IID-19 Data Details

Expand All

IID-19 Increase the number of States collecting kindergarten vaccination coverage data according to CDC minimum standards

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
Annual School Assessment Reports; Centers for Disease Control and Prevention, National Center for Immunization and Respiratory Diseases (CDC/NCIRD)
Changed Since the Healthy People 2020 Launch: 
Yes
Measure: 
number
Baseline (Year): 
11 (2009–10)
Target: 
51
Target-Setting Method: 
Maintain consistency with national programs, regulations, policies, and laws.
Target-Setting Method Justification: 
This target will monitor compliance with school requirements and ensure optimal vaccine preventable disease risk outbreak management. An initiative has been launched to standardize kindergarten coverage assessment methods, which involves development of best practices, validation of assessment methods, provision of technical assistance, and close monitoring of State activities.
Numerator: 

Number of states (including the District of Columbia) who collect kindergarten vaccination coverage data according to CDC minimum standards

Comparable Healthy People 2010 Objective: 
Not applicable
Data Collection Frequency: 
Annual
Methodology Notes: 

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

    States are asked to use comparable methods to allow comparison and to ensure that the information collected is accurate. States meeting the criteria for this objective must employ a methodology that meets the following standards: (1) all age-appropriate ACIP recommendations must be followed, including 2 doses of varicella, (2) appropriate sampling methodology must be used, (3) data collected must be validated, (4) data collection should only be done by trained personnel, (5) data on vaccination history should come from a provider, and (6) data should be collected collected by the 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). Measurement of this objective may be affected by improvements in the school assessment report questionnaire used to collect this data from states, which have led to a clearer understanding of methodology questions among the states and a more accurate and more complete understanding at CDC of methods states use to collect school vaccination assessment data.
Trend Issues: 
The IID-19 component that requires data to be collected by December 31 was not considered in 2009-10 nor in 2011-12, but was considered for 2013-14.

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.
