About This Show
AI-drafted summaryThe IAAO Annual Conference is the flagship gathering of the International Association of Assessing Officers, the professional body serving property assessment and valuation officials. The conference bills itself as the premier platform for sharing successes, discovering best practices, and learning from expert colleagues about the latest research in property appraisal and valuation. The 2026 edition takes place October 13–16 in Calgary, Alberta, Canada, at the Calgary TELUS Convention Centre.
The event draws assessors, appraisers, tax administrators, mass-appraisal specialists, GIS and valuation-technology professionals, and vendors serving the assessment community from across North America and around the world. Each year, educational sessions, networking opportunities, events, and a varied exposition give assessment professionals the tools they need to succeed, and attendees interact with peers from across the country and around the globe.
Attendees can earn continuing-education (CE) credits, preview the latest solutions in the exhibit hall, and take part in signature networking events. With a large and consistent turnout — nearly 1,700 people attended in 2025 — the conference is a valuable stop for anyone working in property tax, assessment administration, or mass appraisal who wants current research, practical education, and industry connections in one place.
Show Highlights
The 2026 conference adopts a new format spread across four days:
- Tuesday, Oct. 13 – Welcome Reception, plus an optional Local Host Committee event, "Curling 101: A Canadian Experience."
- Wednesday, Oct. 14 – Keynote address, Exhibit Hall, and educational sessions.
- Thursday, Oct. 15 – Plenary session, Exhibit Hall, and educational sessions.
- Friday, Oct. 16 – Educational sessions and the Awards Gala.
Signature features include the Exhibit Hall with exhibitor showcase sessions, an extensive schedule of educational sessions eligible for CE credit, and networking events. Optional add-on experiences hosted by the Local Host Committee include Curling 101 (\$40 USD plus tax, round-trip bus transport to the Calgary Curling Club) and a self-guided day trip to Banff on Saturday, Oct. 17 (\$50 USD plus tax).
Attendance
According to IAAO, nearly 1,700 people attended the 2025 Annual Conference in Orlando, Florida. The audience is composed of property assessment and valuation professionals — including assessors, appraisers, mass-appraisal and GIS specialists, and tax administrators — from across North America and internationally. No official demographic breakdown for the 2026 Calgary event has been published.
