A century ago, often under pressure from labor unions, states passed seat-time and mandatory-attendance laws that compelled youngsters to stay in school, and out of the competition for jobs. The laws haven't changed much today, but kids have, and by their midteens, many of them--bored with high school or academically beyond it--are ready for the next step. The states' almost uniform response has been dual-enrollment programs. Kids remain in high school but are able to take college courses at the same time. Almost every state has some sort of dual-enrollment policy, and 12 states require their school districts and public postsecondary schools to work out dual-enrollment partnerships, according to the Education Commission of the States (ECS). Today, as legislators see it, dual enrollment offers something for everyone: academic enrichment for kids who have maxed out the honors and accelerated classes their schools offer; a glimpse of college rigor for high school laggards; and a leg up on a career for those who enroll in trade programs. Not incidentally, dual enrollment promises to speed youngsters through college and into the workforce, cutting college costs for parents and taxpayers alike. Dual-enrollment policies and participation patterns vary widely across states, and programs designed explicitly for advanced students are a small fraction of the total. Most dual enrollment courses are taught in high school classrooms by high school teachers who have received some training and certification by their university or community-college partner and follow its curriculum. Others are online or are televised into high school classrooms.
