A Letter to Our Families

Welcome from the Superintendent

With great pleasure, I welcome you to NIA, which is a dream come true.

NIA brings together the best and most rigorous curricula of the East and West in a college-prep, open-enrollment, public charter school. It is a safe haven for all students, including those who transition from home schools to a regular school setting. NIA provides a private school environment with no private-school fees. In fact, it is tuition-free! Here students prepare themselves for the 21st-century marketplace, civilization, and wonder in the fields of academics, fine arts, and sports.

NIA is geared toward providing students a balanced and well-rounded education. The classes focus on excellence, innovative learning, and discipline. The dedicated and highly qualified faculty and staff, and the many co-curricular activities, all help our NIA students capture a passion for learning, challenge them to become better, and equip them to face their future as Warriors of knowledge, hope, and love.

At NIA, we believe that every child is gifted, and in partnership with dedicated parents and community, the Academy will help every child reach his or her highest potential. The students of NIA will successfully face the challenges and needs of this nation and the world with the care we show them, the rigorous educational opportunities we provide them, and the character we carefully instill in them.

NIA is the educational home for about 3,000 PreK–12th grade students on campuses in six cities: Arlington, Cedar Hill, Fort Worth, Irving, Mansfield, and Watauga.

Our seats are limited, and enrollment is underway. I encourage you to browse this website and join NIA as it builds students of Wisdom, Stature, and Favor. I invite you to partner with NIA as it develops the whole person for the whole world and impacts the community, nation, and world.
