Am I Ready for the Future?

This text will be replaced

It is hard to believe we are beginning our second semester.  We have hit the ground running with our students getting a fresh start in their classes. Students and staff and are excited full of renewed energy!

Our school will recognize students that excelled during the first semester and will also continue to support all of our students for academic achievement. We continue to provide opportunities for our students through the infusion of additional technology in the classroom. 

All students are encouraged to attend our tutoring programs after-school Monday through Thursday.  Also, our Saturday School program will continue to provide extended learning opportunities for our students.  I encourage parents and students to continue to use School Loop to communicate with teachers, counselors and administrators to monitor progress and success.

Please keep in mind that it is critical to attend school and be on time every single day.  We are here to provide the best educational experience for all of our students as we prepare them for college and careers!

I look forward to seeing you on campus and various school events. Please don’t hesitate to call with any questions or concerns.
