A National Incident Based Reporting System (NIBRS) resource page is available to help agencies transition to NIBRS. Some of these resources come directly from the FBI, while others were developed internally during the I-UCR Program’s NIBRS implementation planning phase. This resource page will include updates on NIBRS transition activities when there is helpful information to share. Access the page by clicking on the NIBRS Transition logo at the right-hand side of the page.

Finally, we have established a means for directly emailing the ISP NIBRS Transition Team. Simply click on the email address to the right:
