Not only are there growing concerns about the supply of apprenticeships meeting demand; there’s a shortage of another important workforce training tool — internships. There were an estimated 5.7 million fewer high-quality internships last year than learners who wanted to intern, according to the Business-Higher Education Forum, or BHEF.Employers last year provided 2.5 million high-quality internships, compared to 8.2 million people who wanted one, the BHEF found. Another million internships that were offered fell short of high standards of quality and skills development, the organization said.
