What the OCT is

Mask it and it comes back. Neutralize it and it’s gone.

Odor is the complaint that brings a job back. A structure can look fully restored and still smell like the loss — and until the odor is gone, the claim isn’t closed. The OCT teaches your techs to find the source, not chase the symptom.

Students work through the principles of deodorization and the full equipment toolkit — thermal fogging, hydroxyl and ozone generators, HVAC treatment and sealing — matching each method to the odor type so it’s neutralized for good, not covered by a fragrance that fades in a week.

Why take it

Why your team takes the OCT

Certification isn’t a wall decoration. Here’s what the credential actually changes for your techs and your business.

Treat the source, not the symptom

Fragrance covers an odor for a day. Identifying and removing the source is what closes the complaint — and the claim.

Own the deodorization toolkit

Thermal fogging, hydroxyl, ozone, HVAC and sealing — deployed to the odor type, safely and correctly.

Stop the callback

A lingering odor is a return trip on your dime. Done right the first time protects your margin and your reputation.

Add a billable specialty

Odor control is a scoped, billable line item — and the cert that lets your crew take fire, biohazard and pet-odor work with confidence.

The outcome

What you'll walk out with

Two days in, your techs can find an odor source, match the right method and prove it’s gone.

Inside the class

Hands on real losses — not slides.

The Restoration Technical Institute runs inside a live restoration company. Every class is taught on real equipment, in real scenarios, by instructors who still run jobs.

The instructors are the difference.

Working instructors

Every RTI instructor is an active tech, supervisor or estimator — so the answer to “what actually happens on site?” comes from this week’s jobs, not a textbook.

A live flood house

Our training environment gets soaked, mapped, dried and reset every week. Students place real equipment under a real job clock before they ever touch a customer’s floor.

Questions

Before you register.

Still have a question?

Student services can help with prerequisites, group rates, scheduling and licensing requirements in your state.

Contact student services

Do I need a prior certification to take the OCT?

No. OCT has no prerequisites. Many techs take it alongside the FSRT, since fire and smoke losses are where odor control comes up most — ask student services about our FSRT + OCT combo week.

Is the IICRC exam fee included?

The IICRC OCT exam is administered on the final day, but the exam fee isn’t included in tuition — it’s a separate $80 fee paid directly to the IICRC.

Do you cover ozone and hydroxyl equipment hands-on?

Yes. You’ll work with thermal fogging, hydroxyl and ozone generators and learn the safety requirements, run-times and clearance steps for each method.

What should I bring?

Work clothes and closed-toe shoes. All PPE, equipment and course materials are provided.

The Lever360 Platform

Three levers. Pull all three and the whole company moves.

Lever360 is three products built around the same restoration job. Software runs the operation. Learning Lever trains the team. RTI certifies the trade. Use one. Use all three — they compound.

Software is one lever

You're running the company here. The other two make it compound.

Software runs the operation — every job, crew, dollar and conversation lives here. Add Learning Lever and RTI and the same techs ramp faster, bill higher, and stay longer. One lever moves the company. Three move it harder.

Learning Lever is one lever

You're training the team here. The other two make the training stick.

Learning Lever onboards faster and keeps the whole team sharp. Software is where that training shows up in the work. RTI is where it becomes a credential customers trust. Pull one — pull all three and the math compounds.

RTI is one lever

You're certifying the trade here. The other two carry the credential to the field.

RTI certifies the trade — IICRC WRT, ASD, AMRT, FSRT and beyond. Software runs the company those certified techs work for. Learning Lever ramps everyone in between. One lever moves things. Three move the whole crew.
