(a) Not later than the 10th day before the last day of instruction in a school year, the board of trustees shall notify in writing each teacher whose contract is about to expire whether the board proposes to renew or not renew the contract. The notice must be delivered personally by hand delivery to the teacher on the campus at which the teacher is employed, except that if the teacher is not present on the campus on the date that hand delivery is attempted, the notice must be mailed by prepaid certified mail or delivered by express delivery service to the teacher’s address of record with the district. Notice that is postmarked on or before the 10th day before the last day of instruction is considered timely given under this subsection.
(b) The board’s failure to give the notice required by Subsection (a) within the time specified constitutes an election to employ the teacher in the same professional capacity for the following school year.
