# 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](/content/wp-content/uploads/2017/05/ASQ-3-Technical-Appendix_web.pdf)) shows the mean and standard deviations for each ASQ-3 interval. The bell curve is not typical, however, so calculating percentiles is not straightforward.
