Which term could describe a student who frequently skips classes?

The term that describes a student who frequently skips classes is "truant." This word originates from the legal terminology referring to students who are absent from school without permission or valid reason. A 'truant' specifically signifies a pattern of absenteeism that is often habitual and often implies some level of willful neglect of educational responsibilities.

In contrast, "urbane" refers to someone who is sophisticated and cultured, which does not relate to attendance. "Utility" relates to usefulness or practicality, failing to connect with the behavior of skipping classes. "Transcendent" refers to something that goes beyond ordinary limits or is exceptional, which also does not apply to the concept of attending or skipping school. Therefore, "truant" is the most fitting and precise term in this context.
