BJS collects data on various criminal justice domains being researched by NIJ, and the Bureau of Justice Assistance (BJA) administers grant programs whose effectiveness must be measured by NIJ-funded evaluation research; research on chronic, repeat victimization is cited as an example of such partnerships. Regarding partnering with BJS, it makes sense for the statistical systems developed and maintained by BJS to be informed by the data needs of research being funded by NIJ. Also, BJA funds innovative programs in the field whose outcomes and performance must be measured with evaluation research to determine whether further investment and replication are warranted. This interagency cooperation was illustrated in a recent joint seminar series launched by BJS and NIJ. The first speaker in the series was a visiting fellow with BJA who discussed her work on chronic victimization (being victimized multiple times). In the Q&A session, participants from BJS and NIJ staffs focused on how to improve statistical systems related to criminal victimization, as well as how to use ongoing research and evaluation to inform efforts to address chronic repeat victimization.
