Testing Coverage

Iowa requires all children to be tested at least once before the age of six. The recommendation is to start testing prior to age three. The under 3 birth cohort testing data can be helpful for healthcare providers and local public health agencies for program assessment and improvement; however, the Birth Cohort Children Under 6 is a better indicator of compliance with the testing requirement.

The number of children born from Vital Statistics data does not include children who have moved in or out of the area since birth. Therefore, as a denominator, vital statistics data may under or overestimate the number of 3 year old children in the area. It is possible that there were more children tested in a County during the time period than were born in that County causing the Percent of Birth Cohort Tested to be greater than 100%.
