The National Center for State Courts (NCSC) served as the data collection agent for BJS. State-level drug court coordinators provided points of contact for each problem-solving court operating in their state. NCSC combined information from court websites, court-related organizations, news media, press releases, marketing efforts, and related associations to form a comprehensive list of 3,633 problem-solving courts in the United States, Puerto Rico, and Guam.
A court can operate more than one problem-solving court at a single location. In such cases, the Census of Problem-Solving Courts (CPSC) counted each problem-solving court separately. If multiple court locations participated in a single problem-solving court, they were counted as one problem-solving court. Data were collected online and via paper questionnaires. Courts provided information on court type, size, frequency of sessions, issues addressed, services used, participant eligibility requirements, point of entry, benefits to participants, other characteristics of their operations, and case outcomes.
