School Testers Earn an F

Recently an organization called Colorado School Grades (CSG) set up a website,, inviting parents and others to compare “school performance” based on intensive standardized testing of students mandated under the Bush-Obama “No Child Left Behind” and “Race to the Top” programs. The CSG claims that “information and awareness of school performance leads to better schools for our kids.” Indeed, according to the designers of the massive testing program, its results should be used to reward, punish, or terminate schools based on their performance as measured by the tests.

So what do these results say? The CSG does not make it easy to find out, as they do not present the results, as they really should, in a comprehensive table which can be surveyed as a whole by those interested. Instead, they only reveal data in groups of at most four schools at a time in response to specific inquiries, which makes investigation of the results an exercise somewhat akin to trying to guess the location of enemy ships in the game of “Battleship.” However, based on repeated soundings, there does appear to be a pattern in the data, as may be seen above in representative results of high schools in Jefferson County, a place often viewed as a political and social microcosm of the state.

So, does this testing data, acquired at great expense in money and class time, tell us which schools are doing their job and which are performing poorly? Not at all. Rather, what really jumps out of the data is the extremely strong relationship between school rank and student family income. This correlation is so strong, that as shown in the “predicted rank” column of the table (my own invention, not to be found in the CSG data) it is possible to predict the rank of the school in advance with fair accuracy just by using a simple formula that multiples its percent of low income students by four and subtracts 20.

In short, what we have managed to learn is that the children of doctors and lawyers do better on standardized tests than the children of day laborers and welfare recipients. This raises an interesting question:

Why are we funding this program?

At a time when school funds are scarce, why are we wasting tens of millions of dollars per year in Colorado, and billions nationwide, not to mention close to twenty percent of classroom time, on such testing programs, only to find out nothing that we didn't know before? Does anyone actually believe that affluent suburban Evergreen H.S. students do better than slum neighborhood Jefferson H.S. students because of the superior quality of the school staff? If we switched school staffs, but kept the students in place, would the high scores move with the staffs or stay with the students? The teachers at the lower ranked schools are the front line troops of the melting pot. So, do we punish them because they are willing to take on that tough battle?
