The questions come from the New York State Interim Guidance For Higher Education Research During the Covid-19 Public Health Emergency and can be read by clicking on the link at the bottom of the symptom check form.

Answer the questions and click "Submit."

Everyone who returns to campus must sign the University Health Compact, which can also be found in the required online safety training. The app allows you to digitally sign the compact by indicating that you have read it and agree to its terms. Once you select "I Agree," the app will remember our choice.

In future app updates, you will gain the ability to indicate that you have completed training and the required gateway COVID-19 test.

Once you click "Submit," the app will generate a date- and time-stamped 24-hour certificate. Assuming you have no symptoms, this daily pass will be green.


If you answer yes to any one of the questions and receive a red pass, you should not come to work and should notify your supervisor.


Your daily pass is available at all times on the Pass tab found at the bottom of the app screen.
