In the most recent release of schools data by DPI, the agency gave the information to the media ahead of time — a practice known as an embargo that gives journalists time to properly digest the data with an agreement not to publish until a certain deadline.
But DPI highlighted all the voucher students’ scores against all the Milwaukee Public Schools’ students scores, instead of separating out the scores of low-income MPS students and comparing only those to the voucher students. That data was not included in the initial release. As a result, it was not included in the stories that the media initially wrote about the results, but was addressed in follow-up stories.
The DPI said the income limit was moot because of a GOP-led law change that allowed more mixed-income children to use vouchers, meaning it was fair to compare all the students in voucher schools to all the children in public schools. Voucher advocates said DPI had an agenda and made their students’ scores appear lower than they would have been against those of only the low-income MPS students.
Other data that can be requested from DPI about voucher schools include: school policies, accreditation status, hours of instruction, the number of applications they have accepted and not accepted, their waiting list numbers, application numbers and payment amounts.
