IT certifications can help professionals break into the field, stand out in the competitive job market, and pursue higher-level, lucrative positions. 

Whether you're new to tech and looking for a basic certification or a seasoned pro who wants to receive recognition for your specialized skills and experience, there's a certification for you.

While the best tech certifications are those that serve your experience and career goals, these credentials can help you secure a more lucrative job in IT. Certifications in IT help you tout your skill set so you can vie for raises and qualify for better-paying positions.

On this page, you'll find an exploration of the best tech certifications available in 2021. You'll discover different types of IT certifications, what you'll need to prepare for certification exams, and where to learn more.

What is a certification?

Earning a certification means that you've passed an exam or met the standards of an industry via an assessment process. Certifications usually require some work experience and help you verify your mastery in a specific area. Most aren't connected to an academic institution or degree. 

Certificates in the tech field serve as credit or noncredit-based proof of completion of an education program. Some are offered via colleges or other institutions. They can prepare you for specific careers or further education, or help you develop specialized knowledge. Some certificate programs also award a credential upon completion.

Learners with little or no experience can pursue entry-level certificate programs. However, most certifications require relevant professional experience.

What's the difference between certifications and degrees?

Academic institutions offer programs for degree-seekers. Certifications, on the other hand, come from third-party providers who meet industry-wide specifications. Providers may include research institutes, professional associations, or large corporations such as Amazon and Google. 

Associate and bachelor's degrees often take two and four years to complete, respectively. These programs offer a broad education in a field. Many colleges and universities today offer IT degree programs that also prepare you to sit for IT certification exams.

By comparison, certifications focus on specific skills and build upon experience you already possess. 

Preparation for a certification exam depends on your needs, experience, and how long you choose to study. Every learner is different, but you should plan on 2-4 months of preparation before each certification exam. Some prep programs take up to six months to complete.

Which certification is right for you?

There are dozens of valuable certifications available today, so how do you know which one is the best tech certification for you? Would a certification help you stand out from the crowd or help you prove your IT expertise? There are a few things to keep in mind as you explore options.

First, consider your depth of knowledge and experience. Since certifications are not necessary for every role in IT, find one that will help you expand your knowledge or validate your skills in a particular area. 

Second, does a certification fit your schedule and budget? Certification providers usually offer online, hybrid, and in-person preparation courses. The cost varies among certifications, and not all providers allow you to take the certification exam remotely. 

Tech certification cost

Tech certification costs vary by provider, platform and location. 

Some certification programs charge for study materials and practice exams. Some elearning platforms that host certification prep programs offer a free trial period. 

Depending on the exam fee and whether you pay for prep materials, you can spend $150-$1,200 per certification. Most exam fees are $330-$500.
