Methodology Notes

This measure is designed to encourage states to follow standard procedures and methodology that will result in quality data.

The states are asked to use comparable methods to allow comparison and to ensure that the information collected is accurate. The methodology must include these standards: (1) Meeting all age-appropriate ACIP recommendations , including 2 doses of varicella, (2) Appropriate sampling methodology, (3) Validation of data collected, (4) Data collection by trained personnel, (5) Data on vaccination history from a provider, and (6) Data collected by appropriate date (December 31 of each year).

Caveats and Limitations
Sampling methodology varies by state for kindergarten vaccination status, which is a major limitation (e.g., some states selected a random sample of kindergarten children and others conducted a census of all kindergarten children).

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch

In 2013, the original baseline and baseline year were revised from 13 (2009) to 11 (2009-10) because reliable data were not available before the 2009-10 school year. The target was not revised. In 2013, "Number of states (including the District of Columbia)" was removed from the denominator description because the unit of measurement is number of States, not percent.
