Court Appearance Notification System

Court Appearance Notification System

Multnomah County

Synopsis: Reminding defendants of upcoming court dates via telephone decreased failure to appear rates in participants.


Community Need

Failure to appear (FTA) in court is a significant drain on the criminal justice system’s resources for every agency. Some accounts suggest that approximately 27 percent of all criminal cases have at least one FTA, which often results in the production of warrants issued by judges, processed by the Sheriff’s Office, and served by various law enforcement agencies. FTAs can also require low-risk arrestees to be jailed until their hearing and can result in additional charges added to the original offense.


The Court Appearance Notification System (CANS) was established in Multnomah County in May 2005, as a pilot program to determine if the failure to appear rate could be effectively reduced. The program was based on the proven results of a program in King County, Washington. Like a doctor’s office, the program worked by telephoning defendants prior to their court hearing to remind them of the hearing’s date, time, and location. This current study is a process and outcome evaluation of the CANS system.


Primary Research Question(S)

Does the use of the Court Appearance Notification System reduce the FTA rate?

Research Design

A quasi-experimental research design was used that consisted of three statistically relevant randomly selected sample groups: those who successfully received calls, those who missed the calls, and a non-treatment comparison group. Researchers analyzed whether there were any significant differences between groups and then examined to see if the defendant failed to attend their scheduled hearings.


The researchers cite several limitations including the study’s quasi-experimental design (as opposed to a more rigorous experimental design) and that the study was based on the first six months of the program before it was given a chance to address some of its issues.


Research Findings

The process evaluation results found that only a fraction of all calls occurred due to a lack of available phone numbers and lack of full program implementation. This limited the full potential of the program.

However, even with limited implementation, the CANS participants’ overall FTA rate was reduced by approximately 37 percent. Those defendants who successfully received notification calls exhibited a 43 to 45 percent reduction in their failure to appear rate over two comparison groups. This resulted in a net cost-avoidance to the criminal justice system of as much as $264,000 in just a half-year of operation.

Main Implications

Making a modest investment in a court appearance notification system results in significant benefits to the criminal justice system and individuals. Defendants more often appear in court, reducing the costs of enforcement and reducing the need to detain defendants in jail for fear of their failure to appear in court. Researchers also issued several recommendations, including increasing the number of available phone numbers of defendants, increasing language accessibility, & placing calls on weekends.
