Results: North Suburbs Assessment Quality
The CCAO is committed to measuring the quality of its valuations. After the reassessment of each
township, we publish reports that include self-studies using the IAAO’s standards for Accuracy,
Uniformity, and Equity for our estimates of values of single-family homes.
In the north suburbs, 12 of 13 townships met all three metrics for high-quality assessment.
