And in finland there is school choice, which means that the money follows the student. If no students choose to go to school X, the school gets shut down. This is quite similar to what the charters in the US represent.
> These aspects from the article sound like US charter schools.
Some charter schools. A minority. Others are run like tiny military academies, or have gone all-in on high-stakes testing, or profit by relying on low-paid short-term teachers with high turnover, or are mainly financial schemes/scams with schools attached (cf. the alternet link a few posts upthread).
All of the bits you listed actually sound precisely like my southern California suburban public elementary school experience in the mid–late 1990s. Unfortunately the school got constant pushback from the school district and state for not being excited enough about letter grades or standardized tests, but was able to mostly persist its culture through support from local parents.
