Prove Assessment Fairness with IAAO-Compliant Audits
Automated ratio studies, equity metrics, and compliance reports for Indiana's 92 county assessor offices. COD, PRD, PRB analysis updated with every new sale.
The Problem
- DLGF compliance requires ratio studies that most counties outsource expensively
- Sales chasing detection requires comparing treatment of sold vs. unsold properties
- Demographic disparity analysis is mandated but labor-intensive
- Year-over-year trending and peer comparison require maintaining historical data
How Equity Audits Helps
IAAO Ratio Studies
Coefficient of Dispersion (COD), Price-Related Differential (PRD), and Price-Related Bias (PRB) calculated at county, township, neighborhood, and property class levels.
Sales Chasing Detection
Statistical tests to identify differential treatment of recently-sold properties vs. unsold properties.
Compliance Reports
Print-ready PDF reports formatted for county council presentations and DLGF submission. Automatic threshold alerts.
Demographic Disparity Analysis
Assessment equity overlaid with Census tract demographics to identify potential disparate impact by race, income, or neighborhood.
Peer County Comparison
How does your county's COD compare to similar-sized counties? Benchmarking dashboards with statewide context.
Frequently Asked Questions
We implement the IAAO Standard on Ratio Studies (2013, updated 2023). This includes COD, PRD, PRB, and the recommended sample size thresholds for each geographic breakdown.
Reports recalculate automatically whenever new sales or assessment data arrives from state or county sources. Most counties see updates weekly.
