<p>I wasn’t suggesting the onus was on the professor to “certify” the excuses. I was merely giving an example from when one of my kids was hospitalized earlier this year - my kid contacted the professors immediately, but also contacted the dean of students, and the dean of students reached out to the professors as well to indicate they knew the student was hospitalized and could the professor please excuse the absence / extend due dates accordingly. That’s all. </p>
