Tennessee Code Title 40. Criminal Procedure § 40-28-117

(a)(1) Parole being a privilege and not a right, no prisoner shall be released on parole merely as a reward for good conduct or efficient performance of duties assigned in prison, but only if the board is of the opinion that there is reasonable probability that the prisoner, if released, will live and remain at liberty without violating the law, and that the prisoner's release is not incompatible with the welfare of society.  If the board so determines, the prisoner may be paroled and if paroled shall be allowed to go upon parole outside of prison walls and enclosure upon the terms and conditions as the board shall prescribe, but to remain while thus on parole in the legal custody of the warden of the prison or the supervisor of the county jail or workhouse from which the prisoner is paroled, until the expiration of parole.  The terms and conditions of parole set by the board may specifically include the requirement that a prisoner pay restitution to the victims of the crimes for which the prisoner had been sentenced to prison, to compensate them for their personal injuries or property losses or both proximately caused through the commission of those crimes.

(1) Prisoners serving an indeterminate or determinate sentence with a maximum term of two (2) years up to ten (10) years inclusive, as fixed by the court, shall be paroled by the board ninety (90) days prior to the completion of the maximum term of sentence less credit for good and honor time and incentive time;

(2) Prisoners serving a determinate or indeterminate sentence with a maximum term of more than ten (10) years as fixed by the court, shall be paroled by the board six (6) months prior to the completion of the maximum term of sentence less credit for good and honor time and incentive time;

(3) All prisoners mandatorily paroled shall be paroled under the provisions and conditions as the board may deem necessary.  A violation of the provisions and conditions shall subject the prisoner to all the penalties and provisions of law now provided for violation of the terms of parole.  Upon a violation, the prisoner shall not receive another mandatory parole, but may be paroled in the discretion of the board;

(4) Mandatory parole shall not be construed to grant parole earlier than set forth in §§ 40-28-115 -- 40-28-119;

(5) Every prisoner released on mandatory parole shall receive a money and clothing allowance, as set out in § 41-21-219, for prisoners released on parole;  and

(6) Prisoners who have been convicted of a sex offense shall not be released on mandatory parole unless they have been evaluated and met the requirement described in § 40-28-116(a).
