Class sizes at the University of Alaska—Fairbanks are small "even [at] the 100-level." The professors "not only have book smarts but real-life experience in their fields." In general they "invite comment, make sure there is time for discussion, change the direction of the class based on student interest and make themselves available to help." In addition to small class sizes students here benefit from faculty who "are very excited about their subject matter," which "makes for a great learning environment." They "are extremely accessible and supportive" and "will go out of there way to make sure you know the material and you will pass the course." Although there are reports of "some average professors," with regards to the "upper-level and major-specific classes," overall professors here are "academically stimulating and an excellent resource." It has been noted that, in the field of petroleum engineering specifically, "it seems as though [the professors] focus more on the theoretical side of things instead of the practical side."
