On November 28, 2005, the Plano Independent School District announced the beginning of an addition of a science wing to assist in increasing Jasper's functional capacity, as the population of the school had already exceeded 2,000 students. The addition was approved in a 2004 Facility Program Bond vote by the citizens of Plano. It was a project given to the Cadence McShane Companies, and was built along with new additions to Williams High School. The addition to Jasper was completed in July 2006, costing the school district approximately $7,501,893. Also added under the contract was a fourth cafeteria line and a multipurpose room. The wooden gym floors were redone during this same time.
