By virtue of the Royal Decree (76/2020), the former Colleges of Technology, the former Colleges of Applied Sciences, and the former Rustaq College of Education were merged under a single umbrella to form a university, thus, the establishment of a branch-based Higher Education Institution (HEI) called the University of Technology and Applied Sciences (UTAS) on August 2020. Such merging is motivated by the Oman Vision 2040 with focus on the National Strategy for Education 2040, Scientific Research Strategy, and the Innovation Strategy, keeping abreast with the modern challenges, priorities, and needs. The UTAS has a population strength of 48,781 students who are registered in the Diploma, Advanced Diploma and Bachelor levels, taking a wide-range of specializations in the fields of Pharmacy, Engineering, Applied Sciences, Business Studies, Information Technology, Photography, Fashion Design, Education, Applied Biotechnology, Engineering, Mass Communication Studies, International Business Administration, Information Technology, and Design. With the increasing number of students, the UTAS has emerged as the largest university in the Sultanate of Oman.

The College of Technology was once having seven (7) branches, It was known as Oman Technical Industrial College, established in 1984 at the initiative of His Majesty Sultan Qaboos bin Said al Said to educate the citizens of Oman by implementing high-quality programs in various fields. There were five other Colleges of Technology established in 1993 except the ones in Shinas and Ibri, which were started in 2005 and 2008, respectively. The COTs was under the Oman’s Ministry of Manpower (now, Ministry of Labor). The College of Applied Sciences was once a group of thirteen public colleges with six campus.
