Assumption College (often known as ACK, where the K stands for Kilmore) is an Australian Catholic co-educational secondary day and boarding school.

Assumption College is governed by Marist Schools Australia[2] and is supported by the Catholic Education Commission of Victoria.

[3] Assumption became a member of the Associated Grammar Schools of Victoria (AGSV) in 1958[4] which provides a broad sporting competition for students.

[10] Students may become involved in the cultural life of the College, by performing, by singing, playing a musical instrument, acting, dancing or debating.

However, because many old collegians return to live in rural Victoria and NSW, maintaining a stand-alone team has proven difficult.
