Massachusetts classifies convicted sex offenders into three categories according to their risk of reoffending. Level 1 sex offenders are those least likely to reoffend and information about them is not made public. Level 2 sex offenders are those at moderate risk of re-offending and information about these offenders is made available to residents by completing a request form at the Arlington Police Station.

Level 3 sex offenders are those who are at a high risk of re-offending. State law authorizes police departments to provide community notification of level 3 sex offenders to media outlets, schools, day care centers and other organizations and individuals.

Additional information about the registered level 3 sex offenders in Massachusetts, by city and town, is available at www.arlingtonma.gov/police or www.mass.gov/sorb.
