Teachers make up a vital component to any society, prompting the 'Teaching in Higher Education' infograph to take a look at American post-secondary teachers by the numbers. You may be surprised to learn that the sectors of teaching in the areas of health and vocational training far surpass any other sector. The sciences -- bio and computer in particular -- are falling behind with the number of teachers in their area.
One of the main differences that sets apart part-time and full-time professors at post-secondary education schools is their level of education. While part-time profs are found to be more likely to have a master's as their highest level, full-time profs are considerably more likely to have a PhD as theirs.
