IAAOInternational Association of Assessing Officers (IAAO) maintains technical standards that reflect the official position of IAAO on various topics that are important to individuals and organizations involved in mass appraisal and related disciplines.

Technical Standards can be purchased individually or as a full set using the Product Order Form . Anyone may freely download individual technical standards for personal reference and use.

IAAO allows reproduction of technical standards for educational purposes, property tax hearings, legislative development, and for public information purposes. The content of IAAO technical standards are subject to change. Current official versions of technical standards are available only from IAAO.

IAAO requests that users of technical standards request permission prior to using them for the stated purposes. Requests for permission to reproduce all or a portion of the technical standards can be sent to Christopher Bennett, bennett@iaao.org.

Technical Standards Committee
The Technical Standards Committee develops and maintains technical standards of professional practice in assessment administration, tax policy, and mass appraisal.

The purpose of this committee is to support the mission and commitments of the IAAO by conceptualizing, organizing, drafting, publishing and maintaining technical standards of professional practice. These standards should address property valuation, property tax administration, and property tax policy and should describe desirable models for the profession.
