TL;DR
Arkansas has no state-issued HERS rater license. Certification comes from RESNET, the national standards body. You train through an accredited Rating Provider, pass field and written evaluations, and pay RESNET membership fees. The full path from enrollment to first rating usually takes two to six months, depending on your schedule and testing availability.
Do you need a state license to be a HERS rater in Arkansas?
No. Arkansas does not issue a state HERS rater license. There is no Arkansas state board, no Arkansas-specific exam, and no state application form to file. The credential that lets you produce legally recognized HERS ratings in Arkansas is RESNET certification, administered by the Residential Energy Services Network under its Mortgage Industry National Home Energy Rating Standards.
That matters because a lot of people search for a state license, assume it must exist, and burn weeks hunting for paperwork that was never created. Arkansas defers entirely to RESNET's national framework rather than layering on a parallel state credential. [1]
That said, if you plan to rate homes under certain utility programs, a specific builder contract, or an EPA ENERGY STAR path, those programs may require you to be affiliated with a specific RESNET-accredited Rating Provider or to carry additional E&O insurance. Check with the program administrator, not with any state agency, because those requirements come from the program, not from Arkansas law.

What is RESNET certification and why does it replace a state license?
RESNET is a nonprofit standards body that wrote the HERS Index methodology and accredits the training providers, software tools, and raters who use it. Fannie Mae, Freddie Mac, the EPA ENERGY STAR program, and the DOE Zero Energy Ready Home program all recognize RESNET-certified raters as the qualified professionals who can generate a HERS Index score. [2]
Because the federal mortgage and energy programs accept RESNET certification directly, states do not need to create a parallel credential. Arkansas followed that pattern. A RESNET-certified rater in Fayetteville can rate a home for FHA financing or ENERGY STAR the same way a rater in California does, using the same national standards.
The specific RESNET standard governing rater certification is the Mortgage Industry National Home Energy Rating Standards (MINHERS), currently in its 2019 edition with subsequent addenda. [3] That document defines who can call themselves a HERS rater, what training they must complete, what field work they must demonstrate, and how their Rating Provider must quality-assure them.
This is not a light-touch credential. MINHERS requires verified field experience, a passing score on RESNET's national exam, and ongoing quality assurance through your Rating Provider after you certify.
How much does becoming a HERS rater cost in Arkansas?
Costs fall into four buckets: training, the RESNET exam, RESNET membership, and equipment. None of these are set by Arkansas. All are set by RESNET and the training provider you pick.
| Cost item | Typical range | Who sets it |
|---|---|---|
| Training course (classroom + field) | $500 to $2,000 | Your Rating Provider |
| RESNET national exam | ~$100 to $200 (confirm with provider) | RESNET / Rating Provider |
| RESNET rater membership (annual) | $179 per year | RESNET [4] |
| Blower door kit (required equipment) | $800 to $4,000+ | Equipment supplier |
| Duct leakage tester | $500 to $2,500+ | Equipment supplier |
The RESNET annual membership fee is publicly listed at $179 for a certified rater. [4] Training costs vary a lot. Some Rating Providers fold exam fees into the course cost; others do not. Confirm all line items in writing before you enroll.
Equipment is the biggest variable. A Minneapolis Blower Door Model 4 runs around $3,200 to $3,800 new from The Energy Conservatory. Used units come up on equipment resale forums and contractor liquidation sales, sometimes under $1,500 if you are patient. A duct blaster or Duct Blaster Series B from the same manufacturer runs roughly $1,600 to $2,200 new. [5] You can also rent equipment when you are starting out, which lowers your upfront cost but raises your per-rating overhead.
HERSPath's entry kit bundles RESNET membership with a blower door kit for $179 one-time, worth a look if you are still in early planning mode. Whatever path you take, do not skimp on calibration. RESNET requires diagnostic equipment to meet specific calibration standards, and gear that cannot pass that check cannot be used for a certified rating. [3]
Most new raters in Arkansas spend somewhere between $2,000 and $7,000 in the first year, depending on equipment choices and whether you rent or buy.
How long does it take to become a HERS rater in Arkansas?
Two to six months is realistic for most people. The variation is almost entirely about your schedule and how fast you can knock out the field observation requirements, not about any Arkansas processing time.
Here is the rough sequence:
1. Find an accredited Rating Provider and enroll. RESNET keeps a searchable directory of accredited Rating Providers on its website. [6] Some providers serve Arkansas residents remotely; others have in-person Arkansas locations. 2. Complete the training curriculum. Most provider courses run three to five days of classroom instruction, sometimes spread over a weekend or two. Some offer online modules for the didactic portion with in-person field days. 3. Complete supervised field observations. MINHERS requires candidates to complete a set number of supervised ratings with a certified rater before sitting for the exam. The exact count is specified in MINHERS and confirmed by your Rating Provider. 4. Pass the RESNET national exam. Exam scheduling depends on your Rating Provider's process. 5. RESNET issues your certification. Your name then appears in the RESNET rater directory, the public-facing proof that you are certified. [6]
Take a contiguous week of training, line up field observations quickly, and schedule the exam promptly, and you can sometimes finish in six to eight weeks. Take the online modules part-time and squeeze field days around a full-time job, and you routinely land at four to six months. No Arkansas state agency adds a review period on top, so the timeline is in your hands and your Rating Provider's.
How do you find an accredited Rating Provider in Arkansas?
RESNET's website has a public directory of accredited Rating Providers. [6] Search by state and you will see which providers list Arkansas as a service area. Some are Arkansas-based firms; others are regional or national providers who deliver training online or in nearby states.
When you evaluate providers, ask specifically:
- Is the didactic training in person, online, or hybrid?
- Are field observation days available in Arkansas or do you have to travel?
- What is the all-in cost including exam fees?
- What quality assurance review process do they use after certification?
- How many ratings will they quality-assure for you in your first year?
The quality assurance question matters a lot. After you certify, your Rating Provider must review a percentage of your submitted ratings per MINHERS requirements. That ongoing oversight is how your credential stays valid. A slow or sloppy QA process means your ratings can get held up or flagged. Pick a provider with a reputation for responsive QA, especially in your first year.
For comparison, see how the process works in adjacent states: HERS rater license in Arizona and how to start HERS rater in Colorado show what a well-organized provider relationship looks like.
What equipment does a HERS rater in Arkansas need?
RESNET's MINHERS standard specifies the diagnostic equipment required to conduct a full HERS rating. At minimum you need a blower door system and a duct leakage testing system. [3] In practice, that means:
- A calibrated fan and door panel system (the Minneapolis Blower Door or equivalent) for envelope airtightness testing
- A duct blaster or equivalent for duct leakage testing
- Rating software that is RESNET-approved (REM/Rate, EnergyGauge, or similar)
Arkansas's climate zones, mostly IECC zones 3 and 4, do not require any special equipment beyond that baseline. [7] You are not rating homes in extreme cold where specialized infiltration procedures change the protocol.
Some raters also carry combustion safety testing equipment, which certain program ratings require even if MINHERS does not universally require it for a basic HERS Index rating. If you plan to do utility program work or certify homes under DOE Zero Energy Ready Home, confirm the equipment checklist with that program.
Keep equipment calibration records current. RESNET audits can request calibration certificates, and ratings produced with out-of-calibration equipment can be invalidated. The Energy Conservatory, which makes the Minneapolis Blower Door, offers factory calibration services. [5]
Does Arkansas adopt the IECC, and how does that affect HERS ratings?
Yes. Arkansas has adopted the International Energy Conservation Code. The state enforces the 2009 IECC statewide, though local jurisdictions can adopt later editions. [8] That matters for HERS raters because many HERS ratings in Arkansas exist to demonstrate energy code compliance through a performance pathway.
Under the IECC's performance path, a home can show code compliance by proving its HERS score sits at or below a calculated reference value. The threshold depends on the code edition the local jurisdiction has adopted and how the compliance path is structured. RESNET's software tools can generate an IECC compliance report alongside the HERS certificate, which is what most builders actually want.
If the city or county where you are rating has adopted a later IECC edition (2015, 2018, or 2021), the prescriptive requirements change, and the HERS compliance thresholds may differ. Always confirm with the local building department which code edition is in force before you run a compliance analysis. Get this wrong and you create rework for yourself and the builder.
The Arkansas Energy Office publishes energy code resources and adoption history for the state. [9] That is the right place to confirm current statewide baseline adoption.
Can you rate homes in Arkansas without RESNET certification?
Technically you can produce an energy analysis of a home without RESNET certification. But you cannot call it a HERS rating, you cannot submit a HERS certificate, and you cannot satisfy lender, ENERGY STAR, or DOE program requirements that specifically call for a RESNET-certified rater.
For any transaction involving an FHA or VA loan with an energy efficiency mortgage component, or any ENERGY STAR new homes certification, the documentation explicitly requires the rating to be performed by a RESNET-certified rater. [2] Builders who try to use uncertified analysis for those programs get their applications rejected.
There is also a professional reputation issue. Arkansas builders and building inspectors who have worked with HERS raters know the RESNET credential. Showing up without it signals inexperience, even if your energy modeling skills are solid.
Here is the bottom line. If your goal is to work as a HERS rater in any commercially meaningful sense in Arkansas, RESNET certification is the credential you need.
What ongoing requirements keep your Arkansas HERS certification active?
RESNET certification is not a one-and-done credential. Ongoing requirements come from RESNET and your Rating Provider, not from any Arkansas agency.
Key ongoing obligations:
- Annual RESNET membership renewal. The fee on RESNET's published schedule is $179 per year. [4]
- Continuing education. RESNET requires certified raters to complete continuing education hours each certification cycle to stay current with updates to MINHERS and related standards.
- Quality assurance reviews. Your Rating Provider must review a percentage of your ratings annually. Miss QA review thresholds and your certification can be placed on hold.
- Equipment calibration. Maintain current calibration records for all diagnostic equipment.
Let your RESNET membership lapse and your certification goes inactive, which means your ratings during the lapse period may not be accepted by programs. Reinstatement typically involves paying back dues and completing any missed CE requirements. Confirm the current reinstatement policy directly with RESNET.
For raters who work across state lines (rating homes in Arkansas plus Tennessee or Missouri), RESNET certification travels with you. You do not need a separate credential per state, which is one of the genuine practical advantages of the national framework. [1]

What does the Arkansas HERS rater job market actually look like?
Nobody has solid state-level employment data specifically for HERS raters in Arkansas. The Bureau of Labor Statistics groups energy auditors and HERS raters into the broader energy auditor category (SOC 47-4099), which does not break out Arkansas numbers separately at a useful level of detail. [10]
What we can say from the sector: new residential construction in Arkansas grew steadily through the early 2020s, with the US Census Bureau tracking permit issuance in metros like Little Rock, Fayetteville, and Bentonville. [11] More permits mean more builder demand for HERS ratings, especially as builder programs tied to ENERGY STAR and DOE Zero Energy Ready Home pay rater fees as part of certification costs.
The Fayetteville-Springdale-Rogers metro, driven by the Walmart supplier ecosystem and strong population growth, tends to produce the most new residential construction activity in the state. That is where most new rater business opportunity concentrates. Little Rock and its suburbs are a solid secondary market.
HERS raters in lower-density states like Arkansas often work regionally rather than hyperlocally. A rater based in Fort Smith might cover western Arkansas and eastern Oklahoma. That geographic reach matters when you plan your business model.
If you are weighing whether to enter this field in Arkansas, talking to existing Rating Providers who serve the state is the most reliable market intelligence available. They know where builder demand is and where the gaps are.
Frequently asked questions
Do you need a license for a HERS rater in Arkansas?
No Arkansas state license exists for HERS raters. You need RESNET certification, a national credential administered by the Residential Energy Services Network. Arkansas does not add a state exam, state board, or state application on top of RESNET's requirements. Your RESNET certification is the credential builders, lenders, and energy programs accept in Arkansas.
How much does HERS rater certification cost in Arkansas?
Expect $2,000 to $7,000 in first-year costs depending on equipment choices. Training runs $500 to $2,000 through your Rating Provider. RESNET annual membership is $179. A blower door kit new costs $3,200 to $3,800 from The Energy Conservatory; used units can run under $1,500. Renting equipment lowers upfront cost but adds per-rating overhead. Confirm all fees with your Rating Provider before enrolling.
How long does it take to become a HERS rater in Arkansas?
Two to six months for most people. The training curriculum takes three to five days of instruction. After that, you complete supervised field observations and pass RESNET's national exam. Someone who takes contiguous training and schedules field days quickly can finish in six to eight weeks. Part-time learners balancing a day job typically take four to six months. No Arkansas state review period adds time on top.
What is a RESNET-accredited Rating Provider and do I need one in Arkansas?
Yes, you must train and certify through a RESNET-accredited Rating Provider. These are firms RESNET has approved to deliver training, administer the exam, and provide ongoing quality assurance of your ratings. RESNET keeps a searchable directory on its website. Some providers serve Arkansas through online training with in-person field days; others are based in Arkansas. You stay affiliated with a provider even after you certify.
Is HERS rater certification valid in multiple states?
Yes. RESNET certification is a national credential. Once certified, you can rate homes in any state that recognizes RESNET, which includes all 50 states for standard HERS ratings. Some states like California have layered additional requirements, but Arkansas does not. A rater based in Fayetteville can legally rate homes in Arkansas, Missouri, Oklahoma, or Tennessee under the same credential.
Does Arkansas have an energy code that affects HERS ratings?
Arkansas has adopted the 2009 IECC statewide. Some local jurisdictions may enforce later editions. HERS raters often generate ratings specifically to document energy code compliance under the IECC's performance path. Confirm with the local building department which code edition is in force before running a compliance analysis, because the required HERS threshold varies by code edition.
What equipment does a HERS rater need in Arkansas?
RESNET's MINHERS standard requires at minimum a calibrated blower door system for envelope airtightness testing, a duct leakage testing system, and RESNET-approved rating software. Arkansas climate zones 3 and 4 do not add special equipment requirements. Keep current calibration records for all equipment. Ratings produced with out-of-calibration equipment can be invalidated during RESNET audits.
What is the RESNET national exam for HERS raters?
The RESNET national exam tests your knowledge of building science, the HERS methodology, and the diagnostic procedures required by MINHERS. It is administered through your Rating Provider after you complete training and supervised field work. Exam fees vary by provider, typically in the $100 to $200 range, and are sometimes bundled into the training cost. Confirm the fee structure with your provider before enrolling.
How do I maintain my HERS rater certification in Arkansas?
Renew your RESNET membership annually at $179, complete RESNET's continuing education requirements each certification cycle, and submit to your Rating Provider's quality assurance review process. Keep current calibration records for diagnostic equipment. If your membership lapses, your certification goes inactive and ratings during the lapse may be rejected by programs. Contact RESNET directly for current reinstatement requirements.
Are there any Arkansas-specific programs that hire or require HERS raters?
The Arkansas Energy Office administers state energy programs and tracks energy code adoption. Utility companies operating in Arkansas, including Entergy Arkansas, sometimes run efficiency incentive programs for new construction that reference HERS scores. Builder programs through ENERGY STAR and DOE Zero Energy Ready Home also create demand. Contact individual utility programs and the Arkansas Energy Office to confirm current program requirements and rater participation details.
Can I start rating homes while my RESNET application is pending?
No. You must be a certified RESNET rater before you can issue a HERS certificate. Ratings issued before certification is confirmed are not valid. Some Rating Providers allow provisional or candidate raters to assist on ratings under the direct supervision of a certified rater as part of field observation training, but those ratings must be signed by the certified rater, not the candidate.
What is the difference between a HERS rater and an energy auditor in Arkansas?
A HERS rater produces a HERS Index score for new or existing homes using RESNET's MINHERS methodology. An energy auditor typically inspects existing homes and recommends upgrades, often using BPI (Building Performance Institute) standards. The credentials and tools overlap but are distinct. Some practitioners hold both. For new construction compliance and mortgage program work, HERS rater certification through RESNET is the relevant credential in Arkansas.
How do I find the RESNET rater directory to verify a rater's certification?
RESNET maintains a public directory of certified raters at resnet.us. Builders, lenders, and program administrators use this directory to confirm a rater's certification status before accepting a HERS certificate. If you are a new rater, your name will appear in this directory once RESNET processes your certification, which typically happens shortly after your Rating Provider submits the required documentation.
