30 Miss. Code. R. 1501-3.5
After passing both portions of the examination(s), an applicant must pay, within one hundred eighty (180) days from the examination date, the necessary fees to have their credential issued. If the appropriate fees are not paid within the stated 180 day time period, or unless extenuating circumstances for such failure are brought to the attention of the Board and a hearing before the Board is requested, the $225.00 application fee will be forfeited and the applicant will be required to start the application process over by filing a new application with payment of another $225.00 application fee. If any application requirement changes after the applicant has passed the examination but prior to the time their original credential has been issued, the applicant will be required to meet the new requirements prior to the issuing of their credential.
