Good summary. I’ll also add, I’ve seen this happen in Jefferson County, KY (Louisville). Generally speaking, the western half of the county had horrid public schools while the eastern half was much better. In comes school choice and now they’re all

As you stated, this will have a disproportionate impact on the areas surrounding Jxn as a larger metro area in the state. There’s a reason an apartment complex already exists just south of NWR. If you know anyone that teaches there, why don’t you ask them if it makes the school system better. Madison will fall once Queen Mary goes to glory. People will simply continue to sprawl out.
Study the history of Desoto County schools. There’s a reason Desoto Central and now Lewisburg High School exist. It ain’t because the top performers out of Memphis are bringing their superior value system to Southaven High. Like it or not, it’s fact.
The added bonus, aside from wasting more taxpayer dollars on vouchers? People with children very often live where they do simply because of school districts. Once that district goes tits up, my property values face plant. Yet another positive outcome.*
Write it down. Pisgah will be NWR circa 2007 in less than 10 years. A top performing school with a swarm of like-minded individuals (and tax base) to support it. NWR will fall further. Flowood becomes Ridgeland. Old Fannin becomes County Line Road East. Wash. Rinse. Repeat. Perhaps it’s inevitable? This program only fast tracks it. The idea that districts will refuse dollars is ludicrous.
