Hi Maxon, we don't have that sort of thing here, but you can show everyone your Profile and they will be able to see your badges and other accomplishments.
We currently do not offer certifications for finishing courses, but your badges show your achievements. Many folks show their progress and badges to their employers/schools upon completion. I’d recommend sharing your Codecademy username with potential employers or your school so they can see which courses you’ve finished. You can do this by adding your Codecademy username or link to your LinkedIn account, for example.
Thanks for reaching out,
-Codecademy Community Manager
