Tuscon versus Columbus: Round Two

February 16, 2018

(Guest Post by Matthew Ladner)

Yesterday I presented statewide NAEP information contrasting urban schooling achievement trends in Arizona and Ohio, and specifically in Tucson and Columbus. Columbus is surrounded by suburban districts choosing not to participate in open enrollment (typical I fear) while Tucson is surrounded by suburban districts who do participate in open enrollment-and actively so.

Today I remembered the cool data tool that the NYT developed using Sean F. Reardon’s data.

Let me start by saying that if I had to pick a district to showcase Arizona, it would not be Tucson. While I am fully aware of some outstanding schools in TUSD, the district’s reputation (fairly or not-I am no authority on the subject) usually involves enrollment decline, empty school buildings, union sway in school board elections and controversy over some sort of voluntary “La Raza” curriculum in the high schools. A decade ago you could peer into the state’s AIMS data and watch student cohorts fall further behind as they “progressed” through the system.

Arizona however has been leading the nation in academic gains, and Tucson continues to face steady and considerable competition for students not only from charter schools and private choice programs, but also from nearby suburban districts. It is my contention that this broad competition enables the bottom up accountability that results in Arizona’s average charter school closing after only 4 years despite receiving 15 year charters from the state. Reardon’s data includes both district and charter school trends, but how did Tucson fare between 2010 (3rd grade scores) and 2015 (8th grade scores) in terms of academic growth?

Tucson Unified (and charters operating within district boundaries) scored at the 64th percentile for growth during this period. Columbus Ohio meanwhile also had a charter school law active, but no suburban districts willing to allow transfers, per the Fordham map:

How did Columbus fare in the Reardon data?

Columbus scored in the 22nd percentile in academic growth during this period. The news is also grim in Cleveland, Toledo and Dayton although Cincinnati stands out as the Ohio urban progress champion during this period. Overall however things look like in NAEP for the two states.

Now if you want to see something really cool:

The east-west on these columns indicate the relative wealth of the district, and Phoenix Elementary and charters sit at the tip of the gains spear.
