How to Become a Certified Rater
A certified home energy rater must successfully complete training by
a RESNET Accredited Rater Training Provider and must be certified by a
RESNET Accredited Rating Provider.
A rater must successfully complete training by a RESNET accredited
rater training organization. The training is conducted in accordance
with a syllabus developed by RESNET. The training addresses:
- Basic principles of building science (i.e., viewing the home as a
system)
- Thermal resistance of insulation materials
- The minimum rated
features for buildings
- Blower door testing procedures
- Duct leakage testing procedures
- Variations in construction types and their ramifications
- Types and efficiencies of windows
- Types and efficiencies of heating, cooling, water heating, and
lighting systems
- Types and characteristics of space conditioning and domestic hot
water distribution systems
- Types of thermostatic controls
- Determination of azimuth
- Determination of air leakage
- Determination of fuels used by major appliances
- Utility rate structures
- On-site inspection procedures
- Producing a scaled and dimensioned drawing of a home
- Calculating the area of rectangles, triangles, circles, ovals and
combinations of these shapes
- Calculating the volume of boxes, pyramids, spheres, and other
geometric shapes
- Completing a home energy rating checklist or entering data into a
home energy rating software program
- Completing a home energy improvement analysis or entering data
into a home energy rating software program that performs improvements
analysis
- Basic knowledge of financial incentive programs and energy
efficient mortgages
- Communicating the benefits of energy saving measures and practices
to the consumer
- Quality assurance
Each candidate rater must perform two ratings including software
operations, in the presence of trainers.
Certified Raters must also pass examinations that demonstrate a
practical, working ability to effectively use the knowledge and skills
set contained in Section 5.3 of Chapter Two of the national home energy
rating standard to produce accurate and fair Home Energy Ratings. This
examination may either follow training or it may be taken as a challenge
examination.
RESNET National Rater Test
The RESNET National Rater Test is an on-line 50 question true or
false / multiple choice test. The test in open book and raters have two
hours to complete the test. The test is on building science concepts and
rating procedures. Raters receive the results from the test immediately
after completing the test. A passing score is 80%. The test must be
administered by a RESNET accredited rater training provider. A
directory of accredited
rater training providers is posted on RESNET's website. There is a
$50.00 fee to RESNET for taking the test.
A Rater Trainer or Rating Quality Assurance Designee who has passed
the RESNET Rater Trainer/Quality Assurance Test with a score of 90 or
better is considered having met the testing requirement for rater
re-certification.
The RESNET National Rater Test's questions are divided into the key
categories of building science and home energy ratings. The following
are the categories of the test questions and the percentage of questions
in each category that are contained in the test:
- Building Science/Heat Transfer (12%)
- Building Diagnostics (10%)
- Air Distribution Leakage (8%)
- Calculating Gross and Net Areas (6%)
- Definitions/Energy Terminology (6%)
- Energy Units (6%)
- Health & Safety Concerns (6%)
- Envelope Leakage (6%
- Determining Envelope Insulation (4%
- Determining Equipment Efficiencies (4%)
- Potential Comfort Problems (2%)
- Household Appliances (2%)
- Measuring Building Dimensions (2%)
- Understanding Building Drawings (2%)
- Completing Scaled Sketches (2%)
- Ethics and Disclosure (2%)
- Understanding Real Estate Financing (2%)
- ID & Document Features of the Rated Home (2%)
- Specifications (2%)
- Quality Assurance (2%)
- Cooling and Heating Design Tradeoffs (2%)
- Reference Home as Defined (2%)
- Projected and Confirmed Ratings (1%)
- Determining Window and Door Efficiency (1%)
- Building and Durability Issues (1%)

- Program Qualifications (1%)
- Determining Building Orientation (1%)
- HERS Score Computation (1%)
- Major U.S. Climate Zones (1%)
RESNET National Rating Inspector Test
The RESNET Standards includes a category of rater certification
called the Rating Field Inspector. The Rater Field Inspector test will
be open-book, consist of a total of 50 questions with a two hour limit

passing score is 80%.
The following test question categories will be used for the Rater
Field Inspector test:
- Building Science/Heat Transfer
- Building Performance Testing
- Air Distribution Leakage
- Calculating Gross and Net Areas
- Definitions/Energy Terminology
- Health & Safety Concerns
- Envelope Leakage
- Determining Envelope Insulation
- Determining Equipment Efficiencies
- Household Appliances
- Energy Units
- Measuring Building Dimensions
- Understanding Building Drawings
- Completing Scaled Sketches
- ID & Document Features of the Rated Home
- Specifications
- Determining Window and Door Efficiency
- Determining Building Orientation

How the RESNET Rater Test Was Developed
The test was developed over a four-year period using the best minds
in the rating industry. The test is based on the tests previously used
by RESNET's accredited rater training providers. A training committee
composed of representatives of the nation's leading rating providers and
rater training providers including Southface Energy Institute,
Conservation Services Group, Florida Solar Energy Center, Kansas
Building Science Institute, Energy Rated Homes, Northeast HERSĀ®
Alliance, and California Home Energy Efficiency Rating Services spent
three years culling the best questions and weighing their priority among
the categories listed above to write the pool of test questions.
Once the test question pool was developed, RESNET conducted an alpha
test. The alpha test was open to all rater trainers and involved a
review and the ability to comment on all questions. Upon completion of
the beta test, RESNET staff and the RESNET Training Committee reviewed
the comments and reworded a number of questions for clarity, as well as,
replacing some of the questions. Upon the completion of this process, a
professional technical editor was retained to review and edit each
question for consistency and clarity.
After the professional edit of the test, RESNET conducted a beta
test, which every rater was invited to take. Upon completion of the beta
test, RESNET staff compiled those questions that were most often missed
and again, RESNET's Technical Committee reviewed and edited the
questions for accuracy and clarity.
This entire effort was led by Kathy Spigarelli, RESNET's Education
and Training Coordinator. Kathy is an adult education professional and
has over three decades of professional testing experience.
RESNET Rater Test Study Guide Outline
All of the questions in the national rater test were supported by
publications and web sites. It would be good to familiarize or secure
these resources prior to taking the test. The following are the source
documents for the national rater test:
- Builder's Guide, Energy and Environmental Building Association
(EEBA)
- Handbook of Fundamentals, ASHRAE
- Manual J, Air Conditioning Contractors of America (ACCA)
- Residential Energy, John Krigger
- Minneapolis Duct Blaster and Blower Door Manuals, The Energy
Conservatory
- RESNET, especially the links to:
- Energy code compliance
- Energy efficient financing/Fannie Mae product offerings
- 2006 National Mortgage Industry Technical Standards,
especially Chapter 3 and Appendix A
- Formal Technical Interpretations
To assist certified raters to prepare for the national rater test
RESNET has developed a study guide line. To down load the study guide
click on RESNET Rater Test Study
Guide Outline.
In addition to the study guide outline, it is suggest that raters
review the following documents prior to taking the test:
Many training providers supply rater students with training materials
such as John Krigger's "Residential Energy: Cost Savings and Comfort for
Existing Homes" and the EEBA Builder Guide.
Studying these resources
should provider a rater with the information needed to pass the test.
Please remember, this is a national test and may cover topics that are
not addressed in detail in a particular state's program.
If you do not
have a copy of your rating provider's training manual, you should
contact one of RESNET's accredited rater training providers to secure a
copy. Click on directory of accredited rater training providers.
