Over the next few weeks, The Brian Lehrer Show will offer a series of conversations with and about people who've earned "skills through alternative routes"—including community college, micro-credentialing programs and on-the-job training—and successful livings without a four-year college degree. Today, Audrey Mickahail, senior vice president at Opportunity@Work, a nonprofit working to expand access to career opportunities, and Aaliyah Siddiqi, marketing operations specialist for a Philadelphia pharmaceutical company, talk about alternative routes to professional careers.
