Forty one years later, the Faculty of Science has expanded to its present student enrollment of 3489 undergraduates, about 413 graduate students, and a staff of 121 members.

When it was first established, Faculty of Science comprised four departments: Mathematics, Physics and Materials Sciences, Chemistry and Biological Sciences. In 1973, the Department of Geology was added followed by the Department of Computer Science in 1982. Due to an ever-pressing demand for graduates in Computer Science, the department was expanded in 2000 to form the nucleus of the King Abdullah II School for Information Technology. In 2002, the Mathematics department added an Actuarial Science program, and in 2004 the Biological Sciences added a new program of Medical Analysis.
