In 1973, the first computer science faculty member joined the Department of Mathematics to teach and develop programs in computer science; and by 1974, both the bachelor of science and the bachelor of arts degrees in computer science were offered by the Department of Mathematics.

During the 1978-79 academic year, the University approved the formation of the Institute of Engineering Science to offer an engineering degree within the College of Arts and Sciences. The Institute became operational with its first director in the fall of 1979. Prior to the formation of the Institute, students could participate in a joint (or cooperative) program with selected schools of engineering which could lead to a BA from Baylor and a BS from the selected engineering school.

In June 1980, the Computer Science program in the Department of Mathematics was combined with the Engineering Science program in the Institute of Engineering Science to form the Department of Engineering and Computer Science. The Department grew rapidly and in February 1982, the Baylor Computer Science program gained national recognition by winning the International Scholastic Programming Contest.

In 1985, the master of science degree in computer science was offered for the first time at Baylor and, in that same year, the Baylor bachelor of science degree in Computer Science was one of only 50 programs to be accredited by the Computer Science Accreditation Commission, Inc. (CSAC) of the Computer Science Accreditation Board (CSAB), the national accrediting agency for computer science programs.

In the Summer of 1988, the Department of Engineering and Computer Science moved into the newly constructed Rogers Engineering and Computer Science Building, which was built specifically to support the engineering and computer science programs. In 1989, the Baylor Engineering Program was accredited by the Engineering Accreditation Commission (EAC) of the Accreditation Board for Engineering and Technology (ABET), the national accrediting agency for engineering programs.*

The present organization was established in 1995, with the formation of the School of Engineering and Computer Science and its two departments, the Department of Computer Science and the Department of Engineering.

In 2000-2001, the Department of Engineering requested and EAC/ABET granted separate accreditation of the department's three baccalaureate majors: Electrical and Computer Engineering, Mechanical Engineering, and Engineering.

The School of Engineering and Computer Science partnered with Campus Living & Learning in 2003 on the University's first residential village, the Engineering & Computer Science Living-Learning Center (ECS-LLC).

The Baylor University Board of Regents approved a new master's program in 2004, giving the School its first graduate programs in engineering.

The Department of Mechanical Engineering was established in the Fall of 2006. Today, the School of Engineering & Computer Science consists of three academic departments.
