When you're hiring a graphic designer or design agency, credentials matter—but not all certifications carry equal weight, and formal training doesn't always guarantee you'll get the results you need. Learning what credentials actually predict quality work helps you separate designers who've invested in real skill-building from those who've just collected certificates. This guide breaks down what to evaluate so you can confidently compare and hire the right designer for your brand.
Why Designer Credentials Matter (But Aren't Everything)
A graphic designer's portfolio tells you what they've produced; their education tells you what foundations they built on. Certifications prove they've met specific benchmarks—like Adobe Creative Suite mastery or UX/UI design principles—while formal degrees often indicate broader knowledge in color theory, typography, and design history. The catch: a self-taught designer with a stellar portfolio may outperform a degree-holder whose work is stale. Credentials are one data point, not the whole picture.
Key Certifications Worth Checking
Adobe Certified Associate (ACA) credentials demonstrate hands-on proficiency in Photoshop, Illustrator, InDesign, or XD. These are relatively straightforward to verify and confirm the designer knows the core tools your branding or marketing materials will likely need. Expect to pay a premium for designers holding multiple Adobe certifications.
Google UX Design Certificate (from Google Career Certificates) is increasingly common and signals training in user research, wireframing, and interaction design—critical if you're hiring for website or app design work rather than print collateral.
Graphic Design degree (2-year Associate or 4-year Bachelor) indicates broader training in design history, composition, and creative problem-solving. Designers with formal education typically charge $75–$150+ per hour, while entry-level certified designers may charge $35–$75 per hour.
Look for credentials from institutions like AIGA (American Institute of Graphic Arts) or design bootcamps like General Assembly and Interaction Design Foundation. These institutions maintain reputations, which means completing their programs signals genuine capability.
What to Actually Verify
Don't just take a designer's word for it—ask to see certificates or verification. Many Adobe certifications are listed publicly on Adobe's credential verification portal. For degrees, ask for transcripts or confirmation of graduation; it's a simple ask that most legitimate designers expect.
Check if their credentials align with your project type. A UX designer with Google certification is gold for app design but may be overkill for a simple logo refresh. A print designer with certification in color theory and typography matters more for a luxury brand's packaging than someone trained primarily in web design.
Review portfolios specifically for work similar to yours. A certified designer's credentials mean they have foundational skills; their portfolio proves they've applied those skills in your industry or style.
Comparing Design Service Providers
When evaluating agencies or freelancers on platforms like Mercoly, you can compare and find trusted graphic design services providers in one place—check their team credentials, client reviews, and past work side-by-side.
For agencies, verify that the designers who'll actually work on your project hold relevant certifications, not just the founder. A 10-person design studio might have one Adobe-certified lead and junior designers still learning; clarify who does what.
For freelancers, cross-reference their stated certifications with their online presence. LinkedIn, Adobe portfolios, or personal websites often list certifications. If they claim credentials but can't point you to them online, that's a red flag.
Red Flags vs. Green Lights
Green lights: A designer shows recent certifications (renewed within the last 2–3 years), relevant education, and a cohesive portfolio demonstrating growth over time.
Red flags: They claim credentials they can't verify, their portfolio doesn't match their stated specialties, or they dismiss formal training as unimportant while showing technical gaps.
Frequently Asked Questions
Q: Does a graphic design degree guarantee better work than a self-taught designer? No—a degree provides stronger foundational knowledge, but a self-taught designer with real client experience and a proven portfolio can deliver equally strong results. The degree matters most if the designer is early-career and lacks extensive portfolio evidence.
Q: How much should I pay for a certified vs. non-certified graphic designer? Certified designers typically charge 20–40% more ($50–$150+ per hour or $2,500–$10,000+ per project) due to verified skill and market credibility, but price alone doesn't guarantee quality. Evaluate their portfolio and client reviews alongside credentials.
Q: Should I hire an agency or freelancer, and does certification matter differently for each? Agencies often employ certified designers and offer team support, which justifies higher rates ($5,000–$50,000+ for full branding projects); freelancers are flexible and cost-effective but rely on individual credentials. Check certifications for whoever will directly work on your project.
