Become an Assessor

Assessors provide valuable information to homeowners, homebuyers, and renters who are curious about the energy assets – and associated costs – of a home. As energy labeling becomes more influential in the real estate market, stay ahead of the curve and offer this vital information to your clients

2. Work with a Home Energy Score Partner.

Interested Assessors should contact a local Partner or Remote Service Provider for information about joining their program. Or, you can reach out to another organization that is not yet a Partner and ask they become one.

3. Complete the Simulation Training & Test

The Simulation Training and written exam require 8-12 hours of a candidate's time to complete. It can be taken at your own pace or in coordination with a group, if offered by your Partner Organization.

The Home Energy Score Simulation Training ("Sim"), developed by Interplay Learning, teaches prospective Assessors important information about the Home Energy Score. Through the Sim, you conduct virtual, home walk throughs in homes designed to show a variety of situations you might encounter. Understanding the Sim is vital not only to passing the test homes and written exam, but also to performing successful Home Energy Score assessments and producing Home Enery Score reports. 

The Sim teaches candidate Assessors:

  • How the Home Energy Score's Scoring Tool works
  • How to collect relevant data in a standardized way
  • How to explain results to customers

The Sim Training:

  • Is free and online
  • Can be completed at your own pace
  • Has a user's manual and supporting documents to help answer any questions
  • Requires 8 to 12 hours of dedicated time

4. Score a home with a mentor.

Candidate Assessors must score their first home with a mentor. This must be completed within six months of passing the Sim and written exam, and may count toward the quality assurance requirement. Some Partner organizations also offer group or remote mentoring sessions.

5. Start scoring homes!

You are now ready to provide the Home Energy Score to customers. Your Partner organization and the DOE work together to provide talking points, branding materials, and any technical support you need to successfully deploy the Home Energy Score. Be sure to read and download the Assessor Resources for helpful reminders, tools, and tricks you can use in the field.

DOE-trained Home Energy Score Certified Assessors can provide the Home Energy Score within an energy audit, home inspection package, or as a standalone product. You have the flexibility to offer the Score in the way that makes sense for your business.

Assessor Expectations

After becoming a Home Energy Score Certified Assessor, there are certain standards you are expected to meet to keep up your qualification and ensure services are high quality.

  • Quality Assurance. Five percent of homes scored must be re-scored by a quality assurance provider. Re-scored homes should be randomly selected and if data entry errors are detected, Assessors are expected to take action to correct these errors for future assessments. Additionally, if you use a remote quality assurance provider, your first five homes require re-scoring.  
  • Stay Up-To-Date. Assessors receive infrequent yet important email updates from, and Assessors are expected to carefully review these messages.
  • Refresher Course. If you do not use the Scoring Tool for more than six months, you will be deactivated until you pass a short, online refresher course and test to regain access to the Scoring Tool. This can be avoided by using the Tool to score homes on a regular basis.
