In 2020, the Coronavirus 2019 (COVID-19), a highly infectious and deadly respiratory disease, quickly spread into a worldwide pandemic. This study investigated posttraumatic growth (PTG) among K-12 educators in the United States after teaching during the COVID-19 pandemic. The research problem is that educators experienced trauma that is unique to them by teaching during the pandemic. Trauma can have long-lasting, adverse effects. Nevertheless, the PGT advances that people can develop positive psychological growth because of trauma. The purpose of this cross-sectional, correlational quantitative study was to investigate the relationship between COVID-related trauma and PTG in the personal strength domain of the K-12 educators who experienced COVID-related traumas. Ninety-two participants completed an online survey comprising a demographic questionnaire and Posttraumatic Growth Index-Extended (PTGI-X) to rate their PTG. A sample of 73 was included for data analysis. Correlation tests, regression analysis, and t-tests addressed the two research questions. First, to establish if there was a relationship between COVID-related trauma and the development of PTG; second, to establish the correlation between the grade levels taught by the teachers during the pandemic and the development of PTG. The results indicated that 86% of the participants developed PTG irrespective of the grade levels taught during the pandemic. The researcher concluded that there was a relationship between COVID-19 trauma and the development of PTG in this sample and that this relationship developed irrespective of the grade levels taught, as evidenced by a non-significant negative correlation result of r (68) = -0.02, p = 0.884. The findings are anticipated to add to the body of knowledge regarding educators' PTG post-COVID-19 pandemic. These findings can be utilized by educators, school districts, psychologists, and others in developing programs to address educators' COVID-related trauma.
