Welcome Message from
Principal Mastromatteo

Dear GCCHS Families,

Welcome to the 2018-2019 school year. I am excited to be returning as the Principal of Global Concepts Charter High School! I am proud to work alongside such great faculty and staff, and I am excited to work with such an amazing community. As a team, the administration, faculty, community, parents, and students, will work to make positive educational experiences for our students and to support them academically and socially.


According to our District Vision Statement states, “All students will be held to high standards, and will be highly supported to reach and surpass those standards.  The Global Concepts Charter School will be known for an innovative curriculum that prepares students academically, as well as in character, for the world of their future.”  We are committed to providing rigorous curriculum, skilled instruction, engaging technology, and a learning environment that responds to individual student needs. We believe that all students are capable of attaining high levels of achievement.


As a staff, we believe in the unlimited potential of our students by respecting and developing their unique learning styles and interests. We set challenging expectations for performance and support all students to achieve them. We believe in collaboration and communication.  As we embark on the 2018-2019 school year, we are excited at the possibilities for our students.    


Go Gators!

2018-2019 Back Pack Policy


Students will be allowed to bring any back pack they choose to school. If it is not clear it must go into their locker for the day. If a student would like to carry his or her back pack throughout the day, it must be clear. Students are able to go to their lockers in between class periods to get any needed supplies. Students will be allowed to carry small purses/bags (approximately the size of a tissue box). This is being done as a preventative safety measure for students and staff.
