Unfortunately, at this moment, you cannot have co-teachers in Khan Academy.  

Any idea when it will be available to have co-teachers in KA so both teachers can view and add assignments?  As a co-teacher, it would be much easier to have access so I can help monitor student completion of assignments and assist students needing multiple attempts to complete assignments.

I agree. Is there now an option to add a co-teacher into my KA classes? At the moment, the only way my co-teachers can see student progress is for me to give them my gmail and password.

Wondering the same thing. Now that school's are closed and we are co-teaching from home, can we add a co-teacher to a class? 

This would be so helpful.

Is this available now? I share my class so I am  trying to add a CO-teacher but I can only add more students, and not a teacher... 

I agree with this! When can we add co-teachers to a Khan class? It would be so helpful as we are teaching from different places but still trying to collaborate with each other. 

Is this available now?
