As in the fourth quarter of 2016, computer and information research scientists, heavy and tractor-trailer truck drivers, and sales engineers remain among the top two hardest-to-fill jobs by sector. New to the list of 170 hardest-to-fill jobs since the last report are audiologists, podiatrists, and electronic home entertainment equipment installers and repairers.

“With the number of job openings in the U.S. reaching record highs, the skills gap continues to be a challenge affecting all sectors of the economy,” said Richard Wahlquist, ASA president and chief executive officer. “For staffing companies, the ASA Skills Gap Index can play an important role in the development of strategies needed to help clients succeed despite growing talent shortages in the workforce.”

The ASA Skills Gap Index was established by the American Staffing Association, using a hiring indicator developed by ASA corporate partner CareerBuilder. The hiring indicator measures the level of difficulty (on a scale of one to 100, with lower scores indicating harder to fill) to fill a specific occupation based on demand, supply of active candidates, and all individuals working in that occupation. The ASA Skills Gap Index concentrates on hiring indicator scores of 50 or less with a demand of more than 2,000 jobs to determine the top hard-to-fill occupations, now based on a one-month snapshot of data. The ASA Skills Gap Index is updated twice a year, after the second and fourth quarters.
