Greetings Cavs,

It is hard to believe the end of the school year is here!  We have had an exceptional year here at CAV Nation!  This also provides the opportunity to reflect and celebrate all the achievements in the classroom, activities, and athletics.  Our staff worked extremely hard to prepare our students to be successful and have a memorable year.

We have to stay focused and finish strong the next couple of weeks.  Our CAP Saturday Program continues to be offered for those students that need additional assistance to do well in their classes.  Tutoring is available as well in many subject areas.  Please check with your teachers or Counselor for more information on these programs. 

We will also be administering the Advanced Placement Exams May 4 – May 15. Please see the posted exam schedule.

Our finals schedule is also posted on this site.  Please see schedule as we will have minimum days the last three days of school.

Our Graduation will be on Wednesday, May 20, at 6:30 PM in our beautiful football stadium.  Please come early and watch the incredible Class of 2015 go through their graduation ceremony.

Summer schedule is Tuesday, May 26th – Tuesday, June 30th.  Hours will be from 8:30 am to 1:30 pm.  The first week will be Tuesday through Friday. The rest of the weeks will be Monday through Friday.  There will be no classes on June 4, 5, and 12.

I am so proud of our students and staff for their incredible efforts to make Montclair High School a special place. Of course, we couldn’t do this without the support of our parents and community.  Thank you once again.


Martin Alvarado-Principal
