Even if the average salary of business majors is higher than the average salary of majors in performing arts, performing arts majors get jobs that they will often prefer to the jobs they would get if they were trained in business. We can only list majors that were in the National Survey of College Graduates study. Some majors were excluded because they weren't in the data set. Others were excluded because there were very few people with those majors in the data set. The best alternative is to look around for similar majors.
Some majors are in different colleges at other universities.
Typically you can find your major with a little experimentation. Other majors are offered at CSUN, but under slightly different names. Consult the CSUN course catalog for more information.
