I have done that now.
I understand the comment about college vouchers was completely misguided... my bad.
I still don't see how they can state there was no "significant overall impact"... but there "was a statistically significant impact" to African American students. This statement fails the logic test... UNLESS 1) African American students were underrepresented... or were only a small fraction of those tracked... OR 2) there was some corresponding DECREASE in college enrollment of non-AA students.
I admit NOT reading the whole study... so perhaps my question / concern is answered therein. (Is it?)
So, overall impact means that they aggregated the results to include ALL races.
Then, they delve past this Huge Average of ALL races by looking at each race/category and to see how they fare.
In other words, if you aggregate ALL the races, there's not much of an impact. If you separate that homogenous blob of ALL races into smaller homogenous blobs (i.e. one category per race), you can see a greater variation.
Makes sense?

Well, from what I read, the SCSF simply filtered out the applicants and gave those who passed a list of schools to attend. How the private schools got on the SCSF list, I don't know. Maybe they met SCSF standards, or maybe it was arbitrary, or maybe the donors of those private schools also donated to the SCSF, so they encouraged the SCSF to bring particular private schools on board. Again, I'm not completely sure on this.

My questions about the study come from comments I hear from anti-voucher people... and I would want to know that that study addressed these. Anti-voucher people will say that...
1) Parents who got their kids involved in this study are clearly MORE ENGAGED than your typical public-school going parent. So the program essentially just grabbed the "cream"... which makes it even harder to teach the rest of the kids.
2) That by participating in the program... the parents were "forced" to be more engaged than they otherwise might have been.... and this sku'd the results.
(2) From what I recall, the study established two groups to control for those kinds of problems. They took one group whose parents immediately encouraged their children to sign up, and another group whose parents kind of floundered (after signing up, or they had their kids use the scholarship money a year later).
So, they separated those who were more committed from those who were less committed.
(1) Yeah, I agree on the first half, but I don't see why placing kids, who are smarter/more capable (within the given formal system of schooling), into clunky stupid schools somehow makes it easier to teach the rest of the kids. If anything, you'd want a more equitable level of kids who are at similar intellectual capacities (however that's measured). For example, it's difficult to teach a class with 10% who are lightyears ahead of the others, but they must be slowed down because 90% of the kids are still on page 1.
jimboston wrote:I don't "buy" these are reasons for NOT having vouchers. Parents and kids who WANT an education and are willing to be more engaged should have the opportunity to get that education. The public schools often make that difficult.
I also like the point about the cost of the Private School tuition being LOWER than the cost of sending the kid to public school.
I have FIRST HAND / PERSONAL knowledge of the waste in large public school systems... so this is NO SURPRISE to me.
Thank you for "forcing" me to educate myself on this study further. If you know the answers to my concerns please advise.... if it's too lengthy an answer (but you know it's contained in the study).. let me know and maybe I will read the whole thing.
Thanks

You're welcome, and what's fun about this study is that it looks promising. Of course, due caution should be exercised in scaling up this program, but at least it shows a proper way to implement vouchers and get positive results. It also illuminates avenues for understanding how to make vouchers more effective for particular categories of kids as well.
