Stanford engineering offers the following majors:
ABET accredited: chemical, civil, mechanical
Not ABET accredited: bio, computer science, electrical, environmental, management science, materials
*ABET accredited until very recently.
Of the non-ABET accredited programs, bioengineering, computer science, and management science are probably the ones where graduates are least likely to seek Professional Engineer licensing. Apparently, Stanford thinks that its electrical, environmental, and material engineering graduates are also unlikely to seek Professional Engineer licensing.
