A teacher who is hired on a part-time, contractual basis, and does not have a proper working period or tenure is referred to as a guest teacher. They do not hold the responsibilities of a full-time teacher but do teach like full-time teachers. They can also be called Guest teacher.

Guest teacher are not required to hold or attend meetings, and conduct research for the development of the school. They are exempted from most of the responsibilities of a full-time teacher. They hold prominent positions elsewhere but are required to spend time with students to fulfill their teaching responsibility. Regardless, they should have ample enough teaching skills. They play an equal role in imparting quality education to the students and their role cannot be sidelined.

They teach various subjects of the school and introductory subjects and are hired on a semester basis. In addition, guest teacher, at some places, are required to possess a highly technical professional training.  It depends on the level of education they are imparting. 

Some community schools and vocational education schools hire guest teachers with good work experience in the teaching field. The limited-term faculty is expected to teach like full-time faculty. The salaries of the adjunct teachers  are a bit low when compared to the full-time, and the roles and responsibilities of a guest teacher are also less in comparison.
