About the online survey

  • We encourage you to answer all questions to the best of your ability in one sitting. The survey should take about 15-20 minutes to complete.
  • Do not use the browser’s back arrow key to return to previous questions. Use the “Previous” and “Next” buttons located at the bottom of the survey screen.
  • If you are unable to complete the survey in one sitting, you may come back to it later, for up to 3 days. After 3 days, you will need to complete the survey from the beginning.
  • If you need assistance, please call Tricia Christopherson at (206) 667-6563.
