Because of Saint Louis University's identity as a Jesuit institution, it is well known for its ability to generate intelligent, well-rounded, and social justice-oriented students. All students are required to complete a core curriculum with classes in theology, philosophy, social sciences, mathematics, English, and science. There is also a variety of classes that include a service component, where students are required to get involved in the St. Louis community. SLU is best known for its health science programs, business majors, and degrees in aviation and engineering. No matter what major you choose, your professors will challenge you and try to engage you in the material. Ninety-nine percent of SLU professors have a terminal degree in their field, but in addition to being well-educated and experienced, SLU professors are known for their availability and willingness to help students. Most professors are easily accessible through email, phone, and office hours, where students can come in for extra help. Although there are teaching assistants for large lecture classes and science labs, the curriculum is only taught by the professors.
Class sizes range depending on the subject. The basic sciences, such as biology, chemistry, anatomy, and physiology, are large lecture classes of about 300 students. However, the majority of other classes range between 20 and 30 students. Students tend to complain about the advising system because SLU requires you to meet with an adviser, who frequently seems to be unaware of major requirements, before registering. Luckily, students also meet with faculty mentors in their department who are in the know. The SLU administration has been making efforts to fix the system, and it improves each year.
