Step 3: Summarizing Results: Percentiles and T-scores
Step Three of the DECA Program involves summarizing DECA results for the individual child and for the classroom as a whole.
  1. Two types of standard scores are provided for each child: Percentiles and T-scores.
  1. Children's results in protective factors that fall one or more standard deviations above the mean are classified as "strengths" (T score = 60 or more). Children's results in protective factors that fall one or more standard deviations below the mean are classified as "concerns" (T score = 40 or less). Results within one standard deviation on either side of the mean are classified as "typical" (T score = 41-59).
  1. Children's results in behavioral concerns that fall one or more standard deviations above the mean are classified as "concerns" (T score = 60 or more). All other results are considered "typical" for behavioral concerns (T score = 59 or less).
