Ala. Code § 16-3-17.3
It is the intent of the Legislature that local school systems be permitted to develop flexible school terms extending over the course of the 12 month calendar year. School systems desiring to use flexible school terms may utilize such scheduling to develop tutorial programs or innovative programs for at-risk students or students deemed academically deficient and to relieve overcrowded classroom conditions. Local school systems desiring to develop flexible school terms shall, upon approval of the local board of education, submit a plan to the State Superintendent of Education and upon his recommendation and approval by the State Board of Education, the plan shall be adopted. No provision of The Alabama Education Improvement Act of 1991 (Acts 1991, No. 91-323), shall be interpreted to require personnel employed in local school systems to work longer than their current contract provides. School personnel may work extended contract periods provided the personnel are willing and are paid commensurate with the system's salary schedule.
