Clicking My Place, My Alerts, My Progress Reports displays a list of all progress reports that pertain to your academic progress. This list includes midterm grades, final grades, and general progress reports. General progress reports can include commendations (often referred to as "atta-boy" and "atta-girl" feedback) as well as the more common deficiency reports.
Note that some institutions choose not to make final grades available via CNAV. Other schools post grades on CNAV, but only after students have left campus for the semester. Yet other schools post grades the moment that the instructor submits those grades to the registrar and declares them "official". For these reasons, the types of grades that you can see on CNAV and when you can see those grades depends entirely on the business practices of your institution.
