County boards of education in fixing the salaries of teachers shall use at least the state minimum salaries established under the provisions of this article. The board may establish salary schedules which shall be in excess of the state minimums fixed by this article, such county schedules to be uniform throughout the county as to the classification of training, experience, responsibility and other requirements.
Counties may fix higher salaries for teachers placed in special instructional assignments, for those assigned to or employed for duties other than regular instructional duties, and for teachers of one-teacher schools, and they may provide additional compensation for any teacher assigned duties in addition to the teacher's regular instructional duties wherein such noninstructional duties are not a part of the scheduled hours of the regular school day. Uniformity also shall apply to such additional salary increments or compensation for all persons performing like assignments and duties within the county: Provided, That in establishing such local salary schedules, no county shall reduce local funds allocated for salaries in effect on January 1, 1990, and used in supplementing the state minimum salaries as provided for in this article, unless forced to do so by defeat of a special levy, or a loss in assessed values or events over which it has no control and for which the county board has received approval from the state board prior to making such reduction.
Counties may provide, in a uniform manner, benefits for teachers which require an appropriation from local funds including, but not limited to, dental, optical, health and income protection insurance, vacation time and retirement plans excluding the state Teachers Retirement System. Nothing herein shall prohibit the maintenance nor result in the reduction of any benefits in effect on January 1, 1984, by any county board of education.
