Certify'em is a Google Forms add-on that I've been using and recommending for the last few years. Certify'em makes it quick and easy to send personalized certificates to students who pass a quiz in Google Forms. I've also used Certify'em to distribute certificates to people who participate in my webinars and workshops. Last spring the developer of Certify'em added a couple of new features. And for this fall another batch of features is available in Certify'em.
Certify'em now offers gold and platinum plans to go along with the standard free plan. The free plan will continue to allow you to do everything you've been doing with Certify'em including using custom certificates, use in an unlimited amount of Forms, and set minimum passing scores. The only change to the free plan will be the addition of a small "made with Certify'em" mark in the lower, right corner of the certificate. That marking won't start appearing until October 26th.
The gold and platinum plans for Certify'em will remove the Certify'em watermark and give you access to many new features including the ability to edit responses to Google Forms (helpful if a student makes a typo), save copies of all certificates in Google Drive, customize the certificate ID prefix, and provide direct customer support via email.
To be clear, everything that you currently do with Certify'em is still available for free, but you can do even more with the gold and platinum plans.
