Jian-De Elementary School

Jian-De Elementary was approved for establishment by the Taiwan Provincial Government and Taoyuan County Government on February 1, 1995, with formal instruction beginning in 1998. The campus covers roughly 2.5 hectares and, as of 2023, served over 2,100 students across 74 regular classes plus resource and kindergarten classes — making it one of the larger elementary schools in the district. The school served as a pilot school for Taiwan's nine-year integrated curriculum (九年一貫課程) in 1998–99, and is currently led by its fifth principal, Wu Ming-fang, who has served since 2019.
