Each county board of education, city and county board of education, or community college governing board may issue temporary certificates for the purpose of authorizing salary payments to preschool employees whose child development permit applications are being processed. The applicant for the temporary certificate shall make a statement under oath that the applicant has duly filed their application for a permit, together with the required fee, and that to the best of their knowledge no reason exists why they should not be issued a permit. The temporary certificate shall be valid for not more than 90 schooldays and only until the permit originally requested is either issued or denied by the Commission on Teacher Credentialing.
