Total Score 0-2: The score is LOW risk. No Follow-Up needed. Child has screened negative. Rescreen at 24 months if the child is younger than 2 years old (or after 3 months has elapsed), and refer as needed if developmental surveillance or other tools suggest risk for ASD. Total Score 3-7 : The score is MODERATE risk. Administer the M-CHAT-R Follow-Up items that correspond to the at-risk responses. Only those items which were scored at risk need to be completed. If 2 or more items continue to be at-risk, refer the child immediately for (a) early intervention and (b) diagnostic evaluation. Total Score: 8-20 : The score is HIGH risk. It is not necessary to complete the M-CHAT-R Follow-Up at this time. Bypass Follow-Up, and refer immediately for (a) early intervention and (b) diagnostic evaluation.
