You can view different cohorts of your program by going to the top of your Impact Atlas homepage and clicking the down arrow next to the cohort you are viewing. See the picture below:

Once you click the down arrow, the cohorts you have on Impact Atlas will be visible and you can simply click on the one you wish to view.

If you cannot see the cohort you want, you might not have the permission to do so. Please contact your IA administrator for access.
