Tennessee Code Title 49. Education § 49-5-509

(a) If a teacher transfers from one LEA in this state to another LEA, the LEA from which the teacher transfers shall send to the LEA to which the teacher transfers the results of the teacher's last five (5) evaluations or the results of all evaluations, if fewer than five (5) are available.

(b) A transferring teacher who is tenured or a transferring teacher who is nontenured and has five (5) or more years of prior service shall serve the regular probationary period in the new LEA, unless the local board of education, upon the recommendation of the director of schools, waives the probationary period requirement and grants tenure status or shortens the probationary period.

(c) If a nontenured teacher who does not have five (5) years of prior service transfers to an LEA, then tenure shall not be granted until the teacher has served at least five (5) years when service in both LEAs is counted.

(d) All tenure decisions made under this section are subject to the requirements of § 49-5-504 concerning overall performance effectiveness levels.
