Way back in 2014, Secretary of Education Arne Duncan was selling the idea that teachers should be rewarded or punished based on their students’ test scores. That idea, baked into Race to the Top, was a dismal failure. Teachers who taught the neediest kids got low ratings, and teachers in the most advantaged schools got the highest ratings. Bill Gates was similarly infatuated with the idea, and he handed out hundreds of millions of dollars to districts and charter chains to test it. Rigorous evaluation showed it to be demoralizing to teachers with no impact on test scores.

What we should have learned from the experience of Race to the Top is that carrots and sticks applied to teachers do not help students and do not improve education.

It’s parents and home life that have the largest effect on student learning. So said the American Statistical Association in 2014, making a futile attempt to persuade Secretary Duncan that he was on the wrong track.

Susan E. Mayer and Ariel Kalil explain why policymakers should focus on parents and help them become better parents. [Let me add, however, that I disagree with their comments about reading and math proficiency. As I have written many times before, NAEP proficiency is not grade level; it is a high bar, and it’s unlikely that most students would ever score the equivalent of an A.]

They write:

American schoolchildren are performing abysmally in tests of basic skills. Only 36% of fourth-grade students were deemed proficient in national math tests and only 33% were deemed proficient in reading as of 2022, the latest year for which such data is available.

Those numbers are even worse than before the pandemic – 5 percentage points lower in math from 2019 and 2 percentage points lower in reading. And the drop in reading and math proficiency after the pandemic has happened to both economically advantaged and disadvantaged children. Students across the board need help.

There is a tendency to blame schools – and by extension, teachers – for students’ poor performance. The temptation to focus solely on schools, however, is misguided. Parents are the ones who must build the foundation for children’s learning. Yet parenting has long been viewed as a private behavior for which women are presumed to possess unique instincts, leaving parents with little evidence-based guidance on how to develop their children’s skills.

Meanwhile, the political right often favors more accountability for teachers, more charter schools and more vouchers for private schools. The political left often favors more teacher training, reducing class sizes, more equitable distribution of school resources and patience as students recover from the pandemic-related dip in scores.

But it’s parents and family background that make the biggest difference. This is evident because the gap in children’s math and reading test scores is already large at the start of kindergarten, in line with their socioeconomic status, and does not narrow as children progress through schooling.

Many people think that the solution, therefore, is to improve parents’ socioeconomic status, which will in turn improve children’s skills. But the reason that low-income parents parent their children differently than high-income parents is not a causal result of the low income itself. Improving parents’ household income would be laudable for many reasons, but experimental evidence shows that giving parents cash payments after they have a child neither changes parental investments nor changes the child’s skills. [Note from Diane: I disagree. Making cash payments is not the same as improving family socioeconomic status; investing in good jobs, housing, and long-term improvements in SES would make a huge difference.]

Instead, we need to support parents in directly changing what they do. Our experimental research on specific parent behaviors that boost child skills points to the importance of reading and talking to children. Analysis we conducted of the American Time Use Survey shows that on average, however, only 21% of mothers of children ages 3 to 6 report spending daily time reading with their child, only 30% report any daily time playing games with them, and only 11% report daily time dedicated to “listening or talking with” their child.

Worse, many parents are misinformed about how to prepare their young children for school. According to a survey we conducted with 2,000 parents in Chicago, about 25% more parents thought it was essential that children know the alphabet before starting school than thought it was important to spark children’s curiosity.

But this is misguided. Children will eventually learn the alphabet and how to count to 50. Especially for parents with less than a four-year college degree, language interactions with young children – parental storytelling, reading books and asking questions about them – along with math interactions such as playing with shape blocks and reading books about numbers are correlated more strongly with growth in children’s language and math skills than activities such as teaching the alphabet and counting or practicing letter sounds and how to calculate simple sums.

We do a disservice to parents by not redirecting their attention from rote skills, such as memorizing letters, sounds and numbers, to more open-ended inquiry. But researchers are limited as well. We need many more resources devoted to improving high-quality research on understanding precisely what types of parent engagement build the child skills necessary for success in later life. We also need much more research on how to boost parents’ capacity for child skill-building.

But first we must acknowledge that mothers, fathers and other caregivers play a crucial role in building children’s skills. Second, we have to acknowledge that as a nation, we have an interest in what parents do. Children are not just the property of their parents. They are the nation’s future.

Their schooling can only build upon the foundation that parents provide. The United States spends more on education per pupil and less on supporting parents than almost any other wealthy country. The government needs to expand its vision of what it means to support childhood development and invest in helping parents create nurturing learning environments at home in the years before formal schooling begins.

We should signal the value children have for the nation by making work compatible with raising children through family leave, providing access to health care for all children and caretakers and offering free access for children to libraries and museums where they can build a love of learning.

We should also explore new solutions, such as providing digital libraries and utilizing technology in innovative ways to support parents in helping their children learn. Evidence from our recent research shows that this can increase parental reading, boost child language development and close the socioeconomic gap in children’s language skill.
