An Adjunct Professor is a part-time instructor at a college or university who teaches specific courses but is not a full-time faculty member. They often have other jobs or responsibilities outside of teaching and may be hired for their expertise in a particular field. Adjunct professors typically hold advanced degrees and bring real-world experience to the classroom. Unlike full-time professors, adjuncts usually do not have the same level of job security or benefits. Their contracts are often renewed on a semester-by-semester basis, depending on the institution's needs and budget. Many students appreciate the practical insights that adjunct professors, who may work in industries related to their courses, can provide.
