Table 18 on page 171 in the ASQ-3 User’s Guide contains all of the means, standard deviations, and cutoff scores for each area of all 21 intervals. On ASQ-3, the cutoff score is 2 standard deviations below the mean; the data in the 2.0 SD column represent the cutoff for referral zone. The monitoring zone is between 1-2 standard deviations so the monitoring cutoff (bottom end of the zone) is 1 standard deviation; the data in the 1.0 SD column represent the monitoring zone cutoff.
