As of the beginning of the 2014–15 school year, the school is currently in year 11 of school improvement and is utilizing the national transformation model for school improvement in efforts to spark student achievement. As part of the transformation model requirements, Jacksonville High School brought in administrators with track records of school improvement with the intention of turning the school around. In addition, the school was granted $5.7 million in a technology grant that has provided the school with interactive whiteboards, student response systems, laptops or tablets, and other classroom technologies for educational use in order to improve student achievement at Jacksonville High School. Furthermore, teachers at Jacksonville High School are being offered extensive professional development and training as part of school improvement. Professional development is centered around literacy and mathematics and is provided through programs such as Advanced Placement training through the AP College Board, Laying the Foundation, and the Literacy and Mathematics Design Collaborative. However, with the advancement of Common Core curriculum and PARCC testing, teachers in all subject disciplines are able to receive training, often at no cost to themselves. The school is currently ranked as the 5th worst school in the state due to low test scores on major end-of-course examinations for Literacy, Algebra I and II, Geometry, and Biology.
