STI West Negros University has an enrollment of about 10,000 students per semester and produces 1,500 graduates every school year.

The acronym STI is an orphan initialism.

West Negros College (WNC) was founded in 1948 by three Baptist women leaders - Luciana Aritao, Teresa Padilla and Rosario Remitio after the Second World War. They believed that the school would fulfill their dream of Filipinos embracing Christian ideals and tenets. Leodegario Natividad Agustin became the school President in the 1970s; he provided the impetus, despite financial odds, to make West Negros College a successful academic community.

On February 11, 2008, the Commission on Higher Education found West Negros College to be in full compliance of their requirements and granted West Negros College status as a university (WNU).

In April 2013, STI Education Systems Holdings, Inc. announced in a disclosure that they had signed a memorandum of agreement with West Negros University for the acquisition of a controlling interest in the school. The acquisition was done on October 31, 2013.

In 2014, the institution significantly changed its name to STI West Negros University and in 2015, the remaining sole Bacolod campus of STI College in nearby Lacson Street (initially established in 2013) and the West Negros University - Integrated School in Eroreco Subdivision transferred and merged all of its operations to the newly renovated campus in Burgos Street. The school could also be accessed through its backgate at LN Agustin Drive.

As of 2021 to present, aside from the School of Basic Education, Senior High School, and School of Graduate Studies, STI WNU has six Colleges namely, College of Education, Arts and Sciences (CEAS), College of Criminal Justice Education (CCJE), College of Information and Communication Technology (CICT), College of Business Management and Accountancy (CBMA), College of Hospitality and Tourism Management (CHTM), and College of Engineering (COE).
