1. You can share a collection of rubrics with the public by selecting share with: World (Creative Commons License). Your rubric will then be searchable in our "Library" under the "Creative Commons Rubrics" tab.
See our documentation here for sharing collections: https://forallschools.zendesk.com/hc/en-us/articles/205856040-Managing-Collections

2. Another option is to export your rubric, send the CSV file to the teacher you wish to share with, and have them import the CSV file into their account.
