Since the beginning of the Covid-19 pandemic, America's parents have shifted nearly 2 million students from public schools to alternatives that include private schools and home schooling. For public schools, that represents a loss of about 4% of their enrollment.

Expect the exodus to grow larger, as the United States is undergoing a major change in philosophy regarding publicly-funded K-12 education, away from funding government-run school systems and toward funding individual students—with parents getting to choose where their children learn.

In June, Arizona put itself at the leading edge of that shift: Every Arizona family can now direct about $7,000 a year per student toward the education solution of their choice. Funds can be used for private schools, home schooling, tutoring and online learning.
