Employment and Wage Data Sources

¹Employment data come from the Washington State Board for Community and Technical Colleges (SBCTC) and reflect WA/OR employment for students enrolled at BTC between 2016-17 and 2018-19. Students are included in the employment rate if they left with a credential. Rates are not shown for programs with fewer than 10 students meeting the above criteria.

²Wage data come from Washington State Employment Security Department (ESD) 2020 Occupational Employment and Wage Estimates (Washington State wage) and reflect 2015-2018 employment. Wage data represent occupations that BTC faculty have identified as the most relevant career paths for program graduates. Note that these wages reflect employees with varying educational levels/credentials. For cases in which multiple occupations have been identified by faculty, a weighted percentile is calculated using each occupation’s percentile wage and employment size estimate. Wages are not shown for programs for which occupations do not meet the ESD’s minimum thresholds for publishing. If the program has wage data from the Washington SBCTC that involves shift work, these ESD wages reflect the same number of hours used in the annual wage calculation. Starting wage = 25th percentile, median wage = 50^th percentile, wage potential = 75th percentile.

Program Outcomes

Demonstrate competency in their ability to operate machine shop equipment: lathes, mills, grinders, and drills
Demonstrate competency in their ability to read and interpret blueprints per industry standards
Successfully demonstrate their ability to process and plan a piece part through the lab until completion
Demonstrate competency in CNC machine tool operation and programming
Demonstrate competency in CAM design and manufacturing

Employment Outlook

Employment of machinists is expected to increase and employment of CNC operators is expected to increase. About 82 percent of program graduates are employed within nine months of graduation. The average annual wage in this field is $59,155, with an earning potential of about $90,542 per year.*

Criminal convictions may restrict or prevent student participation with internships and employment in this industry.

Although most program graduates work as machinists, with experience, graduates can advance to positions such as journey level machinist, tool programmer, CNC operator/programmer, manager, engineer and machine and shop tools sales and service representative.

In addition, some graduates are self-employed. Around the country, most machinists work in small machining shops or in manufacturing firms that produce durable goods, such as metalworking and industrial machinery, aircraft, or motor vehicles.
