Charter schools were created to help the neediest students. Now, however, many charters skim off the most advantaged students and avoid those who are needy. This harms the public schools, removing their best students and overloading them with the students who require the most services.

It doesn’t get any clearer than this:

“Woodland Community Consolidated School District 50 in Gurnee filed a lawsuit against Prairie Crossing Charter School and two state agencies Tuesday, alleging that millions in state aid that should have been spent on instruction for low-income and at-risk students have been “siphoned away” to pay for a small number of charter school students, officials announced.”

“The district has asked a Cook County court to reverse a five-year reauthorization of Prairie Crossing Charter School approved in April by the Illinois State Charter School Commission, which is named in the lawsuit. The district also named as a defendant the Illinois State Board of Education, which authorized the charter school’s creation in 1999.”

“Woodland officials allege in the lawsuit that state funds intended for low-income or limited-English-proficient learners are mostly going toward the education of 321 charter school pupils, the majority of whom are “high-achieving Caucasian and Asian middle-class students,” Vondracek said.

“About 31 percent – or 1,997 — of the Woodland school district’s 6,425 students are considered “at risk,” compared with fewer than 2 percent of the charter school students, he said. Yet most of the $3.5 million in state aid that the District 50 was eligible to receive during fiscal 2012-13 went to the charter school, officials said.

Since 1999, the charter school has taken $30 million from the district’s budget.

The charter’s avoidance of high- needs students is blatantly unfair.
