|Evidence of Technical Quality|
|Populations for which technical quality evidence has been collected||
Evidence comes from a sample of teachers, parents, and students from across the United States.
Internal consistency was calculated for all three scale scores for all forms. Median Cronbach's alpha = 0.96 (teacher), 0.96 (parent), and 0.94 (student).
Test-retest reliability within a three-month period was calculated for the subscales for all forms. Median correlation = 0.83 (teacher), 0.86 (parent), and 0.79 (student).
Inter-rater reliability for two raters was calculated for all subscales for parent and teacher forms. For teacher forms, the median reliability coefficient was 0.62; for parent forms, median reliability was 0.55.
