How to Get Certified


Four Steps to Becoming a Certified Rater

  1. Training: Start with our hybrid HERS Rater Training class, comprised of 36 hours of online study and 5 days of classroom and field instruction, during which you will learn the material necessary to pass the RESNET exams and perform two ratings under the supervision of a rater trainer as required by RESNET.
  2. RESNET Exams: During the classroom session, students will take the 50-question national rater exam, the RESNET practical simulation exam, the 25-question combustion safety exam, and the RESCAZ combustion safety practical exam, under the supervision of a rater trainer as required by RESNET. All exams are open book and have a two-hour time limit. Registration for re-taking an exam outside of a training with a local proctor is available through NEHERS.
  3. Supervision of probationary ratings: After passing the examinations and completing two supervised ratings during your training, you must perform at least three more supervised ratings with an accredited HERS Quality Assurance (QA) Provider. To ensure that each new rater is strong in their understanding of home performance, diagnostic testing, and rating software usage, the provider may ask you to conduct some of these ratings and diagnostic testing in their presence and/or conduct more than three ratings under their supervision.
  4. Contract with a RESNET accredited QA Provider: Raters are actually certified by RESNET-accredited QA Providers rather than RESNET per se. RESNET Standards require the QA Provider to perform quality assurance 'desk audits' on a minimum of 10% of all energy ratings, and follow up field inspections on a minimum of 1% of your ratings. These services typically require fees that are paid by the Rater to the QA Provider.
