During this challenging time we here at LHS are currently working on ways to ensure all of our students have access to an education. Please continue to monitor teacher websites for additional information. We will also be utilizing SchoolStatus, Remind and/or Microsoft Teams to send out messages of updates as we have them.

Teachers at Desoto County Schools have logged multiple hours or training over the last several days as we migrate to a digital system of relaying information. Many Lewisburg High School teachers have established Microsoft Teams for their classes. This is a system that we have utilized in AP CSP. We respectfully request for you to make sure notifications in Microsoft Teams, whether on a browser or an app and especially if on your cellular device are turned on.

Lewisburg High School's Advanced Placement Computer Science Principles, AP CSP, class curriculum is provided through a scholarship with Amazon Future Engineers. AFE partners with Edhesive to provide the highest consistent level of training there is to offer. You can access Edhesive's site by selecting the image on the right.



You can also monitor your assignments through Twitter, @CoachRoehm, or the calendar here on my teacher page.
