Our school experienced rapid growth since its establishment in 1981 when the student population was 112. There was initial steady growth with the student population stabilising and averaging 590.  In 1989 and 2004, the student population exceeded 610 when the school had four kindergarten classes. With the change of structure of class sizes in Kindergarten, Year 1 and Year 2, the Department of Education and Planning installed two new "permanent" classrooms (MDR) in 2004.  Since then, the student population has increased to 670

Despite the school's humble beginnings on an all-demountable site (1981-86), there has been strong development of high academic standards, pride in the school's achievements, pride in the school's appearance and magnificent community involvement and support.

Kings Langley Public School can now be considered a showpiece for public education. A new school with modern facilities was built at the current site in 1986. The buildings and surrounding grounds are attractive and well-maintained. The school prides itself on further improvement to this environment in order to provide the optimum learning conditions for its students.
