Annual School Assessment Reports

These state-based surveys are the primary source of information on vaccination coverage of children in childcare, kindergarten, and middle school.

States and U.S. territories and affiliated islands enact laws or regulations that require children to receive certain vaccines before they enter childcare facilities and school. They report the results of periodic assessments of vaccination coverage in childcare facilities and the results of annual reviews of vaccination records in schools, conducted at the beginning of each school year. In addition, states conduct studies to validate reports from schools. Results from school studies are used to ensure high vaccination coverage among school students. A summary of the results of coverage among children in child care facilities and schools is reported to the CDC's National Center for Immunization and Respiratory Diseases. Consequently, school entry surveys should reflect an accurate picture of the immunization levels of children entering school.  Nationally the levels reported are high (usually greater than 95%).

Why School Assessments are Important

School-based immunization surveys are frequently used to assess vaccination coverage for communities. Immunizations surveys of medical charts in providers’ offices cannot assess vaccination levels of groups of interacting children because these children receive care from different providers. The school-based immunization survey provides a unique and simple method to study vaccination rates of interacting populations.

School-based immunization surveys gather patient-level details about vaccination histories during the preschool years of life, the time when children are most vulnerable to vaccine-preventable diseases. Because school-based data include children who have no identified provider or who change providers, these surveys are useful for identifying groups of children who may lack connections to the primary care system.
