You will begin by mapping your jurisdiction’s criminal code (i.e., all the possible criminal charges that a client could be charged with in adult criminal court) to the NPDWS case types. Each possible criminal charge must be assigned to one of the 11 NPDWS case types.
Step 1: Map Jurisdiction Charges to NPDWS Case Types

In defining the 11 case types, the NPDWS report offers three types of guidance:
(1) descriptions of the types of criminal conduct that fit within each case type,
(2) examples of charges that might fit within each case type, and
(3) sentencing range expected for each case type.
The NPDWS case type definitions appear below.

In your jurisdiction, these three definitions (description, example, sentencing range) may not align for all offenses. A criminal offense might fit the description of one case type, but its sentencing range might fit another. You will need to use your discretion in determining the most appropriate case type. Below are examples of determining case types when definitions do not align.
Example 1: Jurisdiction A defines first-degree burglary as unlawfully entering a dwelling with intent to commit a crime therein and either (1) carrying a deadly weapon, or (2) causing physical injury to any person who is not a participant in the crime. First-degree burglary is punishable by up to 20 years in prison. Under the NPDWS, burglary is an example of a Felony-Low charge. However, the jurisdiction’s maximum possible sentence of up to 20 years in jail matches the expected sentencing range for a NPDWS Felony-High-Other case. In this circumstance, you will have to decide whether to map the charge as a Felony-Mid or Felony-High-Other case, rather than as a Felony-Low. To do so, you must consider both the likely sentence for this charge, as well as how much additional attorney work is involved with the first-degree burglary elements (here, a deadly weapon or bodily injury).
Example 2: In Jurisdiction B, manufacturing an illegal narcotic is punishable by up to 20 years in prison. Under the NPDWS, drug manufacturing is an example of a Felony-Mid charge. However, the maximum possible sentence of up to 20 years in jail matches the expected sentencing range for a Felony-High-Other case. In this circumstance, you should consider the likely sentence for this charge, as well as how much the higher potential sentence increases attorney work on these cases. Based on these considerations, you could map this charge as either a Felony-Mid case or a Felony-High-Other case.
Mapping a jurisdiction’s criminal charges to the NPDWS case types can be a time-consuming task. However, it only needs to be completed once. After it is completed, you will only need to (1) categorize any new charges created and (2) adjust charge categories to account for any statutory changes (e.g., new sentencing range).
Make Conservative Choices About Charge Mapping
If you lack a robust basis for choosing to categorize a charge in a higher case type, you should make the conservative choice and use the lower case type. For example, consider a jurisdiction that has a sentencing range of 10-50 years for certain drug manufacturing offenses. In the NPDWS, drug manufacturing is an example of a Felony-Mid charge. Similarly, a sentence of 10 years would fit the Felony-Mid case type. However, the upper end of the allowed sentencing range – 50 years – fits the expected sentencing range for a Felony-High-Other case.
Assume the provider does not know how often prosecutors seek the higher end sentences in drug manufacturing cases. Also assume the provider does not believe that attorneys do significantly more mitigation or sentencing work when the prosecutor seeks a higher sentence.
Under these circumstances, the provider should categorize all of their drug manufacturing cases as Felony-Mid cases. Making this more conservative choice insulates the workload analysis from criticism of “padding” charges and, in turn, inflating their staffing and budgetary needs. Bluntly, making the conservative choice ensures that the provider is not subject to criticism for being lazy or trying to add unnecessary time.
FAQ: Mapping Charges to Case Types
Absent data on how often prosecutors pursue LWOP murder sentences, your workload calculations should categorize all LWOP-eligible murder cases as less-serious Felony-High-Murder cases, rather than as more-serious Felony-High-LWOP cases. Any written report should note that your estimate of attorney need is conservative — because you did not have the data to separate LWOP cases from non-LWOP murder cases, you counted all LWOP-eligible murder cases as Felony-High-Murder (the less serious case type).
You should consider beginning to track how often prosecutors pursue LWOP in murder cases.
But I want to show how many of our murder cases are LWOP, is there anything I can do?
You could select and review a number of past murder cases to determine how often prosecutors sought LWOP in the selected subset of cases. You could then apply this rate to all LWOP-eligible murder cases to estimate how many cases should be categorized as Felony-High-LWOP. This type of sampling is a well-defined research method. Providers should consult with a researcher to determine the appropriate sample size and other research parameters. If you have a case type identification problem that requires sampling, please reach out to the . Our researchers can offer advice or assistance.
