The Crosswalk Titles sections include titles from three external classification systems related to this O*NET-SOC occupation:
- Military Occupational Classification (MOC)
- Registered Apprenticeship Partners Information Data System (RAPIDS)
- Dictionary of Occupational Titles (DOT)
These mappings are provided as a transitional tool for converting from other classifications to O*NET-SOC. Many times there are multiple external codes mapping to a single O*NET-SOC occupation. There is no data for "parent" O*NET-SOC occupations where more detailed occupations exist. An example is Radiologic Technologists and Technicians (O*NET-SOC code 29.2034.00). The detailed occupations 29-2034.01 (Radiologic Technologists) and 29-2034.02 (Radiologic Technicians) contain the data.
