The board of commissioners may release any inmate of the industrial school on probation or parole on conditions which the board may prescribe.  If the conditions of parole or probation are violated the board may cause the paroled inmate to be rearrested wherever he may be found and to be returned to the industrial school.  

The board shall provide a system of merits and demerits and shall provide for the unconditional release of the inmates of the school where by the system and by the judgment and discretion of the board it is determined that an inmate has entirely reformed and has definitely earned the right to release; and upon reaching this conclusion the board shall recommend to the juvenile court of the parish the unconditional release of the person.  Upon approval by the court the inmate shall be unconditionally discharged from the industrial school.
