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 Home Energy Score Simulation Training ("Sim") teaches prospective Assessors important information about the Home Energy Score. Through the Sim, you conduct virtual home walk throughs designed to show a variety of situations you might encounter. The Sim 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. Access to the Sim is only availble after joining a Partner's program. 

Watch the short Sim overview video to find out more.

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. 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.

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.

6. Meet ongoing expectations

After becoming an Assessor, there are certain standards you are expected to meet.

  • 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.
