Why consider career training alongside college?

Your college major gives you an academic foundation. Short career training can add practical knowledge of a specific job: what the work involves day to day, its vocabulary, common tasks, tools and safety rules. You do not have to wait until graduation: many students take a short course to test a career before choosing a major, to prepare for an internship or a part-time job, or to show employers they understand the work.
