The entire school reform movement is predicated on a
hypothesis: Boosting student achievement, as measured by standardized tests,
will enable greater prosperity, both for individuals and for the country as a
whole. More specifically, improving students’ skills and knowledge in reading,
math, and science will help poor children climb out of poverty, and will assist
all children to prepare for the rigors of college and the workplace. By
building the “human capital” of the American workforce, rising achievement will
also spur economic growth, which will lift all boats.

Call this the Test
Score Hypothesis.

Is stronger academic
performance related to better life outcomes for kids and better economic
outcomes for nations?

It explains reformers’ enthusiasm for test-based
accountability; for “college- and career-ready standards”; for teacher
evaluations based, in significant part, on student outcomes; for “data-based
instruction”; and for much of the rest of the modern-day reform agenda. After
all, if reading, math, and science knowledge and skills are so directly linked
to the life chances of individual kids, and of the livelihood of the country as
a whole, why not get the education system focused like a laser on them?

But is this hypothesis correct? Is stronger academic
performance related to better life outcomes for kids and better economic
outcomes for nations?

In a word: yes. As Kevin Carey noted
recently, the big Chetty et al
didn’t just demonstrate the importance of teacher effectiveness. It
also offered strong support for the Test Score Hypothesis.

you believe standardized tests are worthless or highly flawed or deeply
inadequate or even troublingly limited in accuracy and scope–and many
reasonable people believe these things–then you could dismiss or downplay
value-added measures of teacher effectiveness, by definition….But now the CFR
study says that teachers who are unusually good at helping students score high
on standardized tests today aren’t just unusually good at helping students
score high on standardized tests tomorrow. They also have an unusual effect on
the likelihood of students going to college, going to a good college, earning a
good living, living in a nice place, and saving for retirement. In other words,
whatever the limitations of standardized tests may be, test-based value-added
scores do, in fact, provide valuable information about the things most people
care most about.

Then there’s the international evidence. As Eric Hanushek and
colleagues have been arguing (and
documenting) for years
, there’s a direct link between academic achievement (as
measured by math and science tests) and a country’s economic growth.

level of cognitive skills of a nation’s students has a large effect on its
subsequent economic growth rate. Increasing the average number of years of
schooling attained by the labor force boosts the economy only when increased
levels of school attainment also boost cognitive skills. In other words, it is
not enough simply to spend more time in school; something has to be learned

Hanushek further contends that the only way to solve our country’s
long-term fiscal challenge is to grow our way out of it. If we could indeed
boost the cognitive skills of our students, even by a little, our structural
deficit would go away.

So student achievement
matters a lot. But does it matter the most?

It’s hard to make the case anymore that test scores are
irrelevant. But what remains unknown is whether reading, math, and science are
the most important things that
schools could and should teach.

As Dana Goldstein noted
back in December,

been struck again and again by the newness of the idea that
schooling is primarily a matter of academic achievement…. It is only really since "A Nation at Risk" that we've had a
national dialogue about academic excellence for every child. This is a
much-needed development in American culture, but its discontents are numerous:
A lack of attention paid to the civic, social, and artistic benefits of
schooling, and the ways in which children are (ideally) shaped as moral,
cultured, socially-responsible people by their teachers and school

We might all want schools to walk and chew gum at the same
time—to boost “academic achievement” while also developing “moral, cultured,
socially-responsible people.” But our policies—especially school-level
accountability and test-based teacher evaluations—focus on academic achievement

The nagging question then—the “known unknown”—is whether
other stuff may matter more—both to kids’ life chances and to the country’s
economic success. What if, for instance, “social and emotional
intelligence”—knowing how to relate to others—is more important than many
reformers have been willing to acknowledge? What if these interpersonal skills
are what help lift poor kids out of poverty and enable economies to succeed? Or
other “soft skills” and attributes like grit, perseverance, industriousness,
the ability to delay gratification, and so forth?

In that case, is it smart to push Head Start centers to
focus overwhelmingly on pre-literacy and pre-numeracy skills (as many of us
have)? Is it wise to cut time for recess, to trim extra-curriculars, or to push
for ever-more homework, to be completed by solitary scholars? Does it make
sense to ask teachers to obsess about student achievement over all else?

The private-school sector, which many reformers admire, is
not so conflicted. Every high-end school boasts about its commitment to the “whole child,” to kids’
intellectual, emotional, social, and physical development. These schools would
never consider their graduates to be well educated without an appreciation for
the arts, participation in sports, a commitment to community service, and the
development of strong character. And judging by the admissions policies of the
nation’s great universities, our elite higher education institutions hold this
holistic view, too. Are these non-academic attributes just “extras”—luxuries
that schools serving poor or working-class kids simply cannot afford? Or are
they as essential as academics, for everyone? And, if so, how to instill them?

Reading, math, and science matter a lot, but they are almost
certainly not enough. That is why we must tread gingerly when designing
next-generation school-accountability and teacher-evaluation systems. If we
accidentally create incentives for schools and teachers to focus solely on
academic achievement and ignore the rest, we could be making our children and
our nation less competitive, not more
