It was established in 1948 by the Free Wesleyan Church of Tonga,[2] being split away from Tupou College.
[3] The College is a member of the South Pacific Association of Theological Schools,[4] and offers a Bachelor of Divinity programme accredited by the same.
The site is of historical and cultural significance to the Tongans as it was once the domain of the famed Tu'i Ha'amea, Lo'au, who devised the royal drinking ceremony, the Taumafa Kava.
Prior to the establishment of Sia'atoutai, theological training was undertaken at Tupou College, where the principal, the Reverend A. Harold Wood, fulfilled the dual roles of secondary school executive and tertiary educator (with theological classes conducted in the evening, when the school day had ended).
