure of school buildings. Myriad news sources and emerging research are reporting on the deep and disparate effects that are reverberating from these closures. But how do young people themselves perceive the impact so far on their learning and their lives? To answer this question, the Center for Promise at America's Promise Alliance collected data from a nationally representative survey of 3,300 young people, aged 13-19, that was conducted as part of the "How Learning Happens" initiative. Respondents were asked a series of questions about their social, emotional, and academic experiences across both school and out-of-school-time learning settings, including a set of questions related to their specific experiences since being out of school as a result of COVID-19. At the time of the survey administration, a two-week period during late April and early May 2020, two-thirds of respondents had been out of school for more than four weeks. This research brief offers a snapshot of young people's self-reported: (1) Participation in online learning; (2) Connections to peers, adults at school, and their school community; (3) Top-of-mind concerns; and (4) Indicators of health and wellbeing. Findings suggest that students are experiencing a collective trauma, and that they and their families would benefit from immediate and ongoing support for basic needs, physical and mental health, and learning opportunities. Without that support, this moment in time is likely to have lasting negative effects for this cohort of high school students.
