@Setanta,
But steering students
who are still in school toward a GED might be "throwing them toward the wolves" if that credential won't help them get better employment, which is what the research suggests, or if they are so lacking in self discipline and persistence that they won't be able to maintain employment. Employers also want people who can follow rules, show up on time, do their required job, and function in a reliable and predictable manner--and that's what a lot of these kids can't do, which is why they wind up in the in-school GED program. It's not that they lack the intellect, they have other problems that affect their functioning. And they'll continue to have those problems even with their GED--and that's Heckman's point.
It would make more sense to keep these students in a regular diploma track, help them to make up missing credits, and focus on their behavioral/personality/discipline problems--what Heckman refers to as non-cognitive issues--that would really help them in being able to get
and keep a job, or continue with more advanced education and/or job training.
Those who drop out can still have the option of later obtaining a GED, or a regular diploma, perhaps when they are a little more mature or more highly motivated to do so.
I don't see where anyone, including Heckman, is strongly advocating doing away with GED exams
for adults--those over 18--who have already dropped out of school. For those individuals, a GED might help them get a decent job, or a college degree. But it's also a more select and motivated population because these people are choosing to get that credential because they see it as being important to their future, while the same might not be true of the 16 year old who is still in school but has been steered into a GED track because of poor academic performance or behavior problems.
These in-school GED programs may help to keep kids off the streets, and they bring money into school districts, but they might not be adequately preparing these students for the real world of either work or higher education. Alternative schools, which put the focus on really trying to engage these students, and which provide necessary support services, so they possibly can get a regular diploma, or be able to later pass a GED exam, make a lot more sense than these GED programs for 16 and 17 year olds who are still attending school.
