  • There are several ways to take the REHS/RS exam:
    • At NEHA's annual Education and Exhibition Conference
    • The Yankee Environmental Health Conference in Massachusetts
    • Pearson VUE testing centers (this option, however costs $100 more then the first two). There are many Pearson VUE testing centers throughout Massachusetts and the exam is offered many times throughout the year. If you opt to take the test at a Pearson VUE center NEHA will send you specific login information. You will then be able to schedule the time and place for the REHS/RS exam.
  • Official college transcripts (in a sealed envelope) are required. Contact your college and have an official copy sent to you or have the copy sent directly to NEHA.
