Sec. 8. SCHOOL APPORTIONMENT. In making the annual per capita apportionment to the schools, the County Board of Education shall also make an annual allowance out of the State and County Available Funds for the salary and expense of the County Superintendent and such assistants, supervisors and clerical help as he may have, and such expenses shall be pro rated to all of the schools of the county; provided that in making this allowance for county administration, the per capita assessment against the scholastics of the districts shall not exceed $1.50, provided further that the salary of the County Superintendent for the month of September shall not be paid until he presents a receipt from the State Superintendent of Public Instruction showing that he has made all reports required of him. The County Superintendent shall nominate the principals and teachers for the various schools of the county under the supervision of the County Boards of Education, but this nomination shall be subject to confirmation by the district trustees. The district trustees shall have the power and right to refuse to confirm the nomination of the County Superintendent, and when such confirmation is refused, the County Superintendent shall nominate another teacher for such school, provided however, that not more than three nominations of teachers for any one teaching position be made under the provisions of this Section. In the event the district trustee should refuse to confirm the nomination of the County Superintendent as provided herein, the selection of the principal or teachers shall be by joint action of the district trustees and the County Superintendent in which case a majority vote shall prevail.
