Hi there,
Thank you for your message! This depends on the course or training you're taking with us. For instance, if you are taking the CDA with CLASS Course, you will not need to activate a product key to begin your course, but if you are recertifying for your CLASS Observer Certification, you will. If you are unable to locate your product key, please don't hesitate to reach out to us at
contact@teachstone.com - thank you!
Best,
Allison
