NAACCR's work is done primarily by which of the following?

• A. staff from comprehensive cancer centers
• B. independent contractors and coders
• C. researchers
• D. various committees, work groups, task forces, and ad hoc groups composed of volunteers.

Answer: (D)

NAACCR's work is driven by volunteers who come together in committees, work groups, task forces, and ad hoc groups. These groups, made up of representatives from registries and cancer programs, develop and maintain data standards, coding guidelines, quality measures, and training resources that shape how cancer data are collected and shared. While staff and contractors support operations and researchers analyze data, the core governance and standard-setting come from these volunteer groups. So the best answer is that NAACCR's work is done primarily by diverse volunteer committees and groups.
