Principal's Message

Mrs. Prestsater
Happy holidays, AEC Families!
 
We wish you a fabulous winter break doing all the things you enjoy and spending time with the people you love. You have no doubt finished this semester strong and we encourage you to rest up and get ready to start 2nd semester off right.
 
I encourage our students to take advantage of the opportunity to work on their courses anywhere they have a device and an internet connection. It’s important that students are working at home at least two hours a day after school to make progress in their courses.
 
Parents, please continue to monitor grades on Canvas, and communicate with teachers and counselors if you have any concerns. Also, be sure to provide us with your email address and cell phone number if you haven’t already done. Please help by making sure your student is attending each class, every day.   Finally, I encourage you to attend our virtual Coffee with the Principal meetings the first Wednesday of every month. Details are available on ParentSquare.
 
Thursday, December 22, 2022 will be a minimum day for Valley View, CDOHS, and CSOP students with dismissal at 12:25 p.m.
 
Enjoy the winter break, and we look forward to seeing students return on Monday, January 9, 2023.  
 
Finally, we wish you a Happy Holiday and a joyful New Year. Best wishes from all of us at the AEC.
 
Sincerely,
 
Mrs. Julie Prestsater
