Google provides several possible certification options for educators including Educator Level 1, Educator Level 2, Trainer, Innovator, and Administrator. Of these, Educator Level 1 and 2 are the place to start and are especially designed for teachers and other educators in a school setting.
To earn the status of Google Certified Educator Level 1 or 2 you need to take an online exam that shows your practical knowledge of using Google Apps for Education in a school setting, as well as demonstrate your ability to perform many tasks within the Google Apps suite of tools.
