Assistant Professor

An assistant professor is a beginning-level, tenure-track faculty member at a university or college. Primarily responsible for conducting research, teaching undergraduate and postgraduate courses, and participating in institutional service, they work under probation for a fixed period (typically five to seven years) before being considered for tenure.

Doing CRediT right? Don’t stop at the statement.

A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.

Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.

Core Roles and Responsibilities

The responsibilities of an assistant professor are generally categorised into three main pillars: research, teaching, and service. The research component requires publishing original scholarship in peer-reviewed journals, securing external research grants, and presenting findings at academic conferences. Teaching duties include developing curricula, lecturing, grading, and mentoring students. Service involves participating in departmental committees, reviewing journal submissions, and contributing to the wider community, all of which are essential for showing institutional citizenship.

The Probationary Period and Path to Tenure

Upon appointment, assistant professors enter a probationary period, usually lasting between five and seven years. During this time, their performance is closely monitored and evaluated annually by senior faculty. In the final probationary year, the candidate undergoes a rigorous tenure review process, submitting a portfolio documenting their teaching evaluations, research achievements, and service contributions. Successful candidates are promoted to associate professor and awarded tenure, whilst unsuccessful candidates are usually given a terminal one-year contract to seek employment elsewhere.

Qualifications and Requirements

To secure a position as an assistant professor, candidates must possess a terminal degree relevant to their discipline, such as a Doctor of Philosophy (PhD). In addition to formal qualifications, institutions look for a demonstrated potential for high-quality research, evidence of teaching effectiveness, and postdoctoral experience in scientific fields. Excellent communication skills, a clear research agenda, and the ability to collaborate on interdisciplinary projects are also highly valued during the competitive recruitment process.

Key facts

At a glance

  • It is the entry-level rank on the tenure-track pathway in higher education.
  • Positions are full-time and typically require a terminal degree (e.g., a PhD).

  • Duties are divided into three areas: teaching, research, and institutional service.
  • Failure to secure tenure at the end of the probationary period usually leads to contract termination.

Common misconceptions

What people often get wrong

Often heard: Assistant professors are assistants to full professors.

Actually: Assistant professors are independent faculty members who manage their own research and teach their own classes; the term 'assistant' simply denotes their junior rank within the hierarchy.

Often heard: Tenure is guaranteed after a certain number of years of service.

Actually: Tenure is never guaranteed and is awarded only after a rigorous evaluation of research quality, teaching excellence, and service contributions.

Often heard: Assistant professors focus solely on teaching students.

Actually: Research output is often the most heavily weighted factor in tenure evaluations at research-intensive universities, making scholarly publication vital.
