Each is a timed online test of original scenarios based on published standards, graded instantly, with a founder-signed certificate and a credential ID employers can verify.

Which Communication & leadership certification should I take first?

Start with a Beginner test such as Critical Thinking Test, Attention to Detail Test, Cognitive Bias Test, then move to Intermediate and Advanced ones such as Strategic Thinking Certification. Every test page shows its difficulty, the skills it covers and a sample question.

Are these Communication & leadership certifications really free?

Yes. Taking a test, receiving the certificate as a PDF and by email, adding it to LinkedIn and having it verified are all free — no course, payment or sign-up.

How long does each Communication & leadership test take?

Quick skill tests are 10, 15 or 20 questions (Beginner, Intermediate or Advanced) at a minute each; full role certifications are 20 scenarios in 30 minutes. Every answer is explained with its source when you finish, and a retake draws questions you haven't seen.

How much do Science of Apps certifications cost?

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.

How are the tests graded?

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.

What happens if I don't pass?

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.

Do the certificates expire?

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.

Can I add the certificate to LinkedIn?

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.

How can an employer verify my certificate?

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.

Are these accredited qualifications?

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.
