This is just incorrect. My kids go to a charter school that is public (CA), but has a lottery. The school is approx 50% latino. The kids with the most problems do not have Parents Active enough in their kids lives (likely do to Dual-incomes and very busy parents). There are various other reasons; English as 2nd language, too much screen time, unbridled web activity, lack of appropriate kid boundaries, grammy fell asleep and didn't watch the kids, etc.

The school does not kick out the low performers.

The education board has lowered the standard for testing criteria.

Thanks to the State gov.
