You can access Sonia here.

Click on “School of Social Work”. On the login screen, select the appropriate role (“Student” is the default), then click “University Sign In”. You will be directed to Columbia’s CAS authentication screen where you will need to input your Columbia UNI (e.g., abc1234) and password.

As outlined above, please make sure to click “University Sign In.” The “Username:”, “Password:”, and “Forgot your password?” options on the Sonia home page will not work.
