This study examines predictors of abandonment of evidence-based practices through descriptive analyses of extant state-level training data, fidelity of implementation data, and nationally reported school demographic data across 915 schools in three states implementing school-wide positive behavioral interventions and supports (SWPBIS). Schools included in this study were tracked for a 5-year period after initial training, yet some elected to abandon SWPBIS at various times during implementation. Results showed that a small proportion of schools in the sample abandoned SWPBIS (7%). Logistic regression analysis identified school locale as the only statistically significant predictor of SWPBIS abandonment with schools located in cities being more likely to abandon. Results are discussed in terms of addressing types of schools at greater risk for abandonment and the importance of state-level training and coaching support.
