A random sample of 1,000 Nationally Certified School Psychologists were mailed a 17-item survey about treatment integrity. A total of 132 responded and answered questions about the importance of treatment integrity data for tiered interventions and the frequency and methods used to measure treatment integrity in one-to-one and problem-solving team consultation. Ninety-eight percent agreed that treatment integrity data were critical for tiered interventions. However, only 7% in one-to-one consultation and 0% in team consultation reported it was "always" collected. Respondents identified barriers of time, workload, system factors, and staff knowledge as explanations for why there was a gap between belief and practice. The participant responses were compared to those from a 2008 survey and found to be almost unchanged. Issues associated with decision-making when treatment integrity data are lacking and recommendations for improving the assessment and reporting of treatment integrity are discussed.
