Welcome our new Principal! Estella B. Cook, a native of Meridian, Mississippi, is in her
22nd year of service as an educator. She began her career as a high school Physics teacher, but also served several middle schools. Mrs. Cook attended Xavier University of Louisiana
and earned a Bachelor of Science degree in Physics with a minor in Mathematics. She then
earned a Master of Education degree in Science Education from Georgia State University.
Mrs. Cook is an innovative, compassionate, respected, and visionary leader. Her focus is always on the students and how education professionals can make a positive impact on
their lives. Mrs. Cook began her career teaching AP Physics and IB Physics at Riverwood
High School, increasing Physics course enrollment by 20%.
Her career goals lead her to Westlake High School, where she served as Science Department Chairperson. Under her leadership, science teachers used data to refine the GHSGT Science preparation program, leading to a 16% increase in students passing in just one year. Mrs. Cook doubled the enrollment of students in Physics classes and helped to increase the
rate of students passing AP science exams by 20%. Mrs. Cook went on to serve as Data Support Specialist at Bear Creek Middle School. With her support, the school received
state-level recognition for its 19% increase in CRCT Science achievement over a one year period. Mrs. Cook also served as Administrative Assistant, Project-Based Learning
Coordinator, and Striving Readers Comprehensive Literacy Grant Coordinator. Through these roles, she had a significantly positive impact on student achievement and engagement, as evidenced by gains in every content area on the last administration of the CRCT. Mrs. Cook then served as Assistant Principal at Westlake High School. In her support of the Math, Science, Magnet, and Special Education departments, Mrs. Cook focused on data-driven instruction through use of common assessments, created a unique master schedule design
for AP STEM courses, and secured professional learning tailored to teachers’ needs. These efforts resulted in an 8-point increase in the school’s CCRPI score from 2014 to 2015.
Mrs. Cook also developed relationships with external stakeholders to benefit students
and staff, partnering with the College Board and Georgia Tech’s Center for Education Integrating Science, Mathematics, and Computing (CEISMC). Most recently, Mrs. Cook
served as Principal of Sandtown Middle School where her leadership has resulted in raising
the school’s CCRPI score to 68.7, the highest score in the past 5 years. In her service to Sandtown, Mrs. Cook raised the achievement of students with disabilities to exceed the
higher state improvement targets for ELA, Math, Science, and Social Studies in all four
content areas in 2018. She sharpened teachers’ skills in designing engaging instruction
through project-based learning and monitoring progress towards meeting standards
through assessment data analysis in professional learning communities.
Mrs. Cook continued her efforts to develop impactful school-community partnerships, increasing the school’s Partners in Education from three to fourteen, including HartsfieldJackson Atlanta International Airport. She also forged partnerships to benefit
students artistically and socially, bringing back the Rialto Center/Georgia State University School of Music Jazz for Kids program and starting the first Metro Atlanta Kiwanis Builder’s Club in South Fulton. Mrs. Cook believes that a highly successful learning environment is achieved by building and supporting a talented and caring instructional team that sets high expectations for all students, establishes clear learning targets, designs engaging and
relevant learning experiences, and collaborates with all stakeholders. With this vision in
mind, Mrs. Cook is honored and pleased to put her passion to work in service to
Oakley Elementary School and the City of South Fulton and Union City communities.
