Background: The adoption of remote classes for students has been in vogue since the onset of the pandemic. Schools reopened in a phased manner after the second wave of coronavirus disease 2019 (COVID-19) in India. Reverting to the regular face-to-face teaching for students became a challenge to the teachers and students, especially at times when there was an impending third wave on the way. The study aimed to assess the presence of symptoms of depression, anxiety, and stress in teachers who attended reopened schools in the scenario of face-to-face classes. In addition, we studied the association of psychological symptoms with teachers' age groups, gender, school boards, and school institution type. Methods: A cross-sectional study was conducted between October to December 2021 after schools had reopened. Data was collected using Google Form questionnaires in 124 schoolteachers. The Depression, Anxiety, and Stress Scale - 21 Items (DASS-21) questionnaire assessed the psychological symptoms. Results: Of 124 schoolteachers, 108(87.1%) were female, 112 (90.3%) were from private institutions, and 70(56.5%) were from Central Board of Secondary Education (CBSE) school boards. The prevalence of depression, anxiety, and stress in teachers was 30.6%, 45.2%, and 20.2%, respectively. Nearly 80% of the female teachers expressed depression, anxiety, and stress symptoms. Amongst all the age groups, symptoms were higher in 40-49 group. We found anxiety to be statistically significant when compared with gender (p-0.042). We found no statistically significant differences concerning age groups, school boards, or school institutions with any psychological symptoms. Conclusions: The prevalence of psychological symptoms was high among schoolteachers after schools reopened for regular face-to-face teaching. Gender was associated with anxiety in teachers. We agree that identifying teachers' symptoms and providing adequate psychological counseling/support would improve their mental health status and thereby the quality of teaching to students.
