We put my daughter on the waiting list at MCOB when she was 3 1/2 because we knew the great reputation this school has. They offer the best in education, they have swimming lessons for all grades during the summer months and the buses drop and pick your child up at your door. They also have a program that gets kids involved with horses! We are so blessed to have our kids at MCOB!!

MCOB is the best! My daughter started in 1st grade, and was behind in everything due to coming from another school. Not only did MCOB help her to get caught up to grade level, but now she is in 6th grade and excelling! Thank you MCOB!

There is a lot I like about the school, but I think the school work should be harder. I like the small class sizes. I like the amount of home work. Compared to East Valley schools I find the school work is behind.

About the tests

In 2011-2012 Arizona used the Arizona Instrument to Measure Standards (AIMS) to test students in reading and mathematics in grades 3 through 8 and 10, writing in grades 5, 6, 7, and 10, and in science in grades 4, 8 and 10. AIMS is a standards-based test, which means that it measures how well students have mastered Arizona learning standards. Students must pass the grade 10 AIMS in order to graduate. The goal is for all students to meet or exceed state standards on the test.

For high schools, AIMS results, AYP status and graduation/dropout rates are used. Schools are identified as Excelling, Highly Performing, Performing Plus, Performing, Underperforming, Failing to Meet Academic Standards or Pending.
