h-index scores between 3 and 5 feel common for assistant professors (lecturers), scores between 8 and 12 fairly standard for creation to the position of tenured associate professor (senior lecturers), and scores between 15 and 20 about right for coming a full professor.
Be apprehensive, still, that these are gross generalisations and factual numbers vary tremendously among disciplines and fields there are. For example, professors in physics and life sciences disciplines have much higher h-index than those in social sciences, computer science, art and design. Numerous full professors, elders and chancellors with veritably low h-index scores, and an exceptional youthful experimenter with an h-index of 10 or 15 might possibly still be working on a post doctorate.
