Charter School Performance in New Mexico 2019¶

Charter School Performance in New Mexico. (2019). Center for Research on Education Outcomes, Stanford University. https://credo.stanford.edu/reports/item/charter-school-performance-in-new-mexico-2/

q2 · i? · causal · r2

Quasi-experimental matched comparison using CREDO's Virtual Control Record method on state test growth scores for 2013-14 to 2016-17; the report states the reading and math differences are "statistically insignificant". No effect sizes are printed in the text.

"Because the differences in the growth in both reading and math are statistically insignificant, New Mexico charter students make similar growth in both subjects in the 180-day period as they would have in a traditional school setting."

Related Claims¶

• Charter school students show more annual learning growth in reading and math than matched traditional public school peers — reports the opposite
• New Mexico charter elementary and middle school students show reading surpluses over TPS virtual twins, while high and multi-level charter students grow similarly — related
• Students in New Mexico online charter schools show substantially weaker growth than their TPS virtual twins in both reading and math — reports the opposite
• Urban brick-and-mortar charter students in New Mexico outperform their TPS virtual twins in reading, while suburban, town, and rural charter students are on par — related
• New Mexico charter students' reading advantage emerges in the third year of enrollment, while math growth does not differ by years enrolled — related
• New Mexico charter schools' relative performance improved across CREDO's 2009, 2013, and 2019 studies, though the comparison is only suggestive — related

• Charter school outcomes are mixed as a group, with 17% of charters producing greater academic gains and 37% performing worse than traditional public schools serving similar students — related
• Virtual charter schools show far lower achievement, with students losing the equivalent of half a year of learning in reading and a full year in mathematics — related
