Principal's Message

Mr. Mitchell
Welcome to Spring Semester 2021.  I know you are joining me in the happiness of a New Year.  As we move into 2021, I hope and pray time is taken to prepare ourselves to reap the blessings bestowed on us from the past year.  The year 2020 is definitely something to put behind us, but there was so much learned. It would all be for not if we didn’t somehow grow from it.
 
Moving into the new semester, there are still a few uncertainties to contend with surrounding the pandemic.  So many of us have had to deal with the dreadfulness of the pandemic as it relates to health, work, or everyday lifestyle changes.  I am thankful to be working in a school system that is striving to stay in front of the health concerns and to not put staff and or students in harm’s way.  I so badly want to have a campus full of activity but trust that Distance Learning is the best solution for right now.  We will continue to monitor the data and rely on the guidance of the local agencies as we move through this semester.
 
So many have asked about sports and most importantly senior activities.  At this point, all are to be considered postponed until further notice.  Postponed does not mean “not being planned”. We will be in contact with all student athletes, as well as with seniors, as it relates to Sports and Senior Activities.  I appreciate your patience and cooperation as it relates to things our students so desire and wish to participate in.
 
Our office will continue to stay open for normal business so please feel free to stop by as needed.  To ensure safety for all stakeholders, we will have additional measures in place to eliminate close contact.  If you need technology assistance, please give us a call so we can make the necessary arrangements for you prior to arriving.  If you need assistance with Canvas or Aeries Portal, please give us a call and we will put you in contact with the right personnel to help you out.
 
As we work through changes for second semester, I ask that you review the slightly revised daily schedule.  Please monitor your student’s daily engagement with their classes and make sure they are submitting their work and meeting the daily expectations of all courses.  Please communicate circumstances that may hamper your student’s success and know we are here to assist as needed.
 
Sincerely,
 
Mr. Mitchell
