Weekly Message

Good evening, North Garland families!

We are excited to welcome all of our students back beginning next Monday, August 10th. Students can meet their teachers, virtually, this Friday from 9 to 11 am. Students will receive a link in their student email to follow to find their teachers. 

Students will be able to see their schedules in Skyward by Friday of this week. We want all students to check Skyward and communicate any concerns they have to the counselors before Monday of next week.

Due to a District cyber-security concern, we had to cancel all of our digital parent meetings for the week. We do want to address your questions and concerns. Please use this link: to submit any questions or concerns you have. We will then record a video addressing them and release it later this week.

We will begin distributing Chromebooks and internet hotspots this week. Please continue to check your email for updates on when you and your child can come to the school to pick up your devices.

We know that this is not the way we all want to kick off the new school year but we are determined to make it a great year at North Garland High School! Please reach out to us if there is anything we can do to help. 

Thank you,

Michael Arreola
