This National Corrections Reporting Program (NCRP) paper provides technical documentation for constructing prison and post-confinement community supervision (PCCS) terms and term histories, as well as the construction of longitudinal histories linking prison and PCCS term histories together. With this documentation, NCRP data users will have the ability to understand, recreate and combine, if desired, prison and PCCS terms and term histories. Thus, this paper provides details of the algorithm used to process, characterize, and validate terms of incarceration and supervision reported to the NCRP. In the sections that follow, topics include (1) how to identify and tentatively classify terms, (2) how to adjust and refine those tentative terms, (3) how to use prison stock populations (D records) to supplement the datafile, and (4) how to incorporate other adjustments into the final NCRP data.
