What type of summary is shown on the PP73 screen?

The correct choice refers to a summary specifically focused on the offender's drug test history. This type of summary typically includes information about any drug tests that the offender has undergone, detailing results, dates, and potentially the substances tested for. In the context of correctional and probation officer training, understanding an offender's drug test history is crucial for monitoring compliance with court orders or treatment programs. It provides officers with vital information regarding the offender's substance use, which can influence supervision strategies, treatment referrals, and risk assessments.

Other options might cover different aspects of offender management, such as contact histories or treatment referrals, but the PP73 screen is distinctly aimed at providing a comprehensive view of the offender's drug testing records.
