By Quick answer: What are the best online certifications to get in 2027?
- AI first — Google AI Essentials (under 10 hours) or AWS Certified AI Practitioner ($100 exam) for anyone, in any job.
- Tech entry — AWS Cloud Practitioner ($100), Google Data Analytics or Google Cybersecurity for a first tech role.
- Proven professionals — CompTIA Security+ for security jobs, PMP ($425–$675) for people already leading projects.
- Fast, cheap proof — Microsoft PL-300 for Power BI and Google Digital Marketing for marketing careers.
- Test yourself first — every pick below has a free Science of Apps practice test, so you know you're ready before paying.
Key takeaways
- Pick by the job you want next, not by the badge: a certification is worth what employers in that role screen for.
- Entry certifications that cost $100–$200 or a few months of a Coursera subscription beat expensive bundles for most people.
- Pair a credential with one piece of real work — a dashboard, a lab write-up, a project plan — because that's what interviews probe.
Every January, millions of people type the same question into a search bar: which certification should I get this year? The honest answer for 2027 is narrower than most lists suggest. The World Economic Forum expects workers to see 39% of their existing skills transformed or outdated between 2025 and 2030, and it names AI and big data, networks and cybersecurity, and technology literacy as the three fastest-growing skills.1 The ten certifications below follow that demand. Each is issued by the company or professional body employers already recognise, each can be studied online, and each comes with a free practice test on Science of Apps so you can check your level before you pay a fee.

Each certification, ranked and explained
The order reflects how many people each one helps in 2027: broad, cheap, fast credentials first, then deeper ones that pay off once you have experience.
- CourseraGoogle AI EssentialsAnyone, in any job, who wants to use AI well at work$49/mo Coursera plan
- AWSAWS Certified AI PractitionerNon-engineers who need a proctored AI credential$100
- AWSAWS Certified Cloud PractitionerA first step into cloud, technical or not$100
Google AI Essentials
- Cost
- $49/mo Coursera plan3
- Time
- Under 10 hours (per course page)
The broadest first step for 2027. Google's course teaches you to use generative AI for writing, research and planning at work, with prompting habits and the limits you need to know. It doesn't make you an engineer, and it doesn't try to: it makes you the person on the team who uses AI well. That's the skill hiring managers in every function now ask about.
Best foranyone, in any job, who wants to use AI well at work
AWS Certified AI Practitioner
- Cost
- $1004
- Format
- 90 minutes, 65 questions
The best AI credential with an actual proctored exam behind it. AWS built it for non-engineers — product people, analysts, sales and business roles — who need to talk about machine learning, generative AI and responsible AI with confidence. A $100 exam from the world's largest cloud provider is an unusually cheap, checkable signal.
Best fornon-engineers who need a proctored AI credential
AWS Certified Cloud Practitioner
- Cost
- $1005
- Format
- 90 minutes, 65 questions
Still the most common first cloud certification, and for good reason: it explains how cloud services, pricing and security fit together in a 90-minute exam. On its own it won't land an engineering job; as the first rung before Solutions Architect, or as a credential for anyone selling, buying or managing cloud, it's excellent value.
Best fora first step into cloud, technical or not
Google Data Analytics Professional Certificate
- Cost
- $49/mo Coursera plan2
- Time
- 6 months at 10 hours a week
The most-recommended route into data for people with no technical background. It covers spreadsheets, SQL, Tableau and R through practical case studies. Its value is the portfolio project you finish with, so treat that capstone as the real deliverable and the certificate as the receipt.
Best forcareer changers moving into data with no background
Google Cybersecurity Professional Certificate
- Cost
- $49/mo Coursera plan6
- Time
- 6 months at 7 hours a week
A structured, beginner-friendly path into security operations: Linux, SQL, Python basics, network security and incident response, with hands-on labs. It's a strong start for career changers; pair it with Security+ (next) when you start applying, because many job filters search for that name.
Best forbeginners heading into security operations
CompTIA Security+
- Cost
- Voucher price on the CompTIA store7
- Format
- V7 retiring; V8 adds AI-related risk
The certification that most entry-level security job descriptions name directly, and a baseline for many government and defence-sector security roles in the US. CompTIA is moving from version 7 to version 8, which adds AI-related risk, so check which version you're booking. It's harder than the beginner certificates above, and that's its worth.
Best forapplying to entry-level security jobs
PMP – Project Management Professional
- Cost
- $425 PMI members / $675 non-members8
- Format
- 240 minutes, 180 questions
- Entry
- 3–5 years leading projects (by education) plus 35 hours of training
The gold standard for people who already lead projects. It requires three to five years of project experience plus 35 hours of training before you can sit the 180-question exam, which is exactly why employers trust it. If you don't yet qualify, take CAPM or Google Project Management first.
Best forpeople with 3+ years leading projects
Google Project Management Professional Certificate
- Cost
- $49/mo Coursera plan9
- Time
- 6 months at 10 hours a week
The practical way into project work without the PMP's experience requirement. It teaches planning, risk, stakeholder communication, Agile and Scrum through realistic templates. It also counts toward the training hours you'll need for CAPM later, so it's a sensible first step on a long path.
Best forstarting out in project work
Microsoft Power BI Data Analyst (PL-300)
- Cost
- Exam priced by country10
- Format
- 100 minutes; renew free every 12 months
The most job-relevant certification for analysts who live in Microsoft tools. It tests whether you can prepare, model and visualise data in Power BI and share it securely — what business analysts, finance analysts and operations teams do every week. Microsoft prices the exam by country and renews it free every year online.
Best foranalysts who work in Excel and Power BI
Google Digital Marketing & E-commerce Certificate
- Cost
- $49/mo Coursera plan11
- Time
- 6 months at 10 hours a week
A broad, practical marketing credential covering search, email, social, analytics and e-commerce. It suits career changers and small-business owners best. Experienced marketers get more from platform certifications (Google Ads, HubSpot) and a results-led portfolio, but as a structured first course it's hard to beat.

How to choose the right certification for you
Match the certification to the job you want next, then check what that job's postings actually ask for. A credential is worth exactly as much as the screening filters and interview questions it helps you pass.
- Name the role — write down one job title you want within 12 months, not a field.
- Read 20 job posts — note which certifications appear by name and how often; that's your demand signal.
- Check the gate — some credentials (PMP, CISSP) need years of experience; plan the entry-level step if you don't qualify yet.
- Test yourself free — take the matching Science of Apps practice test to see the gap before you pay.
- Build one proof — a project, dashboard or write-up that shows the skill in use, to talk about in interviews.
If you're unsure where you fit, our guides by profession and by age and life stage narrow the list for you.
Which certifications are worth it, and which aren't
A certification is worth it when employers filter for it, when it teaches a skill you'll use, or when it's the cheapest credible proof of a skill you already have. It's not worth it when it only repeats what your work already shows, or when the exam is so easy that recruiters ignore it.
Usually worth it
- Named in many job posts for your target role (Security+, PMP, AWS)
- Teaches a skill your job is changing toward (AI, data, cloud)
- Costs less than a week's pay and has a proctored exam
Usually not worth it
- Repeats what your degree or experience already proves
- Sold as a bundle of ten badges with no exam
- Requires experience you won't have for years — take the entry step instead
The most common mistake we see is collecting certificates instead of building proof. Three badges and no project lose to one badge and a strong case study.
How much do online certifications cost in 2027?
Most of the certifications on this list cost between nothing and a few hundred dollars. Course-based certificates on Coursera are paid through a subscription the course page listed at $49 a month in November 2026, with financial aid available; how much you pay depends on how fast you finish.2 Exam-based certifications have a fixed fee: $100 for AWS Cloud Practitioner and AI Practitioner, and $425 to $675 for the PMP depending on PMI membership.

The cheapest path that still convinces employers: learn on free material (Microsoft Learn, AWS Skill Builder, Google's free courses), check your level with a free practice test, then pay for one proctored exam.
How we ranked these picks
We started from the skills that labour-market research says are growing fastest — AI and big data, cybersecurity and technology literacy1 — then shortlisted certifications that are issued by the vendor or professional body itself, can be studied online, and have a public price. We ranked them on how many people each helps (entry barrier and cost), how widely employers recognise the issuer, and whether a proctored exam or graded project stands behind the credential. Fees and formats were checked on each official page on 3 November 2026. We'll review this list each quarter of 2027.
Key terms, defined
- Certificate — proof you completed a course; usually graded by the course itself.
- Certification — proof you passed an exam set by an issuer, often proctored and sometimes renewed.
- Proctored exam — an exam watched by a person or software to stop cheating, which is why employers trust it.
- Voucher — a prepaid code you buy to book a certification exam.
Frequently asked questions
What is the best certification to get in 2027?
For most people, an AI certification is the best single choice in 2027, because AI skills now matter in every job. Google AI Essentials is the fastest start, and AWS Certified AI Practitioner adds a proctored $100 exam. If you're aiming at a specific tech job, choose that field's entry credential instead: Security+ for security, AWS Cloud Practitioner for cloud, Google Data Analytics for data.
Which certifications are in highest demand for 2027?
Certifications in AI, cloud, data and cybersecurity, because those are the skills employers expect to grow fastest. The World Economic Forum's Future of Jobs Report 2025 lists AI and big data, networks and cybersecurity, and technology literacy as the top three. Project management credentials such as the PMP remain in steady demand across industries.
Are online certifications respected by employers?
Yes, when the issuer is one employers recognise and the credential has a real exam or graded project. AWS, Microsoft, Google, CompTIA and PMI certifications are widely named in job posts. Employers give little weight to certificates from unknown sites with no assessment, so check the issuer before you pay.
What is the cheapest certification that's worth getting?
AWS Cloud Practitioner and AWS Certified AI Practitioner, at $100 each, are among the cheapest proctored certifications employers recognise. Free options such as Google Skillshop, HubSpot Academy and ISC2's Certified in Cybersecurity training cost nothing to learn. You can also check your level free with Science of Apps practice tests before paying for any exam.
How long does it take to get certified online?
From a few hours to several months. Google AI Essentials takes under 10 hours; AWS Cloud Practitioner usually takes 2–6 weeks of study; Google's career certificates are designed for about six months at 7–10 hours a week. The PMP needs months of study plus three or more years of prior project experience.
Can I get a job with only a certification?
Sometimes, for entry-level IT support, cloud and security roles, but a certification works best with proof you can do the work. Pair it with a portfolio project, a home lab or a work example you can explain in an interview. That combination beats a list of certificates without evidence.
