I've built a few Unified Classroom assessments and rubrics that I would like to use in a different LMS. The PowerSchool help pages didn't have any information on how to export items from UC. They had plenty of resources about exporting from PSL courses, but not UC. Please weigh in if you have ideas on how to take the content I've created in UC to a different LMS. I'm not looking forward to recreating UC rubrics and assessments. Thank you for your support.
Since the Unified Classroom is not an LMS but connects to it, I'm sorry to say I doubt there is any tool to export the rubric and use it in another LMS. It is my impression that the migration tool being developed is only from Class Pages to Schoology.
