Three subsystems of the correctional system serve different types of prisoners: those sentenced to more than 3 years, those sentenced to 6 months to 3 years or with pending cases, and those with lesser sentences. To minimize use of the criminal justice system, citizens are encouraged to use informal dispute resolution at the community level (barangay). To limit the length of incarceration, the Philippines also uses absolute pardons, conditional pardons, commutations of sentences, amnesty, parole, and good conduct allowances. Correctional facility rules are designed to allow prisoners to develop personal and social relationships. A centralized jail system has improved control over the nation's jails. Special programs and four residential facilities provide services for youth development and for youths with special needs. Several task forces and committees have proposed changes, including the establishment of a national organization to administer all correctional institutions, a more liberal system of release on recognizance, and the decriminalization of victimless crimes.
