David Berliner has designed a provocative thought experiment.
He offers you State A and State B.
He describes salient differences between them.
Can you predict which state has high-performing schools and which state has low-performing schools?

Let’s do a thought experiment. I will slowly parcel out data about two different states. Eventually, when you are nearly 100% certain of your choice, I want you to choose between them by identifying the state in which an average child is likely to be achieving better in school. But you have to be nearly 100% certain that you can make that choice.
To check the accuracy of your choice I will use the National Assessment of Educational Progress (NAEP) as the measure of school achievement. It is considered by experts to be the best indicator we have to determine how children in our nation are doing in reading and mathematics, and both states take this test.
Let’s start. In State A the percent of three and four year old children attending a state associated prekindergarten is 8.8% while in State B the percent is 1.7%. With these data think about where students might be doing better in 4th and 8th grade, the grades NAEP evaluates student progress in all our states. I imagine that most people will hold onto this information about preschool for a while and not yet want to choose one state over the other. A cautious person might rightly say it is too soon to make such a prediction based on a difference of this size, on a variable that has modest, though real effects on later school success.
So let me add more information to consider. In State A the percent of children living in poverty is 14% while in State B the percent is 24%. Got a prediction yet? See a trend? How about this related statistic: In State A the percent of households with food insecurity is 11.4% while in State B the percent is 14.9%. I also can inform you also that in State A the percent of people without health insurance is 3.8% while in State B the percent is 17.7%. Are you getting the picture? Are you ready to pick one state over another in terms of the likelihood that one state has its average student scoring higher on the NAEP achievement tests than the other?
If you still say that this is not enough data to make yourself almost 100% sure of your pick, let me add more to help you. In State A the per capita personal income is $54,687 while in state B the per capita personal income is $35,979. Since per capita personal income in the country is now at about $42,693, we see that state A is considerably above the national average and State B is considerably below the national average. Still not ready to choose a state where kids might be doing better in school?
Alright, if you are still cautious in expressing your opinions, here is some more to think about. In State A the per capita spending on education is $2,764 while in State B the per capita spending on education is $2,095, about 25% less. Enough? Ready to choose now?
Maybe you should also examine some statistics related to the expenditure data, namely, that the pupil/teacher ratio (not the class sizes) in State A is 14.5 to one, while in State B it is 19.8 to one.
As you might now suspect, class size differences also occur in the two states. At the elementary and the secondary level, respectively, the class sizes for State A average 18.7 and 20.6. For State B those class sizes at elementary and secondary are 23.5 and 25.6, respectively. State B, therefore, averages at least 20% higher in the number of students per classroom. Ready now to pick the higher achieving state with near 100% certainty? If not, maybe a little more data will make you as sure as I am of my prediction.
In State A the percent of those who are 25 years of age or older with bachelors degrees is 38.7% while in State B that percent is 26.4%. Furthermore, the two states have just about the same size population. But State A has 370 public libraries and State B has 89.
Let me try to tip the data scales for what I imagine are only a few people who are reluctant to make a prediction. The percent of teachers with Master degrees is 62% in State A and 41.6% in State B. And, the average public school teacher salary in the time period 2010-2012 was $72,000 in State A and $46,358 in State B. Moreover, during the time period from the academic year 1999-2000 to the academic year 2011-2012 the percent change in average teacher salaries in the public schools was +15% in State A. Over that same time period, in State B public school teacher salaries dropped -1.8%.
I will assume by now we almost all have reached the opinion that children in state A are far more likely to perform better on the NAEP tests than will children in State B. Everything we know about the ways we structure the societies we live in, and how those structures affect school achievement, suggests that State A will have higher achieving students. In addition, I will further assume that if you don’t think that State A is more likely to have higher performing students than State B you are a really difficult and very peculiar person. You should seek help!
So, for the majority of us, it should come as no surprise that in the 2013 data set on the 4th grade NAEP mathematics test State A was the highest performing state in the nation (tied with two others). And it had 16 percent of its children scoring at the Advanced level—the highest level of mathematics achievement. State B’s score was behind 32 other states, and it had only 7% of its students scoring at the Advanced level. The two states were even further apart on the 8th grade mathematics test, with State A the highest scoring state in the nation, by far, and with State B lagging behind 35 other states.
Similarly, it now should come as no surprise that State A was number 1 in the nation in the 4th grade reading test, although tied with 2 others. State A also had 14% of its students scoring at the advanced level, the highest rate in the nation. Students in State B scored behind 44 other states and only 5% of its students scored at the Advanced level. The 8th grade reading data was the same: State A walloped State B!
States A and B really exist. State B is my home state of Arizona, which obviously cares not to have its children achieve as well as do those in state A. It’s poor achievement is by design. Proof of that is not hard to find. We just learned that 6000 phone calls reporting child abuse to the state were uninvestigated. Ignored and buried! Such callous disregard for the safety of our children can only occur in an environment that fosters, and then condones a lack of concern for the children of the Arizona, perhaps because they are often poor and often minorities. Arizona, given the data we have, apparently does not choose to take care of its children. The agency with the express directive of insuring the welfare of children may need 350 more investigators of child abuse. But the governor and the majority of our legislature is currently against increased funding for that agency.
State A, where kids do a lot better, is Massachusetts. It is generally a progressive state in politics. To me, Massachusetts, with all its warts, resembles Northern European countries like Sweden, Finland, and Denmark more than it does states like Alabama, Mississippi or Arizona. According to UNESCO data and epidemiological studies it is the progressive societies like those in Northern Europe and Massachusetts that care much better for their children. On average, in comparisons with other wealthy nations, the U. S. turns out not to take good care of its children. With few exceptions, our politicians appear less likely to kiss our babies and more likely to hang out with individuals and corporations that won’t pay the taxes needed to care for our children, thereby insuring that our schools will not function well.
But enough political commentary: Here is the most important part of this thought experiment for those who care about education. Everyone of you who predicted that Massachusetts would out perform Arizona did so without knowing anything about the unions’ roles in the two states, the curriculum used by the schools, the quality of the instruction, the quality of the leadership of the schools, and so forth. You made your prediction about achievement without recourse to any of the variables the anti-public school forces love to shout about –incompetent teachers, a dumbed down curriculum, coddling of students, not enough discipline, not enough homework, and so forth. From a few variables about life in two different states you were able to predict differences in student achievement test scores quite accurately.
I believe it is time for the President, the Secretary of Education, and many in the press to get off the backs of educators and focus their anger on those who will not support societies in which families and children can flourish. Massachusetts still has many problems to face and overcome—but they are nowhere as severe as those in my home state and a dozen other states that will not support programs for neighborhoods, families, and children to thrive.
This little thought experiment also suggests also that a caution for Massachusetts is in order. It seems to me that despite all their bragging about their fine performance on international tests and NAEP tests, it’s not likely that Massachusetts’ teachers, or their curriculum, or their assessments are the basis of their outstanding achievements in reading and mathematics. It is much more likely that Massachusetts is a high performing state because it has chosen to take better care of its citizens than do those of us living in other states. The roots of high achievement on standardized tests is less likely to be found in the classrooms of Massachusetts and more likely to be discovered in its neighborhoods and families, a refection of the prevailing economic health of the community served by the schools of that state.
