Since ClassSpaces is web-based and ClassSpaces is able to adjust technical resources in the background on demand, there are no limitations for the size of your school.
SIS data and lesson materials uploaded will be stored in the ClassSpaces Cloud so that it is available to you anywhere, at any time.
Currently, ClassSpaces supports Clever and ClassLink SIS. We are working on getting more integrations in place. If you have a SIS you would like us to consider, you can reach out to us at info@classspaces.org.
