Is there a cutoff point for the monitoring zone on ASQ-3, as there is for the referral zone?
The gray area or monitoring zone on ASQ-3 represents the range of scores between 1 and 2 standard deviations below the mean for each area. The top edge of the monitoring zone is 1 standard deviation below the mean and the bottom edge (also the cutoff score) is 2 deviations below the mean. The chart on page 171 of the…
Can the ASQ-3 scores be translated into percentile rank and, if so, what is that percentile?
The ASQ-3 cutoff scores are set at 2 standard deviations below the mean. The monitoring zone is between 1 and 2 standard deviations below the mean. Table 18 in the technical appendix (page 171 in the User’s Guide or available here ) shows the mean and standard deviations for each ASQ-3 interval. The bell curve is no…
The age ranges for the 9 and 10 month old questionnaires overlap, but the cutoff scores on the two intervals are different. If we used the 10 month questionnaire for a child 9 1/2 months, his score falls into the monitoring zone, but if we use the 9 month questionnaire his scores falls in the normal range. Which questionnaire interval do you recommend using for a child between 9 months, 0 days and 9 months, 30 days?
The cutoff scores do differ between the 9 month and 10 month questionnaire intervals. The developers added the 9 month questionnaire with the third edition of ASQ in 2009, primarily to meet the needs of pediatricians following the American Academy of Pediatrics’ recommendations to screen at 9, 18, and 30 months.

When do you refer a child when using ASQ-3?
There are several instances where a professional may decide to refer a child after completion of ASQ-3. For the 5 developmental areas covered by ASQ-3, the tool uses cutoff scores to determine whether a child should be referred. The cutoff scores were developed through a standardization process and are set at 2 stand…
