Principal's Welcome

A Word to Parents

It is impossible to overstate the importance of your involvement in your child's education. The hours a student spends in school each year account for only 15 percent of his/her total time. The other 85 percent is spent in your care and under your guidance, nurturing and supervision. If you show your child that a good education is important, you will make a tremendous difference in your child's achievements and attitude toward school.

Mars Area High School is your child's school, it is your school, and it is the symbol of our investment in future generations. The accomplishments of our students become your accomplishments. An excellent school system is our greatest local investment. This is why we ask that parents become partners with the staff at Mars Area High School. Parents are encouraged to:
  • Communicate with teachers by writing and receiving notes;
  • Read the school handbook (available on the District's website);
  • Monitor when homework assignments and projects are due; and
  • Call the school with concerns or issues regarding your child.
As partners, not adversaries, we can collaborate to ensure that Mars Area High School fulfills its primary goal of student learning.
