O*NET Hierarchy
The Occupational Information Network, commonly known as ONET, is a comprehensive and systematic database that offers valuable insights into the world of work and occupations. It is a valuable resource that provides detailed information about various occupations in the United States. To understand the ONET database better, we need to delve into its structure and the key elements that define it: minor groups, detailed occupations, and the structure of the code.
Why O*NET?
ONET serves as a vital tool for job seekers, career counselors, employers, policymakers, and researchers. Its primary goal is to provide accurate, up-to-date, and standardized information about occupations and the labor market. This wealth of data assists individuals in making informed decisions regarding career choices, education, training, and job transitions. ONET aids employers in understanding the skills and qualifications needed for specific roles, ultimately contributing to effective workforce management.
Structure of the Code
The O*NET classification system employs a structured coding system to organize occupations. The code comprises four levels of aggregation: major group, minor group, broad occupation, and detailed occupation. Each level of detail identifies a more specific group of occupations.
Major Group: The major group code is the broadest level of classification and ends with "0000" (e.g., 29-0000 Healthcare Practitioners and Technical Occupations).
Minor Group: The minor group code offers a more specific classification, generally ending with "000" (e.g., 29-1000 Health Diagnosing or Treating Practitioners). However, exceptions like "15-1200 Computer Occupations" and "51-5100 Printing Workers" end with "00."
Broad Occupation: The broad occupation code provides a finer level of detail, ending with a single zero (e.g., 29-1060 Physicians and Surgeons).
Detailed Occupation: The detailed occupation code represents the most specific level, ending with a number other than zero (e.g., 29-1062 Family and General Practitioners).
What is a Minor Group?
A "Minor Group" is an intermediate level of classification within the O*NET hierarchy. It acts as a bridge between the broader "occupation group" and the more specific "detailed occupation" levels. Minor Groups cluster closely related occupations based on similarities in tasks, skills, and other essential characteristics. These groupings offer a more detailed breakdown of occupations within an "occupation group," providing a deeper understanding of the distinctions between related jobs. Minor Groups help users navigate and comprehend specific subsets of occupations within a broader occupational category.
For instance, within the "Healthcare Practitioners and Technical Occupations" Occupation Group, Minor Groups could encompass specialties like "Nursing," "Surgery," or "Radiology." This categorization aids in organizing and presenting information about specialized subsets of healthcare occupations.
What is a Detailed Occupation?
A "Detailed Occupation" represents the most specific level of classification within the O*NET hierarchy. It essentially corresponds to individual job titles or specific roles. Detailed occupations furnish comprehensive information about a particular job, including its tasks, required skills, education and training prerequisites, and other intricate characteristics. These detailed occupations are highly specific and encompass various job titles within a broader occupational category.
For example, within the "Nursing" Minor Group, detailed occupations could include titles such as "Registered Nurses," "Licensed Practical Nurses," and "Nurse Anesthetists." Each of these roles carries its unique set of responsibilities, skill requirements, and qualifications.
