Education Levels of Current Workers
The Bureau of Labor Statistics lists a bachelor's degree as the typical education needed to enter this occupation. The chart below shows the highest level of education held by people already working in this field, ages 25 and older. It includes workers who earned more education than the job requires and workers who entered the field under earlier requirements, so the largest bar is not the entry requirement. For example, if someone finished a master's degree and then started working in this field, they are counted under “Master's degree” here, but the job itself typically asks for a bachelor's degree.
