How Students Can Use These Credentials Effectively

Earning a free STEM certification or badge is only the first step. To maximize the value of these credentials, students (and their parents or teachers) should take the following actions:

  • Add to LinkedIn: Many platforms allow you to share badges directly to LinkedIn. Even if you don’t have an account, you can create one as a student and list achievements under “Licenses & Certifications.” Be sure to include the issuing organization and a brief description of the skills demonstrated.
  • Include in college applications: In the “Activities” or “Additional Information” sections of applications like the Common App, list the most relevant badges with a brief description of the skills mastered. For example, “Earned Khan Academy Calculus I badge (Mastery of derivatives and integrals) – 80 hours of self-study.”
  • Create a digital portfolio: Use a free service like Google Sites, Bulb, or PortfolioGen to compile badges, certificates, and project descriptions. Share the link with teachers or mentors. Organize the portfolio by category (e.g., “Mathematics”, “Computer Science”, “Engineering”) to make it easy to navigate.
  • Print and display: Some platforms (like Khan Academy and Girl Scouts) offer printable certificates or patch ordering. Physical trophies can motivate younger learners. Hang printed certificates in a study area or include them in a binder that shows progress over time.
  • Build a learning transcript: Use a tool like MyCredly or a simple spreadsheet to track all badges earned, including the date, platform, and skills covered. This transcript can be shared with counselors during academic advising.

Beyond individual use, students can also form “badge earning clubs” at school where members work through a certification program together. This fosters collaboration and accountability. Some high schools now award elective credit for earning a certain number of approved badges, so it’s worth asking a guidance counselor about this possibility.
