Questions and More Questions on Utah HB215

I'll share with you my questions as I attempt to come up with an opinion on Utah HB215. 

1.) How come only 5,000 students would be funded? Who would be left out? What is the difference between someone who does qualify and someone who doesn't?
2.) Is this the first time home-schoolers would be able to receive vouchers? If parents have three children, and it's $8,000 a shot, wouldn't that mean they receive $24,000 for the year? That would be a substantial portion of the family income.
3.) Students at online academies would also be funded, correct?
4.) Students at charter schools will not be eligible for the scholarships since they are public schools, correct?
5.) In 2007, Utah approved what would have been the most comprehensive voucher program in the nation, but it was rescinded by voters in a referendum. So, Utah does not currently have a voucher program that can reach every child. The two programs we do have (the Carson Smith Scholarship and the Special Needs Opportunity Scholarship) are only for children with special needs, correct?
6.) If a private school were able to get all its students on the proposed Utah Fits All Scholarship Program, wouldn't that supply it with all the funding it needed? It would not need to charge the students, at all. Wouldn't that, in essence (since all the money would be government money), make them public schools (lacking only the accountability for set curriculum, teacher qualifications, and such)?
7.) How would the scholarships adversely affect Utah's public schools in funding per student? If you take students out of the public system, but do not disturb the funding per student, how is that lowering the funding? Is that not what is happening, or am I missing something?
8.) Will taxes have to be increased?
9.) A Trib story notes scores dropped in Louisiana, Ohio and Indiana when students went on voucher progams. Yet, when you google, it says: "The most recent NAEP data shows what other research has found: Private school students score better in almost all subjects. On college entry tests such as the SAT, NAIS found that students in private schools consistently out-performed their public school peers in all subject areas." Why the discrepancy? Or is it just that in some places, private schooling outperforms public, and in other places, public schools outperform private?
Wouldn't a comparison be tilted towards which has more "gifted" students? If private schools have more "gifted" students while public schools have more "slow" students, are comparisons fair?
10.) Why does the bill's sponsor (Rep. Candice Pierucci) oppose studies to see which is more effective, private or public? Originally, her bill specifically prohibited doing any kind of research on that. She then softened that stand, requiring scholarship students to either submit a portfolio of their work or opt in on an assessment. The results of those assessments, however, will not be made public. What would the "assessments" consist of? Would they be the standard tests, the same as given to the public school students? Wouldn't it be reasonable to release the overall performance of all the students -- the average -- while not disclosing the results for any individual student?
