Chenggong Elementary School

Chenggong Elementary was founded in November 1964, originally named "Gangdi National School," to serve children of Gangdi Village who previously had to travel far to attend Shagang Elementary School. It was renamed "Gangdi National Elementary School" in 1968, then took its current name, "Chenggong Elementary," in 1974 — the same year Gangdi Village itself was renamed Chenggong Village following completion of the Chenggong Reservoir. Enrollment has declined over time, from 217 students in 1967 to about 49 students by 2008.

成功國小創立於民國53年（1964年）11月，初名「港底國民學校」，設校目的是服務港底村的學童，過去他們須遠赴沙港國小就讀。民國57年（1968年）改名「港底國民小學」，民國63年（1974年）隨著港底村因成功水庫完工而更名為成功村，學校也同步改名為「成功國民小學」。在學人數逐年減少，從民國56年（1967年）的217人降至民國97年（2008年）約49人。
