When rescreening, the questionnaire used depends upon the age of child and the questionnaire's administration window. You should use the age-appropriate questionnaire when rescreening. You may decide to rescreen with the same questionnaire if the child remains in the age administration window and, if the child passes that interval, rescreen in 4-6 months with the next age interval. The most important thing is to follow up consistently if children score in the referral area or if there are concerns.
