UI Design Certification

The UI Design Certification is a free, test-based credential from Science of Apps. It certifies that you can design clear, consistent, accessible interfaces — visual hierarchy, typography, colour, layout, components and interaction states. Pass the 20-question, 30-minute test with 75% or more to become a Certified UI Designer (SOA-UID). Every question is based on published standards and research — including Material Design 3 (Google), Web Content Accessibility Guidelines (WCAG) 2.2 (W3C), Maintain Consistency and Adhere to Standards (Nielsen Norman Group) — and each answer is explained with its source.

Read the four skill domains on this page, study the free guides and sources linked to each, then take the 30-minute test online. There is no fee, course or sign-up. Score 75% or more and you get a Certified UI Designer certificate straight away — on screen, as a PDF and by email — with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Material Design 3 (Google); Web Content Accessibility Guidelines (WCAG) 2.2 (W3C); Maintain Consistency and Adhere to Standards (Nielsen Norman Group); Laws of UX (Jon Yablonski); Visual Hierarchy in UX: Definition (Nielsen Norman Group); Understanding Contrast (Minimum) (W3C WAI). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

A UX design certification tests whether you can find and solve the right user problem — research, flows and usability testing. A UI design certification tests interface craft: hierarchy, typography, colour, components, states and responsive layout. Many UX/UI designers hold both.

Yes. The certification is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

It helps you stand out: it shows employers, in a form they can check, that you can apply visual hierarchy & layout and typography & colour to real product scenarios. Add it to LinkedIn and your CV, and back it with portfolio work that shows the same skills — certifications open conversations, portfolios close them.

We rate it Intermediate: assumes hands-on experience in the role. It has 20 scenario questions — 5 from each of 4 domains — and a 30-minute limit. You need 75% (15 of 20) to pass and 90% for distinction.

To get a UI designer job in 2027, show craft that serves users: clear visual hierarchy, consistent layout and spacing, readable type, purposeful colour with accessible contrast, reusable components with every state designed, and screens that work on real devices.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
