Each year, according to Indiana Code 20-8.1-7-11, all schools in Indiana are required to self-report immunization coverage levels of their kindergarten, first grade, sixth grade, and newly enrolled students to the immunization program at the Indiana State Department of Health (ISDH). In order to verify the accuracy of the reports sent to ISDH, the immunization program annually conducts a validation survey on a random sample of schools. The results of the school validation survey for the 2002 - 2003 school year are represented in this report.
A random sample of schools was selected from the 2,164 schools listed in the 2002 - 2003 school immunization assessment database. This sampling was conducted according to procedures developed by the Assessment Branch of the National Immunization Program at CDC. Factors involved in this sampling include: total number of students, approximate immunization coverage levels, and acceptable level of error in sampling. Using this methodology, a total of 102 schools were selected for validation. Of these, 34 were selected for a validation of their kindergarten immunization report and 33 for a validation of their sixth grade immunization report (i.e. of the schools with kindergarten and sixth grade students combined, 32 sites were selected to receive validations for both grades). Validations for the first grade were completed at 35 schools using the standardized random selection.
ISDH immunization field representatives reviewed records for the up-to-date or exemption status of students in the selected grade levels at each of the 102 schools chosen to receive a validation. Complete immunization levels for each grade level were then calculated and compared with the school’s reported immunization coverage levels for the 2002 - 2003 school assessment. In order to determine overall coverage levels for each school, grade-level validation findings were combined at those schools where more than one grade was validated.
The Indiana State Department of Health validated 102 schools from the 2002 - 2003 annual school immunization assessment.

---|---|---|---|
1995-1996 | 97% | - | 98% |
1996-1997 | 97% | - | 98% |
1997-1998 | 97% | - | 98% |
1998-1999 | 97% | - | 98% |
1999-2000* | 81% | 66% | 97% |
2000-2001 | 90% | 95% | 95% |
2001-2002 | 92% | 84% | 97% |
2002-2003** | 85% | 96% | 75% |
*For the 1999-2000 school year, implemented new school requirements, which affected kindergarten and first grade students. First grade immunization rates began to be collected with the new requirements.
**Vaccine shortages were experienced during the 2002-2003 school year.
The results of the 2002 - 2003 school immunization validation survey indicate one-fourth of the schools showed no change between the school assessment report and school validation survey.
