The first requirement is to file an Application for Certificate of Approval to Operate a Real Estate School (ED-100). You'll need to identify each person and, if an entity, every officer, director, member, manager, partner, owner, trust beneficiary holding 10% or more beneficial interest, stockholder owning 10% or more stock, and person exercising control of the school. Supporting documentation is required. A Fingerprint Clearance Card must be provided to the Department by each owner of 10% or more.
Schools should review, understand, and operate under the provisions of A.R.S. § 32-2135 and the Commissioner's Rules, particularly Article 4. You should review and become familiar with those, at the very least. Other statutes within Arizona Revised Statutes, Title 32, Chapter 20, and the Commissioner's Rules (Arizona Administrative Code, Title 4, Chapter 28) also apply.
