As Response to Intervention (RtI) approaches become more common in educational systems throughout the country, it is increasingly important to identify how practitioners perceive these changes and how they obtain the skills necessary to face emergent roles and responsibilities. In this exploratory study, a national sample of 557 school psychologists were surveyed regarding their training, involvement, and perceptions of RtI. The results indicate that practitioners engage in multiple training experiences via a variety of modalities. Nearly half of respondents reported employment at sites implementing RtI. Practitioners at RtI-implementing sites reported a greater proportion of their time spent in academic intervention and conducted fewer psychoeducational assessments relative to their peers at non-RtI-implementing sites. Although many reported that RtI had positive effects on academic performance, a sizeable proportion of practitioners observed no effect on school culture and climate. Implications for school psychology training and practice are discussed. (Contains 4 tables.)
