Hi Jennifer,

Unfortunately, Khan Academy does not currently have a co-teacher feature, though this article may help provide some workarounds so that multiple coaches can see the same students' progress and some data: https://support.khanacademy.org/hc/en-us/articles/203610350-Can-a-user-have-multiple-coaches-Is-there-a-way-to-add-a-co-teacher

I hope this helps! Please let me know if you have any further questions.
