The College was founded in September 1999 under the name Core Technology Solutions Training Institute and changed its name to Pacific Computer Training Institute in 2002. The Georgia Nonpublic Postsecondary Education Commission (GNPEC) recognized the College as a postsecondary educational institution and authorized it to award certificates and, later, an occupational associate degree.
To reflect the scope and nature of its academic offerings more accurately, the College changed its name to Pacific Institute of Technology (Pacific Tech) in 2009. Since its recognition as an educational institution by GNPEC, the College has awarded hundreds of certificates in Information Technology and other academic programs and, in 2013, graduated its first class of students from its Associate Degree in Information Systems program. In 2019, a certificate program in English as a Second Language was approved by GNPEC and added to the curriculum.
Pacific Tech was accredited by the Accrediting Council for Independent Colleges and Schools (ACICS) in 2014. This status, which must be renewed every four years, was last renewed in 2018.

In June 2020, Pacific Tech obtained authorization from the Student Exchange Visitor Program (SEVP) to issue Form I-20s to international students and enroll nonimmigrant student F-1 visa holders.

In November 2020, Pacific Institute of Technology changed its name to Pacific College of Technology.

In October 2021, PCT was granted Candidate Status for accreditation with the Transnational Association of Christian Colleges and Schools (TRACS).
