DESSA results are reported using T-scores and percentile ranks. Tools are also available for pre-test/post-test comparisons and rater comparisons. Online administration produces individual student, classroom, site, and program-level reports.
|Evidence of Technical Quality|
|Populations for which technical quality evidence has been collected||
A nationally representative sample of 2,500 children from across the United States (LeBuffe et al., 2009). Ratings were provided by teachers, out-of-school time staff and parents/guardians, 227 raters from across the United States (Nickerson & Fishman, 2009).
Internal consistency coefficients were estimated for the Social-Emotional composite as well as the eight subscales; they were estimated separately for parent and teacher raters. Coefficient alpha ranged from 0.82 to 0.99. Test-retest reliabilities ranged from 0.79 to 0.90 (parents), and 0.86 to 0.94 (teachers/staff). Intra-rater reliabilities had correlation coefficients of 0.73 for parents, and 0.74 for teachers/staff (LeBuffe et al., 2009).
