?Frequently asked questions

What is an IT certification?

An IT certification is a credential issued by a vendor or professional body to show that you passed an exam, and sometimes a practical test, on a defined set of skills. Examples include cloud provider certifications, security credentials and project management qualifications.

Which IT certification should I start with?

Pick the one closest to the job you want. Cloud fundamentals from AWS, Microsoft or Google suit newcomers to cloud, CompTIA Security+ suits security beginners, and the Certified Kubernetes Administrator suits platform engineers.

Are certifications worth it?

They help most when they prove skills an employer already asks for and when you pair them with hands-on work. Check job postings for the credentials your target role names before you pay for an exam.

Do IT certifications expire?

Most do. Validity commonly ranges from one to three years, and some renew through a free assessment or continuing education. Check the validity rules on the provider's official page.

How should I prepare?

Use the provider's official exam guide, practise in a hands-on lab, and try a free sample or practice exam where one is offered. Our tutorials and training provider pages can help.

Where do I check exam prices and formats?

Always on the official page for that credential. Fees, durations and exam versions change, so the links here go straight to each provider's programme.

The programme links go to each provider's official certification page, where current prices, formats and renewal rules are published. Links open in a new tab.
