“There are “no measurable differences” between the performance of charter schools and traditional public schools on national reading and math assessments from 2017, a finding that persists when parents’ educational attainment were factored into the results.”

This is the conclusion of a just-released study by the National Center for Education Statistics and reported by EdWeek.

The study reviewed National Assessment of Educational Progress (NAEP) data for 2017 for fourth and eighth grade reading and math scores.

Here are a few conclusions from the new NAEP data comparing charter schools and traditional public schools:

“Based on scores alone, with no controls, there was no statistically significant difference between charters and traditional public schools on NAEP in reading or math.

Why does this matter? Because these schools tend to serve different populations with different background characteristics, which can skew scores.

The researchers controlled for parent educational attainment, and still found no significant difference.

 A lack of data meant NCES couldn’t rule out lots of other factors (like income, teacher quality, race and ethnicity) that are potentially caught up in these test results. The report notes that other factors not controlled for “are substantively correlated with student assessment scores and school type.”

Unfortunately, such info falls on deaf ears in Alabama where charters are now the neatest thing since the hula hoop came along.
