Attention students: Florida Grade 10 ELA Reading, Algebra I & Geometry Summer EOC Retake Information is HERE.

A passing score on both the Florida Grade 10 ELA Reading Exam and Algebra 1 EOC is required to earn a Florida Standard Diploma. Students who have not yet met these requirements are strongly encouraged to participate in the summer retake administration at MHS. In addition, all EOC exams are worth 30% of the final course grade therefore an improved score has the potential to positively impact the GPA. Please Ms. Keenum's S'More for dates. Use the RSVP link to confirm your student's participation.

Summer Reminder for Families!

We know summer has just begun and we hope you’re enjoying every minute! But as we all know, summer has a way of flying by, and before you know it, the new school year will be here.

This is a great time to take care of those important dentist and doctor appointments while schedules are more flexible. If appointments need to happen during the school year, be sure to use our school calendar to help plan visits on days off whenever possible.

Thank you for your continued support of our students—especially when it comes to attendance. You did an amazing job this past year making sure your children were present and ready to learn, and we truly appreciate your partnership!
