What is now known as the Juvenile Corrections Center–Nampa began in May of 1994 as a temporary juvenile center to reduce the overcrowding at JCC–St. Anthony. It was funded by the legislature after an Ada County judge ruled that juvenile offenders across the state were being held too long in detention centers before being transferred to JCC–St. Anthony. The Nampa facility was named Juvenile Corrections Center–West.
As a result of collaboration between Ada and Canyon counties a new program based on the Balanced Approach began in the Spring of 1997 and the facility was renamed, Juvenile Corrections Center–Fast Track, and operated out of the then Idaho State School and Hospital campus. In 1999, the Residential Substance Abuse Treatment program following the Therapeutic Community model was developed and implemented, so the juveniles could address both their antisocial and addictive behaviors.
Phase I construction of the Juvenile Management Center was completed in June of 1998. This construction encompassed administrative offices, educational classrooms, a dietary unit, and a medical clinic as well as the observation and assessment unit.
Phase II construction was completed in the fall of 2001 and included additional office space for Juvenile Services Coordinators, District Liaisons, and IT Support Services. Furnishings, staff, and juveniles from the Juvenile Corrections Center–Fast Track building were moved into Juvenile Management Center and the new addition. The name of the facility was changed to Juvenile Corrections Center–Nampa.
Phase III construction was completed July 2008. Solutions, a co-occurring disorder-capable unit, opened for juvenile admission in August 2008. The Solutions unit services 12 female and 12 male adolescents with criminogenic needs who have a mental health disorder and possible diagnosed substance abuse disorder.
