This Data Note describes findings from a nationally representative sample of secondary school principals about their well-being and job-related stressors one year into the coronavirus disease 2019 (COVID-19) pandemic. Understanding principals' views on these topics at a national level can help education leaders and policymakers identify ways to support principal wellness, reduce job-related stress, and improve job satisfaction, performance, and retention. The authors use nationally representative survey data of "secondary principals," defined as principals who serve in schools that include any grade from 6th grade to 12th grade, from the 2021 Learn Together Surveys (LTS) to examine the state of principal well-being. The 2021 LTS was administered in March and April 2021 to 1,686 secondary principals, one year after the start of the COVID-19 pandemic. This Data Note highlights principals' responses to the open-ended survey, discusses key findings, and concludes with implications and policy recommendations.
