The Common Core State Standards Overview

Dear Montclair Cavs!


The 2014-15 school year is off to a great start! We will continue to offer the many support services and opportunities for our students to be successful.  Tutoring is available for many courses and we will also offer freshman specific tutoring opportunities. Our online credit recovery courses will be offered before, during, and afterschool! Our goal is to offer extended learning opportunities for students to be successful and maximize their potential. Students can see their Counselor for additional information regarding these programs. Our goal at Montclair is to provide our students with a world class education and have them College and Career ready when they graduate.

Montclair offers nineteen sports, many extra-curricular activities, and over fifty clubs in which students can be involved. Students who become involved outside the classroom are more successful inside the classroom.  Club rush week begins the week of August 25th. Cavalier spirit is through the roof as demonstrated in our back to school rally on our new football field!  Our fall sports will begin the week of August 25th  with our first varsity home football game vs. San Gabriel on August 29th at 7:00 pm.  Come join us and see the recent upgrades to our football field!

I am honored to work with our tremendous staff and Montclair community as we prepare our students for the 21st. century.   

I am looking forward to seeing you at our events and activities!
