Yet another study on the effectiveness of charter schools

Phys.org reports:

A first-ever report released July 22 by the University of Arkansas, which ties charter school funding to achievement, finds that public charter schools are more productive than traditional public schools in all 28 states included in analyses of cost-effectiveness and return on investment.

All 28 states!

The national report, titled “The Productivity of Public Charter Schools,” found that charter schools deliver on average an additional 17 points in math and 16 points in reading on the National Assessment of Educational Progress exam taken by students for every $1,000 invested. These differences amount to charter schools being 40 percent more cost-effective in math and 41 percent more cost-effective in reading, compared to traditional public schools.

So when unions (falsely) claim charter schools do better because they get extra funding, remember this study.

The cost-effectiveness analysis of the report found that charter schools in 13 states were found to be more cost-effective in reading because they had higher student achievement results despite receiving less funding than traditional public schools. Charter schools in 11 states were more cost-effective in math for the same reason. The remaining states produced equal or slightly lower achievement with significantly lower funding.

Better results off less funding. Do you get some idea of why the NZ unions are terrified by the trial of charter schools. Think if they produced the same results here!
