I found a wonderful resource that has a comprehensive checklist of skills for both the Level 1 and Level 2 Google Educator exams. I would love to say that I created the checklists, but I did not. However, they are great and I regularly follow Eric Curts' blog for inspiration. I also don't believe in recreating the wheel.
So, for those of you that have embarked on the journey towards obtaining your certifications, please feel free to go to the website and use the following checklists:
Google educator Level 1 Skills Checklist
Google educator Level 2 Skills Checklist
Google Level 1 Certified Educator
For those who are interested in learning the basics of the Google apps for education (GAFE), such as Drive, Docs, Slides, Sheets, and Sites. It also helps to give you ideas on how to use the tools together to increase student collaboration and engagement, as well as ease your overall workflow.
