There are specific statutes regarding compensation for each office. In general, though, statutes prescribe salaries according to county population classes for many officials. The General Assembly has established 17 population classes for the purpose of determining the compensation of county officers. T.C.A. § 8-24-102. This statute provides base minimum salary schedules for three categories of county officers: (1) "general officers," which include assessors of property, county clerks, clerks of court, trustees, and registers of deeds; (2) sheriffs and chief administrative officers of highway departments; and (3) county mayors. These specified minimum salaries cannot be raised or lowered except through subsequent legislation, but since they are minimum salaries, the actual salary may be increased by resolution of the county legislative body, but the class of general officers must all receive the same amount of any increase.

The minimum salaries are adjusted annually on July 1 by a dollar amount equal to the average annualized increase in state employees' compensation during the prior fiscal year multiplied by the compensation established for the county officials of the county with the median population of all counties. The adjustment cannot exceed 5 percent in any year; provided, however, the annual percentage increase in the minimum compensation of county officials shall not be less than the percentage increase established for county officials of the county with the median population of all counties. The average annualized general increase in state employees' compensation for purposes of calculating the adjustment in salary for county officials means the average increase in base salary plus the equivalent percentage increase represented by appropriated funds made available to address classification compensation issues, plus the equivalent percentage increase represented by recurring appropriation amounts provided to improve the level of retirement benefits, longevity benefits, deferred compensation benefits and other similar benefits not including health insurance benefits. These adjustments are calculated and certified by May 1 of each year by the commissioner of finance and administration. T.C.A. § 8-24-102.

Full-time county officials, not including general sessions judges, who complete the County Officials Certificate Training Program (COCTP) administered by the University of Tennessee's County Technical Assistance Service (CTAS) and become a "Certified Public Administrator" may receive an annual incentive payment up to a maximum of $1,500 from state-appropriated funds. To continue receiving these payments, certified county officials must take additional training annually. If an official receives incentive pay from the state through other professional development programs, such amounts will be offset so that no official receives more than $1,500 of incentive pay from the state per year; provided, however, certified public administrator educational incentive payments to assessors shall not be offset by the compensation received by assessors for obtaining certain professional designations pursuant to T.C.A. §§ 67-1-508; 5-1-310(e). These amounts are subject to annual appropriations from the General Assembly and have not reached the maximum allowed by law.

County legislative bodies may appropriate additional amounts as incentive payments to county officials and employees who have become Certified Public Administrators in an amount not exceeding $3,000 minus payments made by the state. Educational incentive pay received by an official does not affect the calculation of compensation for officials provided in other statutes. CTAS is required to submit a list to the state treasurer, by August 31 each year, of all county officers who have completed all requirements of the COCTP to attain or maintain the designation of Certified Public Administrator. This list replaces individual applications submitted by county officials for purposes of determining eligibility for the educational incentive payment. T.C.A. § 5-1-310.
