How machinist licensing works — Delaware
How this trade is regulated in Delaware. none-in-pilot-states The framework below describes the national pathway most machinists in Delaware follow.
Machinists are not state-licensed in the United States. Competency is demonstrated through NIMS (National Institute for Metalworking Skills) credentials, employer-administered machining and inspection tests, or completion of a DOL-registered Machinist apprenticeship.
Machinist wages in Delaware · BLS OES A01 2024
Wages are state-level annual figures from the U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics program (A01 2024). Specific machinist earnings in Delaware vary by metro area, employer type, union membership, and years of experience. Verify the current state and metro figures on the BLS OES site (bls.gov/oes).
What this trade actually looks like in Delaware
Delaware machining is small in absolute terms, with most work tied to chemical-process equipment around the legacy DuPont and Chemours footprint, life-sciences and pharma equipment in northern Delaware, and Naval and shipyard-adjacent work in Wilmington. There are no large aerospace primes in-state; most aerospace-grade work is shipped to nearby Pennsylvania or Maryland shops.
Where they work
Wilmington and New Castle County hold most of the statewide machining base, tied to chemical-process maintenance, pharma equipment, and Port of Wilmington-adjacent work. Dover-area shops support Dover Air Force Base contract maintenance. Sussex County in the south has agricultural-equipment and food-processing shops tied to Perdue and other poultry processors. Total volume is small enough that out-of-state employers in Philadelphia and Baltimore draw a meaningful share of the labor market.
Pay context
BLS OES reports a Delaware median of $60,320 for machinists, in line with the broader Mid-Atlantic. Cost of living in northern Delaware sits modestly above the national average; no state sales tax helps the take-home math. Pharma and chemical-process shops typically pay above the statewide median; food-equipment work in Sussex County typically below.
Training pathway
Delaware Technical Community College runs CNC machining programs at the Stanton/Wilmington and Owens (Georgetown) campuses. Polytech Adult Education in Woodside offers short-cycle CNC operator training. Registered apprenticeships in machining are sparse statewide; community college plus direct hire is the dominant entry. Many working machinists in Delaware commute from or to Maryland and Pennsylvania jobs.
Considerations
If you want a Mid-Atlantic location with no state sales tax and access to Philadelphia and Baltimore aerospace and pharma work within a reasonable commute, Delaware is a viable base. If you want statewide depth, programmer ladders, or aerospace specialty work without crossing a state line, Delaware is thin. Verify whether your target employer is in-state or whether the practical commute reaches Maryland or Pennsylvania shops.

STATE LICENSE STATUS
No pilot state (TX, CA, FL, NY, IL) issues a person-level machinist license. The U.S. Bureau of Labor Statistics classifies machinists under SOC 51-4041 and lists typical entry through long-term on-the-job training, apprenticeship, or community-college machine-tool programs (https://www.bls.gov/ooh/production/machinists-and-tool-and-die-makers.htm). Because there is no statutory license, hiring shops typically verify skill through a bench test, print-reading and GD&T questions, and (increasingly) NIMS credential records (https://www.nims-skills.org). ITAR-regulated aerospace and defense shops add employer-specific background and citizenship checks per 22 CFR 120-130; those are job requirements, not state licenses.
NIMS CREDENTIALS
NIMS (National Institute for Metalworking Skills) issues 52 stackable, ANSI-accredited credentials covering Machining Level I, II, and III; CNC Milling and CNC Turning Operator and Programmer; Tool & Die; Mold Making; Stamping; Grinding; and Industrial Technology Maintenance (https://www.nims-skills.org/credentialing). Each credential requires an online theory exam plus a performance/part-inspection component verified by a NIMS-credentialed evaluator (https://www.nims-skills.org). Machining Level I is the recognized entry credential and is used by many registered apprenticeships as a first-year benchmark. NIMS credentials are accepted as Related Technical Instruction (RTI) evidence by many DOL-registered Machinist programs (https://www.apprenticeship.gov). The International Machine Tool Manufacturers Association (IMTMA, https://www.imtma.org) and the National Tooling and Machining Association (NTMA, https://www.ntma.org) both reference NIMS as the industry-standard skills benchmark.
CNC PROGRAMMING
CNC (computer numerical control) programming is the core skill for production machining. G-code and M-code fundamentals (ISO 6983 / EIA RS-274) are the baseline language read by Fanuc, Siemens, Haas, and Mazak controls (https://www.iso.org/standard/34608.html). Most production programs are generated in CAM software: Mastercam (https://www.mastercam.com), Autodesk Fusion 360 (https://www.autodesk.com/products/fusion-360), and SolidWorks CAM (https://www.solidworks.com) are the most commonly listed in BLS machinist job postings (https://www.bls.gov/ooh/production/machinists-and-tool-and-die-makers.htm). 5-axis simultaneous programming is typical in aerospace structural and impeller work and is covered by NIMS CNC Milling Programmer Level III (https://www.nims-skills.org/credentialing). NIMS also offers a stand-alone Job Planning, Benchwork, and Layout credential that is a prerequisite for Machining Levels II and III.
APPRENTICESHIP PATHWAY
The U.S. Department of Labor registers Machinist apprenticeships under RAPIDS occupation code 0296 with a typical term of 8,000 on-the-job-training hours plus 576 hours of Related Technical Instruction; Tool and Die Maker (RAPIDS 0295) typically requires 10,000 OJT hours (https://www.apprenticeship.gov/apprenticeship-job-finder). Community-college Associate of Applied Science (AAS) degrees in Machine Tool Technology are a common parallel or substitute pathway and frequently articulate into NIMS credentials. The International Association of Machinists and Aerospace Workers (IAM, https://goiam.org) represents machinists in parts of aerospace, defense, and rail, though most U.S. production machinists work in non-union shops. NTMA and the Precision Metalforming Association (PMA) both sponsor employer-led apprenticeships registered through DOL.
ADJACENT ROLES
Tool-and-die maker is the most demanding adjacent role, requiring roughly 10,000 OJT hours and tight-tolerance grinding, heat-treat, and fixture-building experience (https://www.bls.gov/ooh/production/machinists-and-tool-and-die-makers.htm). CNC programmer roles split into shop-floor edit/offset programmers and off-line CAM programmers; NIMS CNC Milling and CNC Turning Programmer credentials cover both (https://www.nims-skills.org/credentialing). Manual mill and lathe operator positions are still common in prototype, R&D, and repair shops. Quality-control and gauge inspector roles require formal GD&T training per ASME Y14.5-2018, Dimensioning and Tolerancing (https://www.asme.org/codes-standards/find-codes-standards/y14-5-dimensioning-tolerancing); ASME also publishes Y14.5.1 Mathematical Definition of Dimensioning and Tolerancing Principles. AS9100 (aerospace) and ISO 13485 (medical device) quality-system training are often required before a machinist is cleared to run regulated parts.
