Participants were 7th and 8th grade students in a suburban Maryland public school. This study was quasi-experimental, utilizing a pre-test, post-test design. The null hypothesis that the setting of the SWPBIS was not related to overall attendance was rejected at the customary alpha=.05. This indicated that there was a statistically significant decline in mean overall attendance between SY2020 (in-school) and SY2021 (virtual). The independent variable of positive communications, a major SWPBIS strategy, had a positive impact on student attendance for SY2021. Research should continue, as the study was impacted adversely by threats to validity due to COVID-19.34 pagesen-USThis work may be protected under Title 17 of the U.S. Copyright Law.
