The Fern Hill Parent Teacher Association was established in 1911 as a branch of the National Congress of Mothers. It backed projects such as upgrading the school water fountain and remodeling the school when the original structure was deemed "unsanitary." The PTA also voted on the measure of splitting up Fern Hill's school population into elementary and intermediate. Fern Hill was the only school within Tacoma Public Schools to have grades from kindergarten to eighth in one building. The PTA also helped to plant a tree celebrating the 100th anniversary of Tacoma Public Schools on Fern Hill property.
