How do you become a home inspection instructor or mentor?

In Texas, Oregon, and Washington, an instructor works through an approved school or course provider, which answers to the state for its instructors. A state that requires supervised field training also sets who can supervise it, such as an inspector licensed four years in Washington or five in Alabama.

Classroom instructors in Texas

Texas writes instructor qualifications into its rules. TREC's instructor qualifications page and its rule, 22 TAC 535.63, set two levels for inspector courses.

Texas instructor qualifications for inspector courses
Course	What the instructor needs
Qualifying (pre-license) courses	A college degree in the subject and three years of teaching or training; or five years as an active license holder and three years of teaching or training; or an equivalent background the provider accepts
Texas Practicum, ride-along course, Legal and Ethics and SOP Review	Five years as an active Texas professional inspector, plus either 200 inspections as one or three years of teaching or sponsoring apprentice or real estate inspectors
Elective continuing education	Competent in the subject and able to teach effectively

Oregon and Washington approve the course

In Oregon, the education provider applies to the Construction Contractors Board. Under OAR 812-008-0074, it certifies that its instructors have experience in the subject, licenses or degrees in it, a background in training or adult education, and knowledge of the home inspection industry.

Washington approves courses under WAC 308-408B. The rule sets no instructor credentials. It asks that the course run under an instructor who is, at a minimum, available to answer specific questions. A pre-license course needs at least 120 hours, and a CE course at least two. Russ Motyko has taught the classroom portion of Washington's pre-licensing course and has taught more than 100 new inspectors.

Approval stops at the state line. A course built for both states goes through both processes.

Who can supervise field training

Several states require supervised inspections before a license, and each sets who can do the supervising. These are the rules on the state pages of this site, checked in October 2026.

Field training rules and supervisor requirements by state
State	What the trainee does	Who can supervise
Washington	40 hours of field training, with at least 5 complete inspections and written reports the supervisor reviews	An inspector with 4 years of licensure
Arizona	30 parallel inspections, with no more than 3 other applicants present	Certified for at least 3 years, with at least 250 fee-paid Arizona inspections
Alabama	35 or 100 inspections, depending on hours of education, plus 25 draft reports, 10 reviewed and corrected	Licensed in their own state for the past 5 years, or 5 years in a listed association where there is no license
New Jersey	250 fee-paid inspections, on the experience route in place of the course	A New Jersey licensee with at least 500 inspections and 3 years
New York	100 inspections, on the route in place of the course	A New York licensed inspector, engineer, or architect
Texas	25 inspections under direct supervision, on the apprentice path	A professional inspector, who can sponsor apprentices
Oregon	Optional ride-alongs, 1 eligibility point each	An Oregon certified home inspector

Oregon pays the mentor back in hours. Its CE rule gives one CEU per clock hour of ride-along training. Washington's CE rule gives instructors no credit for teaching.

Before you take on a trainee

Russ's advice to a first-time mentor comes down to paperwork and plain agreements:

Confirm you meet your state's supervisor rule before the first job.
Tell each client a trainee will be there, and get their consent.
Agree in writing on the fee, the schedule, and what the trainee does on site.
Log every inspection: date, address, hours, and your license number.
Sign the trainee's forms promptly, since the license application waits on them.

The forms vary. Alabama wants a signed verification from each supervisor on the trainee's log, and Arizona wants one from each parallel inspector. Delaware's law bars a supervisor from requiring a trainee to pay a fee or sign a non-compete. In the other states here, no rule sets what a mentor charges, so the fee is whatever the two of you agree to. For the trainee's side, see how to find a home inspector ride-along.

Why teach at all

The pay is rarely the point. A mentor gets to know the new inspectors in the market, and a teacher has to explain why a defect matters, which sharpens the teacher's own reports. If you build a course of your own, write it to the approval rules from the start: the state's topic list, its minimum length, and its definition of a clock hour.

For what else an experienced inspector can do, see what else a home inspector can do. For the hours your own renewal needs, see how much continuing education home inspectors need.

Questions people ask

Do Texas inspection instructors have to be inspectors?

For the Texas Practicum, the ride-along course, and the Legal and Ethics and SOP Review, yes: five years as a Texas professional inspector, plus 200 inspections or three years of teaching or sponsoring. Other qualifying courses also accept a college degree in the subject with three years of teaching or training.

Do Oregon inspectors earn CE credit for mentoring?

Yes. Oregon gives one continuing education unit for each clock hour of ride-along training given to an applicant.

Do Washington instructors earn CE credit for teaching?

No. Washington's rule says instructors get no clock hour credit for teaching or for developing a course.

How long do you need to be licensed to supervise field training in Washington?

Four years. The rule changed on August 8, 2026 to require a supervisor with four years of licensure.
