Who Can Take the Society of Industrial and Office Realtors (SIOR)? (Eligibility Requirements)

═══════════════════════════════════════════════════════════════════════════════

The SIOR designation has some of the strictest eligibility requirements in the real estate industry. Candidates do not simply “take a test”; they must prove their professional worth through production data.

Eligibility Checklist

  • Academic Requirements: A Bachelor’s degree or higher from an accredited university is standard. Candidates without a degree may occasionally qualify through significant additional years of experience (subject to board review).
  • Experience Requirements: Candidates must have a minimum of five (5) years of full-time active experience in commercial real estate brokerage immediately preceding the application.
  • Gross Fee Income (GFI): This is the “hardest” filter. Candidates must meet a minimum GFI requirement (the “Production Requirement”) within their local market for three out of the last five years. These amounts vary by market (Market A, B, or C). For example:
    • Market A (Large Hubs): Often requires $500,000+ GFI annually.
    • Market B (Mid-Sized): Often requires $300,000 – $400,000 GFI annually.
    • Market C (Smaller Markets): Often requires $200,000 – $250,000 GFI annually.
  • Documentation Checklist:
    • Certified GFI production reports signed by the managing broker.
    • Detailed transaction history for the qualifying years.
    • Two endorsements from active SIOR designees in the candidate’s local chapter.
    • Proof of active membership in the National Association of Realtors (NAR) or a recognized international equivalent.
    • Copy of current Real Estate License.
  • Language Proficiency: While there is no formal IELTS requirement, all coursework and exams are conducted in English (with some regional localized support in Europe and Mexico).
