An online application and payment must be submitted by the published application deadline date. Space is limited and applications are accepted on a first-received basis. Examinations may be full prior to the application deadline and may be cancelled due to low enrollment.
Examination fees for eligible applicants are non refundable and may not be transferred to a different applicant. The fee will be returned only if the applicant is not eligible for the examination or if Washington Certification Services cancels the examination. Examinations may be cancelled due to low enrollment.

If an applicant arrives for the examination appointment more than fifteen minutes late there may not be enough time to conduct the examination. In that case the applicant will be required to apply for another examination and pay all applicable fees.
After an applicant is approved and scheduled for the practical examination, one voluntary transfer to a different examination date/location is allowed at no cost to the applicant.
  • Washington Certification Services must receive the transfer request by the published application deadline date.
  • The next examination must be completed no later than six months from the original examination date.
After one voluntary transfer, no additional transfer requests will be accepted. An applicant will forfeit the examination fee if:
  • The transfer examination is not completed within the specific time period.
  • The applicant transfers to another examination but cannot complete that examination for any reason.
Applicants will receive an email confirming our receipt of the online application and payment, usually within five business days. About two business days after the published application deadline date, applicants will receive an email with the examination appointment time and links to helpful online information such as:
  • Directions to the facility.
  • Examination procedures.
  • Study references.
Email addresses must be provided on the examination application. Applicants should add batnews@greenriver.edu to their safe sender list to ensure delivery of confirmations and other important certification information.
