Professional learning certificates are available for workshops as well as online self paced professional learning. You can find all your certificates on studio.code.org/my-professional-learning 

Your self paced certificates will be in the “My Self Paced Professional Learning Courses” section in the Actions column once you have completed the course.  The course is completed when every level is complete (green).

Workshop certificates are available in the “My Workshops” section once you have attended the workshop and the workshop has ended.
