Ratio Studies Survey
Periodically over the past 20 years, prevalent practices and issues in ratio studies have been explored by comparing U.S. states, Canadian provinces and territories, and a few local jurisdictions in terms of frequency of studies, standards used to evaluate results, and final use of results. The newest surveys were conducted by the IAAO Research and Standards Committee in 2022 and the results were released in May 2023.
Disclaimer: Users of this data should exercise caution when interpreting totals. Some totals in the final report are different from the raw data based on interpretation and selective follow-up.

GIS Technology Survey for Assessment Professionals
Keeping up with the changes in technology in the assessment industry is an important task for all assessment offices and an area IAAO continues to work on to assist members. In 2018 IAAO conducted a survey among members regarding the use of GIS tools and technologies in valuation offices and the full results charted from the 20 question survey are now available as the GIS Technology Survey for Assessment Professionals.The survey received 509 responses from IAAO members and the goal of the survey was to identify both common uses of GIS and emerging applications of newer GIS technologies to expedite daily operations and enhance mass appraisal. There has been a demand to discover what our industry has already embraced and to identify what uses of GIS technologies are quickly coming down the road.
Detailed survey finding charts were created using R, an online open-source software (free at www.r-project.org) to illustrate what can be accomplished using free statistical and data analysis tools. If you have questions regarding the survey or responses please contact IAAO.
PTPA Survey (formerly the PTAPP)
In 2023 IAAO is conducting the Property Tax Policy and Administration (PTPA) survey as a follow up to the 2017 Property Tax Assessment Policies and Practices Survey (PTAPP)
In response to a need for current information about property tax systems, IAAO has published surveys of the features of property tax systems in Canada and the United States. This compilation is the latest in the series. Although the main audience is property tax administrators and policy makers in the two countries, readers from other countries may find it helpful as well.
2017 PTAPP Findings
The Update of the Property Tax Assessment Policies and Practices Survey (PTAPP), published in the IAAO Journal of Property Tax Assessment & Administration (Vol. 16, No. 1, 2019) was compiled by the 2018 PTAPP Task Force lead by Alan Dornfest, AAS. Task force members included: Jennifer Rearich, MAS, Richard Almy, and Doug Brydon along with input and assistance from IAAO staff members, Heather Steel and Margie Cusack.
For the first time, PTAPP results may also be viewed on an inactive map allowing for greater visualization of locational response, this effort was made possible by the additional efforts of Jennifer Rearich, MAS wishing to illustrate the enhancement and benefits of geospatial data display.
