1. In addition to all other qualifications imposed by law, it shall be a qualification of the office of assessor that he shall, no earlier than his becoming an assessor-elect and no later than the second anniversary of the date of his commencing a term of office, attend a course of study concerning the assessment of ad valorem property taxes and thereafter be certified by the commission. Assessors appointed to office on or before January 1, 1981, shall attend such course of study within two years of January 1, 1981, and thereafter be certified by the commission.

2. Upon notice by the provider of the courses to the commission that an assessor or assessor-elect has attended such a course of study, the commission shall issue a certificate of attendance to the assessor or assessor-elect.

3. The commission shall set, as a minimum for each course of study, classroom time totaling thirty-two hours. The commission shall develop course listings which meet the requirement of this subsection and have continuing authority to modify and supplement such list.

4. To remain certified as provided in sections 53.250 to 53.265, each assessor must, within each two-year period after certification, attend at least one additional course of study approved in the manner provided in subsection 3 of this section.

5. Nothing contained in sections 53.250 to 53.265 shall be construed to require that an assessor or assessor-elect pass a written or oral examination upon the subject matter of the ad valorem course of study, but in all cases attendance at such course of study shall be sufficient qualification for office and additional compensation within the provisions of sections 53.250 to 53.265.

6. Upon written notice by the commission that an assessor has failed to properly comply with the provisions of sections 53.250 to 53.265, the state director of revenue shall immediately suspend payments of assessment costs by the state under sections 137.700 and 137.710 to the county in which the assessor is serving until such time as the assessor complies with sections 53.250 to 53.265, resigns from office, is removed from office by appropriate legal action, or until his successor in office is qualified, whichever comes first. The withholding of state funding under sections 137.700 and 137.710 shall not be construed to be the exclusive remedy against an assessor who fails to qualify for office under this section, but other remedies provided by law shall be available.
