There are approximately 3,200 undergraduates in the College of Engineering, representing all departments. Undergraduate admissions to the College of Engineering is the most selective in the university as a whole. For the 2016-2017 application cycle, the acceptance rate has continued to stay at a low 6.4%, largely a result of increased nonresident interest. The campus as a whole had a 17.5% acceptance rate that year. Applicants apply directly to one of the departments and enter as declared majors within their department. It is also possible to apply as Engineering Undeclared and enter the college; major declaration is required at the end of sophomore year. Once within the college, it is possible to change majors with the approval of Engineering Student Services. It is extremely difficult for undergraduates in other colleges at UC Berkeley to change college into Engineering, as they can only be admitted if a current engineering undergraduate drops. The College of Engineering accepts junior transfer applications for those who have completed at least 60 semester units at another college or university. Preference is given to students at California Community Colleges. Only 9.2% of the over 2,300 junior transfer applicants were admitted for the 2015–16 academic year. Dean Shankar Sastry has stated that the disparity between the college's and the university's acceptance rates is due to the university's failure to respond to the rise in demand for engineering degrees.
