Hanushek recently did a back-of-the-envelope calculation about what even a rudimentary focus on teacher quality could mean for the United States. If you rank the countries of the world in terms of the academic performance of their schoolchildren, the United States is just below average, half a standard deviation below a clump of relatively high-performing countries like Canada and Belgium. According to Hanushek, the United States could close that gap simply by replacing the bottom 6 percent to 10 percent of public-school teachers with teachers of average quality. After years of worrying about issues like school funding levels, class size, and curriculum design, many reformers have come to the conclusion that nothing matters more than finding people with the potential to be great teachers. But there’s a hitch: no one knows what a person with the potential to be a great teacher looks like. The school system has a quarterback problem.

Kickoff time for Missouri’s game against Oklahoma State was seven o’clock. It was a perfect evening for football: cloudless skies and a light fall breeze. For hours, fans had been tailgating in the parking lots around the stadium. Cars lined the roads leading to the university, many with fuzzy yellow-and-black Tiger tails hanging from their trunks. It was one of Mizzou’s biggest games in years. The Tigers were undefeated and had a chance to become the No. 1 college football team in the country. Shonka made his way through the milling crowds and took a seat in the press box. Below him, the players on the field looked like pieces on a chessboard.
The Tigers held the ball first. Chase Daniel stood a good seven yards behind his offensive line. He had five receivers, two to his left and three to his right, spaced from one side of the field to the other. His linemen were widely spaced as well. In play after play, Daniel caught the snap from his center, planted his feet, and threw the ball in quick seven- and eight-yard diagonal passes to one of his five receivers.
The style of offense that the Tigers run is called the spread, and most of the top quarterbacks in college football — the players who will be drafted into the pros — are spread quarterbacks. By spacing out the offensive linemen and wide receivers, the system makes it easy for the quarterback to figure out the intentions of the opposing defense before the ball is snapped: he can look up and down the line, “read” the defense, and decide where to throw the ball before anyone has moved a muscle. Daniel had been playing in the spread since high school; he was its master. “Look how quickly he gets the ball out,” Shonka said. “You can hardly go a thousand and one, a thousand and two, and it’s out of his hand. He knows right where he’s going. When everyone is spread out like that, the defense can’t disguise its coverage. Chase knows right away what they are going to do. The system simplifies the quarterback’s decisions.”
But for Shonka this didn’t help matters. It had always been hard to predict how a college quarterback would fare in the pros. The professional game was, simply, faster and more complicated. With the advent of the spread, though, the correspondence between the two levels of play had broken down almost entirely. NFL teams don’t run the spread. They can’t. The defenders in the pros are so much faster than their college counterparts that they would shoot through those big gaps in the offensive line and flatten the quarterback. In the NFL, the offensive line is bunched closely together. Daniel wouldn’t have five receivers. Most of the time, he’d have just three or four. He wouldn’t have the luxury of standing seven yards behind the center, planting his feet, and knowing instantly where to throw. He’d have to crouch right behind the center, take the snap directly, and run backward before planting his feet to throw. The onrushing defenders wouldn’t be seven yards away. They would be all around him, from the start. The defense would no longer have to show its hand, because the field would not be so spread out. It could now disguise its intentions. Daniel wouldn’t be able to read the defense before the snap was taken. He’d have to read it in the seconds after the play began.
“In the spread, you see a lot of guys wide open,” Shonka said. “But when a guy like Chase goes to the NFL, he’s never going to see his receivers that open — only in some rare case, like someone slips or there’s a bust in the coverage. When that ball’s leaving your hands in the pros, if you don’t use your eyes to move the defender a little bit, they’ll break on the ball and intercept it. The athletic ability that they’re playing against in the league is unbelievable.”
As Shonka talked, Daniel was moving his team down the field. But he was almost always throwing those quick, diagonal passes. In the NFL, he would have to do much more than that — he would have to throw long, vertical passes over the top of the defense. Could he make that kind of throw? Shonka didn’t know. There was also the matter of his height. Six feet was fine in a spread system, where the big gaps in the offensive line gave Daniel plenty of opportunity to throw the ball and see downfield. But in the NFL, there wouldn’t be gaps, and the linemen rushing at him would be six five, not six one.
“I wonder,” Shonka went on. “Can he see? Can he be productive in a new kind of offense? How will he handle that? I’d like to see him set up quickly from center. I’d like to see his ability to read coverages that are not in the spread. I’d like to see him in the pocket. I’d like to see him move his feet. I’d like to see him do a deep dig, or deep comeback. You know, like a throw twenty to twenty-five yards down the field.”
It was clear that Shonka didn’t feel the same hesitancy in evaluating the other Mizzou stars — the safety Moore, the receivers Maclin and Coffman. The game that they would play in the pros would also be different from the game they were playing in college, but the difference was merely one of degree. They had succeeded at Missouri because they were strong and fast and skilled, and these traits translate in kind to professional football.
A college quarterback joining the NFL, by contrast, has to learn to play an entirely new game. Shonka began to talk about Tim Couch, the quarterback taken first in that legendary draft of 1999. Couch set every record imaginable in his years at the University of Kentucky. “They used to put five garbage cans on the field,” Shonka recalled, shaking his head, “and Couch would stand there and throw and just drop the ball into every one.” But Couch was a flop in the pros. It wasn’t that professional quarterbacks didn’t need to be accurate. It was that the kind of accuracy required to do the job well could be measured only in a real NFL game.
Similarly, all quarterbacks drafted into the pros are required to take an IQ test — the Wonderlic Personnel Test. The theory behind the test is that the pro game is so much more cognitively demanding than the college game that high intelligence should be a good predictor of success. But when the economists David Berri and Rob Simmons analyzed the scores — which are routinely leaked to the press — they found that Wonderlic scores are all but useless as predictors. Of the five quarterbacks taken in round one of the 1999 draft, Donovan McNabb, the only one of the five with a shot at the Hall of Fame, had the lowest Wonderlic score. And who else had IQ scores in the same range as McNabb? Dan Marino and Terry Bradshaw, two of the greatest quarterbacks ever to play the game.
We’re used to dealing with prediction problems by going back and looking for better predictors. We now realize that being a good doctor requires the ability to communicate, listen, and empathize — and so there is increasing pressure on medical schools to pay attention to interpersonal skills as well as to test scores. We can have better physicians if we’re just smarter about how we choose medical school students. But no one is saying that Dan Shonka is somehow missing some key ingredient in his analysis; that if he were only more perceptive he could predict Chase Daniel’s career trajectory. The problem with picking quarterbacks is that Chase Daniel’s performance can’t be predicted. The job he’s being groomed for is so particular and specialized that there is no way to know who will succeed at it and who won’t. In fact, Berri and Simmons found no connection between where a quarterback was taken in the draft — that is, how highly he was rated on the basis of his college performance — and how well
he played in the pros.
The entire time that Chase Daniel was on the field against Oklahoma State, his backup, Chase Patton, stood on the sidelines, watching. Patton didn’t play a single down. In his four years at Missouri, up to that point, he had thrown a total of twenty-six passes. And yet there were people in Shonka’s world who thought that Patton would end up as a better professional quarterback than Daniel. The week of the Oklahoma State game, the national sports magazine ESPN even put the two players on its cover, with the title “CHASE DANIEL MIGHT WIN THE HEISMAN” — referring to the trophy given to college football’s best player. “HIS BACKUP COULD WIN THE SUPER BOWL.” Why did everyone like Patton so much? It wasn’t clear. Maybe he looked good in practice. Maybe it was because this season in the NFL a quarterback who had also never started in a single college game is playing superbly for the New England Patriots. It sounds absurd to put an athlete on the cover of a magazine for no particular reason. But perhaps that’s just the quarterback problem taken to an extreme. If college performance doesn’t tell us anything, why shouldn’t we value someone who hasn’t had the chance to play as highly as we do someone who plays as well as anyone in the land?

Picture a young preschool teacher, sitting on a classroom floor surrounded by seven children. She is holding an alphabet book, and working through the letters with the children, one by one: “A is for apple.…C is for cow.” The session was taped, and the videotape is being watched by a group of experts, who are charting and grading each of the teacher’s moves.
After thirty seconds, the leader of the group — Bob Pianta, the dean of the University of Virginia’s Curry School of Education — stops the tape. He points to two little girls on the right side of the circle. They are unusually active, leaning into the circle and reaching out to touch the book.
“What I’m struck by is how lively the affect is in this room,” Pianta said. “One of the things the teacher is doing is creating a holding space for that. And what distinguishes her from other teachers is that she flexibly allows the kids to move and point to the book. She’s not rigidly forcing the kids to sit back.”
Pianta’s team has developed a system for evaluating various competencies relating to student-teacher interaction. Among them is “regard for student perspective”; that is, a teacher’s knack for allowing students some flexibility in how they become engaged in the classroom. Pianta stopped and rewound the tape twice, until what the teacher had managed to achieve became plain: the children were active, but somehow the class hadn’t become a free-for-all.
“A lesser teacher would have responded to the kids’ leaning over as misbehavior,” Pianta went on. “ ‘We can’t do this right now. You need to be sitting still.’ She would have turned this off.”
Bridget Hamre, one of Pianta’s colleagues, chimed in: “These are three- and four-year-olds. At this age, when kids show their engagement it’s not like the way we show our engagement, where we look alert. They’re leaning forward and wriggling. That’s their way of doing it. And a good teacher doesn’t interpret that as bad behavior. You can see how hard it is to teach new teachers this idea, because the minute you teach them to have regard for the student’s perspective, they think you have to give up control of the classroom.”
The lesson continued. Pianta pointed out how the teacher managed to personalize the material. “C is for cow” turned into a short discussion of which of the kids had ever visited a farm. “Almost every time a child says something, she responds to it, which is what we describe as teacher sensitivity,” Hamre said.
The teacher then asked the children if anyone’s name began with that letter. “Calvin,” a boy named Calvin says. The teacher nods, and says, “Calvin starts with C.” A little girl in the middle says, “Me!” The teacher turns to her. “Your name’s Venisha. Letter V. Venisha.”
It was a key moment. Of all the teacher elements analyzed by the Virginia group, feedback — a direct, personal response by a teacher to a specific statement by a student — seems to be most closely linked to academic success. Not only did the teacher catch the “Me!” amid the wiggling and tumult; she addressed it directly.
“Mind you, that’s not great feedback,” Hamre said. “High-quality feedback is where there is a back-and-forth exchange to get a deeper understanding.” The perfect way to handle that moment would have been for the teacher to pause and pull out Venisha’s name card, point to the letter V, show her how different it is from C, and make the class sound out both letters. But the teacher didn’t do that — either because it didn’t occur to her or because she was distracted by the wiggling of the girls to her right.
“On the other hand, she could have completely ignored the girl, which happens a lot,” Hamre went on. “The other thing that happens a lot is the teacher will just say, ‘You’re wrong.’ Yes-no feedback is probably the predominant kind of feedback, which provides almost no information for the kid in terms of learning.”
Pianta showed another tape, of a nearly identical situation: a circle of preschoolers around a teacher. The lesson was about how we can tell when someone is happy or sad. The teacher began by acting out a short conversation between two hand puppets, Henrietta and Twiggle: Twiggle is sad until Henrietta shares some watermelon with him.
“The idea that the teacher is trying to get across is that you can tell by looking at somebody’s face how they’re feeling, whether they’re feeling sad or happy,” Hamre said. “What kids of this age tend to say is you can tell how they’re feeling because of something that happened to them. They lost their puppy and that’s why they’re sad. They don’t really get this idea. So she’s been challenged, and she’s struggling.”
The teacher begins, “Remember when we did something and we drew our face?” She touches her face, pointing out her eyes and mouth. “When somebody is happy, their face tells us that they’re happy. And their eyes tell us.” The children look on blankly. The teacher plunges on: “Watch, watch.” She smiles broadly. “This is happy! How can you tell that I’m happy? Look at my face. Tell me what changes about my face when I’m happy. No, no, look at my face.…No. . . .”
A little girl next to her says, “Eyes,” providing the teacher with an opportunity to use one of her students to draw the lesson out. But the teacher doesn’t hear her. Again, she asks, “What’s changed about my face?” She smiles and she frowns, as if she can reach the children by sheer force of repetition. Pianta stopped the tape. One problem, he pointed out, was that Henrietta made Twiggle happy by sharing watermelon with him, which doesn’t illustrate what the lesson is about.
“You know, a better way to handle this would be to anchor something around the kids,” Pianta said. “She should ask, ‘What makes you feel happy?’ The kids could answer. Then she could say, ‘Show me your face when you have that feeling. OK, what does So-and-So’s face look like? Now tell me what makes you sad. Show me your face when you’re sad. Oh, look, her face changed!’ You’ve basically made the point. And then you could have the kids practice, or something. But this is going to go nowhere.”
“What’s changed about my face?” the teacher repeated, for what seemed like the hundredth time. One boy leaned forward into the circle, trying to engage himself in the lesson, in the way that little children do. His eyes were on the teacher. “Sit up!” she snapped at him.
As Pianta played one tape after another, the patterns started to become clear. Here was a teacher who read out sentences in a spelling test, and every sentence came from her own life — “I went to a wedding last week” — which meant she was missing an opportunity to say something that engaged her students. Another teacher walked over to a computer to do a PowerPoint presentation, only to realize that she hadn’t turned it on. As she waited for it to boot up, the classroom slid into chaos.
Then there was the superstar — a young high-school math teacher in jeans and a green polo shirt. “So let’s see,” he began, standing up at the blackboard. “Special right triangles. We’re going to do pr
actice with this, just throwing out ideas.” He drew two triangles. “Label the length of the side, if you can. If you can’t, we’ll all do it.” He was talking and moving quickly, which Pianta said might be interpreted as a bad thing, because this was trigonometry. It wasn’t easy material. But his energy seemed to infect the class. And all the time he offered the promise of help. If you can’t, we’ll all do it. In a corner of the room was a student named Ben, who’d evidently missed a few classes. “See what you can remember, Ben,” the teacher said. Ben was lost. The teacher quickly went to his side: “I’m going to give you a way to get to it.” He made a quick suggestion: “How about that?” Ben went back to work. The teacher slipped over to the student next to Ben, and glanced at her work. “That’s all right!” He went to a third student, then a fourth. Two and a half minutes into the lesson — the length of time it took that subpar teacher to turn on the computer — he had already laid out the problem, checked in with nearly every student in the class, and was back at the blackboard, to take the lesson a step further.
“In a group like this, the standard MO would be: he’s at the board, broadcasting to the kids, and has no idea who knows what he’s doing and who doesn’t know,” Pianta said. “But he’s giving individualized feedback. He’s off the charts on feedback.” Pianta and his team watched in awe.

Educational-reform efforts typically start with a push for higher standards for teachers — that is, for the academic and cognitive requirements for entering the profession to be as stiff as possible. But after you’ve watched Pianta’s tapes and seen how complex the elements of effective teaching are, this emphasis on book smarts suddenly seems peculiar. The preschool teacher with the alphabet book was sensitive to her students’ needs and knew how to let the two girls on the right wiggle and squirm without disrupting the rest of the students; the trigonometry teacher knew how to complete a circuit of his classroom in two and a half minutes and make everyone feel that he or she was getting his personal attention. But these aren’t cognitive skills.
