Fees are payable to the Oregon State Board of Geologist Examiners (or OSBGE). 

Application fees are non-refundable.  Exam fees are generally non-refundable except when a candidate applied for but was not approved by the Board to sit for exam.  No refunds of exam fees are provided to candidates that withdraw from or do not appear for exam regardless of the circumstances.  

A candidate may be able to forward exam fees to the next exam administration upon written request to the Board but only when such request is received by the Board prior to the date specified in the Board’s exam approval letter.  However, the candidate must then take the examination within one year from the date of initial Board approval or will have to reapply.
