A two-track correctional system is one in which two separate institutions operate parallel to each other. One institution administers juvenile justice, while another one administers adult justice. In this case, records from the juvenile system are not shared with the adult one.
I do not believe that a two-track correctional system would work better in our country. Under this system, a teenager with a long criminal record would be tried as a first offender when he reaches the age of eighteen or nineteen. This would be a problem as his past crimes would not be considered. Moreover, this is unlikely to decrease the percentage of offenders reentering the system, as the offenders are more likely to not get the punishment that they deserve. This also means that there is a greater risk of them taking the punishment too lightly and therefore committing crimes again.
