The investigation and classification system forms the foundation of prison operations. It ensures that new inmates are scientifically assessed and analyzed, and then assigned to appropriate levels of security management and treatment programs in alignment with the principles of individualized sentencing.

Moreover, modern prisons emphasize the functions of education and rehabilitation. Therefore, new inmates undergo thorough investigations—both direct and indirect—based on various factors such as age, temperament, education, vocational skills, health, religious beliefs, and criminal history. Psychological tests are also used to evaluate their individual differences and characteristics, helping to develop tailored treatment plans.

This process collects a broad range of data and establishes scientifically grounded, individualized case profiles, which facilitate more effective inmate treatment and management.

In addition, prior to reintegration into society, inmates are reviewed and assisted in applying for rehabilitative protection. Their families are notified in advance so they can prepare to receive them, and community organizations are coordinated to provide early reintegration counseling.

For elderly, seriously ill, or physically and mentally disabled inmates without family support, the prison refers them to social welfare organizations to address their post-release living needs. If necessary, the prison also invites community organizations to discuss reintegration and support services, in order to connect them with the social safety network, promote social adaptation, and prevent recidivism.
