It should be noted, how-ever, that only about 1 out of every 10 STEM workers has a high school diploma or less. Those with gradu-ate degrees in a STEM job earned more than $40 per hour, nearly $4.50 more per hour on average than those with non-STEM jobs.
Students earning engineering and computer science degrees generally are paid a higher wage rates than students in other disciplines, regardless of class year. Currently, at the bachelorâs degree level for seniors, engineering interns average wages of $20.79 per hour, and computer science/IT interns average $19.10 per hour. These exceed the pay rates for all other intern majors within the senior-class level.
