In today’s world, almost anything can be done online, and gaining a STEM education is no exception.

Online STEM courses offer an accessible and flexible path to obtaining STEM certifications. These certifications serve as evidence for your STEM skills and can either form an alternative, or addition, to studying STEM at university. This alternative route may be ideal for those seeking specialist knowledge from leading universities and organisations but unable to commit to learning at a fixed time and place.

Although some online certification courses are offered by universities, they are not the same as studying a full university degree online. Instead, these courses are shorter and focused on teaching individual skills. This comprehensive guide will help you find and navigate the best online certification courses for STEM.

Best online learning platforms for STEM certifications

As mentioned above, online certification courses are offered by various companies and institutions through different learning platforms. Selecting the right learning platform is as important as selecting the right course.

With the rise in popularity of online certification courses, numerous learning platforms have emerged. While many offer high-quality STEM certification courses, others may fall short in quality. So, how can you know which learning platforms are the best?

Key things to consider when choosing a learning platform:

  • Recognition: The value of your certification can greatly depend on the reputation of the awarding body and the learning platform. Courses offered by well-known universities or reputable companies often carry more weight, especially if you are considering applying to those institutions.
  • Legitimacy: Since many online courses require a fee, it’s important to ensure that the learning platform is legitimate and provides value. To verify the reliability of providers, look for student reviews on sites like TrustPilot, check for accreditation, and consult accreditation bodies like ODLQC, which assess courses to ensure they meet specific standards. Government-funded universities are also generally trustworthy as their courses are government-approved. If you’re still uncertain, seek advice from teachers or career advisors

BEWARE: Fake Credentials!

Just because a course displays an awarding body’s logo or name doesn’t guarantee an official affiliation. It might just indicate a loose connection, or there could be no actual link at all. Some scam courses even create their own accrediting agencies or national bodies to falsely suggest their courses meet certain standards. Research the learning platform, the awarding body, and their accrediting agency, checking they are well-established and have a good reputation.

We have compiled a list of reliable and well-recognised learning platforms to help you choose from some of the best options available.

How do online certification courses work?

This block is currently empty. Please add some content.

STEM online courses fall into two categories based on their structure. Some courses provide immediate access to all content upon enrolment, allowing you to progress at your own pace. Others release content in stages, unlocking new material only after a set time period or completion of specific activities. This gradual-release format can help structure your time better and may be ideal if you find self-motivation and time management challenging.

These courses are often taught through pre-recorded videos (often supported by written transcripts for note-taking), and articles. Some may also host live Q&A sessions or lectures, which, while less flexible, enhance engagement and provide opportunities to ask questions.

Assessment in STEM online courses usually involves end-of-section quizzes that are automatically graded. Smaller, more interactive courses might include written, oral, or practical tasks that are reviewed by a course leader.

Completion of a STEM online course is typically recognised with a confirmation of participation or a certificate reflecting your achievement.

For those seeking more formal qualifications, accredited qualifications such as diplomas or even university degrees are available online. Unlike short certification courses, these programmes are more intensive, requiring a thorough application process, longer-term commitment, and extensive use of the online platform.

7 top tips for online STEM courses

  1. Check for compulsory elements: Look for any mandatory components, such as time limits and required tasks, to ensure you meet all course requirements.
  2. Create a study plan: Even with the flexibility of online courses, having a rough plan for allocating time can help prevent the course from becoming a lower priority.
  3. Supplement your learning: Enhance your understanding by researching and reading additional materials on topics that interest you or that you find challenging.
  4. Apply your learning: After each section, reflect on how the material applies to your job or area of interest, and make a note of this for your CV.
  5. Make your own notes: Since course content may not be accessible after completion, take detailed notes as you go for future reference.
  6. Engage with the community: Participate in forums and social media groups provided by the learning platform to connect with other students and discuss the course.
  7. Share your progress: In addition to adding the course to your CV, consider sharing your progress on LinkedIn to demonstrate your enthusiasm to potential employers.

Are online certification courses free?

Many online STEM courses are available for free, but earning a certificate typically requires a fee. Platforms such as Coursera and edX offer financial aid to help cover the cost of certification. Alternatively, you can take a screenshot of your completion screen as proof of course completion.
Some courses may have participation fees, especially if they cover niche topics not widely available. While this cost might be necessary in some cases, most subject areas have free options. Generally, the quality of free courses is comparable to paid ones, with the key factor for quality being the course’s accreditation rather than its cost.

Top Tip

Look out for courses that have a free trial or “cooling off period”. You don’t have to commit to a purchase unless you’re sure!
