Student Success Teams and on-Track to Graduation Status in Oregon

This study was designed to investigate the impact of a student success team intervention on the ninth grade on-track to graduation (9G-OTG) rates of students in Oregon. Interrupted time series (ITS) models were used to estimate the baseline change in 9G-OTG rates during the four academic years prior to the implementation of the success team intervention (2013–2014 to 2016–2017) and in the 5 years that followed (excluding 2019–2020). Results demonstrated a slowing of the 9G-OTG growth rate, but a closing of the gap between schools with different take up levels following the onset of the intervention. During the COVID-19 era, a steep decline followed by a sharp rebound in 9G-OTG rates was observed for all implementation levels. Across the intervention years, schools that implemented the success team model experienced a modest gain in 9G-OTG rates while non-implementing schools recorded a slight loss. Implications for education policy and practice are discussed.
