-
What It Is: The standard used by federal statistical agencies in classifying business sectors and industries. Developed with Canada and Mexico, NAICS allows for comparability in business statistics across North American countries.
Who Uses It: Federal and state labor market agencies, economic development organizations, workforce boards, industry associations, economic development agencies, regional planning organizations, sector partnerships, industry consortia, and more.
Why It Matters: NAICS codes are used to label, track, collect, analyze, and publish data related to the business economy. Defines industry sectors allowing an understanding of economic structure and where major activity sits in regions. Businesses may operate across multiple industries while identifying a primary industry of operation. Change agents can use NAICS codes to understand the industry priorities of local businesses. You can explore the NAICS codes through the US Census Bureau. NAICS codes are not assigned; rather companies self-select one primary and potentially multiple secondary NAICS codes. As a result, data may not capture every industrial component within business operations, and some STEMM related operations may be under reported.
How to Interpret It: NAICS codes are formatted as 2- to 6- digit numbers, denoting broad sectors and increasingly detailed industry groups. There are 20 sectors at the 2-digit level and 1,012 national industries at the 6-digit level.
Digits 1-2: Sector
Digits 3: Subsector
Digits 4: Industry Group
Digits 5: NAICS Industry
Digits 6: National Industry -
What It Is: The federal standard used to classify workers into occupational categories based on the work they perform.
Who Uses It: Economic development agencies, regional planning organizations, workforce system stakeholders, sector partnerships, training providers, apprenticeship programs, industry consortia, and more.
Why It Matters: SOC codes are used to label, track, and understand various job-related metrics and outcomes across occupations. SOC codes can be used to understand quantitative and qualitative job information such common skills and duties, typical education at the time of entry, and wage data. You can explore occupation and related learning and training information on O*Net. This data can inform current and future planning by grounding decision-making in local and national data.
How to Interpret: SOC codes are formatted as 2- to 6- digit numbers denoting broad and more detailed occupational groups. There are 23 major groups at the 2-digit level and 867 detailed occupations at the 6-digit level.
Digits 1-2: Major Group
Digits 3: Minor Group
Digits 4-5: Broad Occupation
Digit 6: Detailed Occupation -
What It Is: The taxonomic standard for academic program titles used in federal surveys and state reporting of postsecondary institutional data. Developed by the US Department of Education, each academic program is associated with a six-digit code that is used to identify and track educational programs.
Who Uses It: Higher education institutions, state higher education agencies, IPEDS reporting, accreditation bodies, and more.
Why it Matters: CIP codes are used to label and track many types of participation, outcomes, and other metrics across postsecondary education programs. With knowledge of CIP codes, change agents can understand specific educational programs, while insights like the SOC-CIP crosswalk provide a standardized way to relate academic programs with occupational trajectories.
How to Interpret It: CIP codes are formatted as 2- to 6-digit numbers denoting broad and more specific education programs. There are currently 48 broad subject areas at the 2-digit level and over 1,830 specific instructional programs at the 6-digit level.
Digits 1-2: Broad Subject Area or Primary Discipline
Digits 3-4: Intermediate group or Specialization
Digits 5-6: Specific Instructional program or Exact Major -
What It Is: A national framework developed by Advance CTE to organize career and technical education (CTE) programs into 14 core career clusters. The framework serves as a bridge between K-12 education and industry and allows for consistency in high-quality CTE programs.
Who Uses It: K–12 CTE programs, state CTE offices, Perkins reporting, career guidance professionals, and more.
Why It Matters: Aligns K–12 CTE learning with industry (NAICS) and occupational (SOC), and instructional program (CIP) classification systems, allowing for deeper pathways understandings. The connection between these classification systems can be explored using the Advance CTE crosswalks.
How to Interpret It: There are 14 CTE Career Clusters representing major industry sectors and 72 Sub-clusters denoting more specific career pathways within those clusters.
Description of CTE Clusters:
Advanced Manufacturing: Blends innovative technologies and practices to enhance design and production.
Construction: Focuses on professions involved in designing, planning, managing, and executing projects in the built environment.

Biosciences Sector
Examples of making meaning from system classification landscapes
Exploring classification systems can feel complex. Starting with a specific industry is a helpful way to begin. This section uses biosciences as a practical example. It demonstrates how industry, occupational, postsecondary, and secondary pathway classification codes and data can be connected to make meaning across systems.
Bioscience NAICS Codes
To understand the bioscience sector, SOA is using the Bioscience Innovation Organization’s framework to define the landscape, with the addition of the hospital sector for our working definition. This includes 28 national industries (i.e. 6-digit NAICS codes). Hospitals were added to this definitional framework because, although not traditionally included in biosciences, hospitals employ many STEMM workers and are often amongst the largest regional employers in non-urban communities. Below are examples showing how to decipher two of the NAICS codes and the complete list of NAICS codes used in our working definition of the biosciences industry.
Here is how to interpret two NAICS Codes:
NAICS Code: 325414, Description: Biological Product (except Diagnostic) Manufacturing
2-Digit: 32 Manufacturing
4-Digit: 3254 Pharmaceutical and Medicine Manufacturing
6-Digit: 325414 Biological Product (except Diagnostic) Manufacturing
NAICS Code: 541380, Description: Testing Laboratories
2-Digit: 54 Professional, Scientific, and Technical Services
4-Digit: 5413 Architectural, Engineering, and Related Services
6-Digit: 541380 Testing and Laboratory Services
STEMM and Biosciences SOC Codes
Defining the landscape of “STEMM occupations” is an important component of understanding STEMM learning to career pathways. SOA uses a list of 99 occupations across 8 minor occupational groups, identified based on the technical requirements in each role, their relation to STEMM, and input from labor researchers and industry associations. The list of SOC codes includes medical and healthcare occupations and captures some of the educator workforce that overlaps with research professions. However, because K-12 educators are not typically classified by the discipline they teach they are not included in the dataset at present. Understanding the definitional basis for the occupations being evaluated is an important part of understanding STEMM career pathways.
Below we offer the list of 99 STEMM occupations we use in our analysis and work. We also provide a table showing, within the biosciences industry as defined above, the 20 most common STEMM occupations in the industry across the nation, and the typical level of education upon entering that occupation. This data comes from Lightcast, a third-party data provider that aggregates data from the Bureau of Economic Analysis, Bureau of Labor Statistics, Census, National Center for Education Statistics, state governments, and more.

Bioscience CIP Codes
Using O*Net and the list of STEMM occupations, we can learn more about common educational pathways into those occupations.
Let’s explore instructional programs related to SOC code 19-4021: Biological Technicians. Using O*Net, we can look at the broad subject areas and the exact majors that are common when entering this occupation. At the 2-digit CIP code level, we learn that two broad subject areas are common paths of study:
41 - Science Technologies/Technicians
26 - Biological and Biomedical Sciences
At the 6-digit CIP code level, we learn that there are 19 exact majors/specific instructional programs that are common for people entering this occupation.
41.0101: Biology Technician/Biotechnology Laboratory Technician program
26.0101: Biology/Biological Sciences, General, specific program
26.0102: Biomedical Sciences, General, specific program
26.0202: Biochemistry, specific program
26.0204: Molecular Biology, specific program
26.0406: Cell/Cellular and Molecular Biology, specific program
26.0502: Microbiology, General, specific program
26.0503: Medical Microbiology and Bacteriology, specific program
26.0508: Microbiology and Immunology, specific program
26.0701: Zoology/Animal Biology, specific program
26.0708: Animal Behavior and Ethology, specific program
26.0709: Wildlife Biology, specific program
26.0801: Genetics, General, specific program
26.1102: Biostatistics, specific program
26.1103: Bioinformatics, specific program

26.1302: Marine Biology and Biological Oceanography, specific program
26.1304: Aquatic Biology/Limnology, specific program
26.1501: Neuroscience, specific program
This example shows how you can understand postsecondary learning pathways using publicly available information about occupations you care about.
Bioscience CTE Clusters
Because Advance CTE Career Clusters were established based on industry and occupational alignment, we can use available crosswalks to understand types of K-12 learning opportunities that connect with industries and occupations we care about. Below we use our definition of the bioscience industry – defined by 28 specific NAICS codes – to understand which CTE Career Clusters offer learning that is relevant to the industry. These clusters represent industry relevant pathways for learners at the K-12 level.
