Academic Titles at US Colleges
    Not everyone who teaches in a college or university is a professor. Many are instructors or lecturers. In fact, not even all professors are full professors. Many of them are assistant or associate professors oi adjunct professors.
    So what do all of these different academic titles mean at American colleges and universities? Get ready for a short lecture, especially if you are thinking of a career in higher education.
[1]Professors usually need a doctoral degree. But sometimes a school will offer positions to people who have not yet received their doctorate. This person would be called an instructor until the degree has been completed. After that, the instructor could become an assistant professor. Assistant professors do not have tenure.
    [2]Tenure means a permanent appointment This goal of greater job security is harder to reach these days. Fewer teaching positions offer the chance for tenure. [3]A professor with tenure cannot be easily dismissed. Such appointments are permanent Those hired with the understanding they will seek tenure are said to be "on the tenure track." [4]Assistant professor is the first job on this path. [5]Assistant professors generally have five to seven years to gain tenure. During this time, other faculty members study the person’s work. [6]If tenure is denied, then the assistant professor usually has a year to find another job. Candidates for tenure may feel great pressure to get research published. "Publish or perish" is the traditional saying. [7]An assistant professor who receives tenure becomes an associate professor. An associate professor may later be appointed a full professor. Assistant, associate and full professors perform many duties. They teach classes. They advise students. And they carry out research. They also serve on committees and take part in other community activities.
    Other faculty members are not expected to do all these jobs. They are not on a tenure track. Instead, they might be in adjunct or visiting positions. [8]An adjunct professor is hired to teach for a limited time, usually one semester. Adjunct professors may have a doctorate. [9]But they receive lower pay than those on the tenure track and have no job security. The American Association of University Professors says sixty-eight percent of all teacher appointments at American colleges today are adjuncts. [10]College officials say one reason is low budgets. Another is having the freedom to change teachers as courses become more
or less popular. They also say part-time adjuncts can provide real world experience for their students. But the AAUP and other college officials say too many adjuncts mean lower educational quality. They say adjuncts do not have the time or support to help students outside class. And they say fewer tenure track positions mean fewer people to work with students, create new courses and serve on committees.
    A visiting professor has a job at one school but works at another for a period of time. Another position is that of lecturer. Lecturers teach classes, but they may or may not have a doctorate.
