Principal's Message

From the desk of Graig C. Mason:

It is with great honor and pride that Ms. Mayorga and I have the opportunity to lead such a dynamic and talented team of educators. Preparing the young scholars of Everett F. Kerr Middle to become the leaders of tomorrow is one of the most important tasks in our society, and it is not one that we take lightly.

In order to accomplish the Cook County School District 130 Mission to: “Provide a well-rounded educational foundation that supports our children's academic, physical, and emotional growth; success; and commitment to others,” all members of the Everett F. Kerr Middle learning community should embody the pillars of a KERR education and be: 


Kindness Empathy Respect Resiliency


Knowledge Empowerment Responsibility Resourcefulness

Everett F. Kerr Middle School is the Heart and Future of the Community

Beyond the pillars of a KERR education, the members of the Everett F. Kerr Middle School learning community believe the following about themselves and all other individuals at KMS:



Essential Valued Encouraged Real Enough Talented Teachable Focused Keen Eager Respected Respectful



Compassion Open-Mindedness Uniqueness Grit Adaptability Reasoning

Perseverance Rationale Integrity Determination Education

When an individual within or impacted by the learning community states that: “I am EVERETT F. KERR,” they are saying:

I am an ESSENTIAL and VALUED member of this learning community. As a result, I am ENCOURAGED to share my thoughts, perspectives, and experiences to assist in the learning, growth, and development of not only myself but of all individuals in our learning community.


I am able to be my authentic and REAL self because that is ENOUGH; I am accepted for who I am as a life-long learner that is still growing and developing. I am naturally TALENTED in my own unique ways, and I can explore and foster my relative strengths and areas for growth further because I am TEACHABLE – learning from all other members of our learning community.


I am FOCUSED on my personal goals and aspirations. As a result, I have a KEEN awareness of my current knowledge and understanding, and I am EAGER in my approach to making meaningful connections to continue my personal learning, growth, and development.


I am RESPECTED in my life-long educational journey because I am RESPECTFUL of others that are also on theirs.

When an individual within or impacted the learning community states that: “I have COUGAR PRIDE,” they are saying:

I have COMPASSION as I meet others with OPEN-MINDEDNESS and challenge my own thinking and understanding. My UNIQUENESS means that I have skills, perspectives, and experiences that I can share with others to help them learn, grow, and develop – and they offer me that same continuous growth opportunity.

I have GRIT that allows me face a wide range of challenges that are part of learning, growing, and developing as an individual. I have ADAPTABILITY to various situations because of my gumption, resourcefulness, ingenuity, and tenacity. Additionally, I have REASONING and thinking skills that allow me to be creative and critical in my approaches to challenges as an individual as well as collectively.


I have PERSEVERANCE to not give up. As a result, I can provide RATIONALE as to why I made the choices I made that will impact my personal educational journey and possibly part or all of our learning community. 


I have INTEGRITY in my interactions with others – honoring honesty and vulnerability as signs of strength that allow me to connect with others that share my DETERMINATION to continuously improve as an individual and member of the greater global community.


I have an EDUCATION that focuses on life-long learning, growth, and development as a person who leads with Kindness, Empathy, Respect, and Resiliency – while simultaneously developing my Knowledge, Empowerment, Responsibility, and Resourcefulness.
