1. A. A school year for all public schools in Oklahoma shall consist of at least ten (10) months of four (4) weeks each, during which time school shall actually be in session and instruction offered for not less than one hundred eighty (180) days. Five (5) days may be used for attendance of professional meetings and teachers may be paid for a length of term in excess thereof, under conditions hereinafter outlined. A school district may authorize parent-teacher conferences to be held during a regular school day. Following such authorization by the school district, these conferences shall be counted towards a school day, as defined in Section 70-1-111 of this title, and included as part of the one hundred seventy-five (175) days of classroom instruction. A school district may maintain school for less than a full term only when conditions beyond the control of school authorities make the maintenance of said term impossible and the State Board of Education has been apprised and has expressed concurrence in writing.

2. B. The State Board of Education shall establish criteria for an extended day schedule. The criteria shall:

   1. 1. Prescribe a lengthened school day within limits determined not to be detrimental to quality instruction; and
   2. 2. Ensure that the schedule is equivalent in annual hours of instruction to the one-hundred-eighty-day school year specified in subsection A of this section; and
   3. 3. Be consistent with the provisions of this section and Sections 70-1-110 through 70-1-112 of this title, but may result in fewer annual days of instruction. The State Board of Education may authorize school districts to implement an extended day schedule for instruction pursuant to the criteria developed. The State Board of Education shall require the participating school districts to prepare a report of the impact of the extended day schedule.
