The ASQ is a flexible system and it allows programs to choose the frequency of screening based on what works best with your program’s goals and capabilities. In general, the developers recommend rescreening a child who scored in the monitoring zone (gray area) in 2-3 months. This allows the child to practice skills, especially those where lack of opportunity may have had an impact. Depending on the child's age, you may need to rescreen with the same interval, or the next interval.
