The primary measure of the program is called “Assisted Investigations,” where the number of criminal investigations assisted by CODIS is compiled and recorded. With more than 120,000 documented matches, or positive matches, to profiles in DNA databases, CODIS proves to be an invaluable tool in criminal investigations ("Review of the Federal Bureau of Investigation Laboratory's Forensic DNA Case Backlog", 2010). Additionally, there is a growing trend among local and state governments to require DNA samples to be taken from all suspected offenders, regardless of conviction. This trend is potentially driven by federal grant programs that provide incentives to states that implement an “enhanced DNA collection process” (House of Representatives).,
