Western Hills Primary was opened in August of 2000 and is designed to serve PPCD and Pre-Kindergarten through First grade students. Western Hills Primary is a paired with Western Hills Elemetnary, which served the remaining Second through Fifth grade students.

The two schools were once one school, but due to growth, a second school became necessary. Fort Worth ISD bought the adjoining property on Mojave Trail. A vote was made to keep "Western Hills" as part of the school name instead of Mojave Trail Elementary, as the school was referred to in plans. Parents, students, and faculty voted to make WHP school colors blue and silver and the school mascot the Dolphin. The first Principal was Suzanne Etier, followed by Marcia Formby and then Jana Marbut-Ray. The current Principal is Sonya Kelly. 

In the 2007-2008 school year, WHP started the process to become a bilingual school with the dual language program. Pre-K and Kindergarten dual language classes were started and then in 2008-2009 1st grade dual language classes were added.  

Currently Western Hills Primary has about 650 students. Besides the curriculum of FWISD, WHP has special program such as Pet Therapy, Ballet Lessons, Honor Choir, Western Hills High School mentors, Jr. Mint Mentors, TCU mentors, Parents as Teachers, Garden Project and Art Competitions.
