A document that many employers use to identify worker applicants' qualifications for employment?

• A. Portfolio
• B. Resume
• C. Reference list
• D. Cover letter

Answer: (B)

A concise summary of your education, training, and work experience that employers can scan quickly is what a resume provides. This is why it’s the document employers commonly use to identify applicant qualifications. A resume highlights your most relevant qualifications—like schooling, certifications, technical skills, and job history—so recruiters can assess fit at a glance, often in just one or two pages. In additive manufacturing, you’d tailor it to include your hands-on experience with 3D printing processes (such as FDM, SLA, SLS), relevant software (CAD, CAM, data handling for STL/3D models), equipment you’ve operated, materials you’ve worked with, and any certifications or safety training that demonstrate readiness for the shop environment and quality standards.

Portfolios are valuable when you need to show concrete samples of work, especially for roles focused on design or prototyping, but they’re typically used to supplement a resume rather than replace it. A reference list provides people who can vouch for you, which is important for verification, but it’s not the primary document employers rely on to gauge qualifications. A cover letter introduces you and explains why you’re interested in the job, adding context, but it doesn’t present a concise snapshot of your qualifications the way a resume does.
