(a) Within the limitations provided in this section, any aide who agrees to do so shall stand in the place of the parent or guardian and shall exercise such authority and control over students as is required of a teacher as provided in section one of this article. The principal shall designate aides in the school who agree to exercise that authority on the basis of seniority as an aide and shall enumerate the instances in which the authority shall be exercised by an aide when requested by the principal, assistant principal or professional employee to whom the aide is assigned.
(b) The authority provided for in subsection (a) of this section does not extend to suspending or expelling any student, participating in the administration of corporal punishment or performing instructional duties as a teacher or substitute teacher. However, the authority extends to supervising students undergoing in-school suspension if the instructional duties required by the supervision are limited solely to handing out class work and collecting class work. The authority to supervise students undergoing in-school suspension does not include actual instruction.
(c) An aide designated by the principal under subsection (a) of this section shall receive a salary not less than one pay grade above the highest pay grade held by the service person under section eight-a, article four of this chapter and any county salary schedule in excess of the minimum requirements of this article.
(d) An aide may not be required by the operation of this section to perform noninstructional duties for an amount of time which exceeds that required under the aide's contract of employment or that required of other aides in the same school unless the assignment of the duties is mutually agreed upon by the aide and the county superintendent, or the superintendent's designated representative, subject to county board approval.
(1) The terms and conditions of the agreement shall be in writing, signed by both parties, and may include additional benefits.
