New study: Tennessee pre-K program provides no educational benefit over control group

This is the most thorough study that I have ever seen evaluating the effectiveness of pre-K programs. The study was done by researchers at Vanderbilt University.

The study was reported on by the well-respected but leftist Brookings Institute.

They write:

State investments in center-based school readiness programs for preschoolers (pre-K), whether targeted for poor children or universally implemented, have expanded more rapidly than evaluations of their effects. Given the current interest and continuing expansion of state funded pre-K, it is especially important to be clear about the nature of the available evidence for the effectiveness of such programs. Despite widespread claims about proven benefits from pre-K, there is actually strikingly little credible research about the effectiveness of public pre-K programs scaled for statewide implementation.

Like many states that became interested in scaling up a state funded pre-K program in the early 2000’s, voluntary pre-K (TNVPK) was introduced in Tennessee in 1996 as a way to provide academic enhancement to economically disadvantaged children. It expanded in 2005 to an $85 million-plus statewide investment serving 18,000 Tennessee income-eligible children in 935 classrooms across all 95 counties.

Launched in 2009, the TNVPK Effectiveness Study, a coordinated effort between Vanderbilt’s Peabody Research Institute and the Tennessee Department of Education, is a five-year evaluation study funded by the US Department of Education, Institute for Education Sciences. It includes the first randomized control trial of a scaled up state funded pre-K program and the first well-controlled comparison group study of the effects of program participation as children progress through elementary school..

Policymakers and proponents often cite some of the famous early studies of pre-K programs that have shown long term benefits extending into adulthood for the participating children. But those were studies of especially complex programs that are unlike scaled-up public pre-K in many ways. The Vanderbilt study is the first rigorous controlled longitudinal study to be conducted on a large-scale state-funded pre-K program.

And here is a summary of the results:

Standard score results from pre-K through 3rd grade on a composite measure that averaged the six achievement subtests are presented from baseline forward in the graph below.

As is evident, pre-K and control children started the pre-K year at virtually identical levels. The TNVPK children were substantially ahead of the control group children at the end of the pre-K year (age 5 in the graph). By the end of kindergarten (age 6 in the graph), the control children had caught up to the TNVPK children, and there were no longer significant differences between them on any achievement measures. The same result was obtained at the end of first grade using two composite achievement measures (the second created with the addition of two more WJIII subtests appropriate for the later grades). In second grade, however, the groups began to diverge with the TNVPK children scoring lower than the control children on most of the measures. The differences were significant on both achievement composite measures and on the math subtests. Differences favoring the control persisted through the end of third grade.

In terms of behavioral effects, in the spring the first grade teachers reversed the fall kindergarten teacher ratings. First grade teachers rated the TNVPK children as less well prepared for school, having poorer work skills in the classrooms, and feeling more negative about school. It is notable that these ratings preceded the downward achievement trend we found for VPK children in second and third grades. The second and third grade teachers rated the behaviors and feelings of children in the two groups as the same; there was a small positive finding for peer relations favoring the TNVPK children by third grade teachers, which did not meet traditional levels of statistical significance.

Results graph:

TNVPK data: pre-K program is in red, baseline is in blue
TNVPK data: pre-K program is in red, baseline is in blue

We are already seeing that cheap daycare in high-tax, big government provinces like Quebec cost a lot, and produce negative results. And of course Hillary Clinton is a longstanding advocate of universal pre-K. As a Senator of New York, she introduced a universal pre-K plan that would cost $10 billion over 5 years. President Barack Obama’s own Preschool for All plan would cost $75 billion over 10 years. This Vanderbilt study should cause us to question whether the policies of the secular left, pushed largely because of emotions and ideology, are worth the tens of billions of dollars they want to take from us. And if you take tens of billions of dollars out of families, then families on the margin will have to give their children to the state to raise. And that includes Christian families, who would no longer be able to afford a stay-at-home mother.

Now, taking children away from parents so that their mothers can work is seen as a worthy goal by those on the secular left. First, communally raising the children is “good” because it removes inequalities between single mothers and traditional working-husband homes. Second, making it easier for women to “go fatherless” is “good” because fathers are not to be trusted to teach their children about morality and religion. That is best left to secular government workers. Third, mothers who choose to marry good providers pay less in taxes if they choose to stay home with their kids and not work. That is “bad” because the government wants more taxes, so they can spend it on vote-buying social programs. Fourth, children who form stable bonds with their parents are less likely to become dependent on the government, meaning their allegiance cannot be bought with government handouts. That is also “bad”. Fifth, it is also “bad” that children who grow up with stay-at-home mothers are more likely to develop empathy and morality, which gives them an independent standard by which to judge the government’s actions.

Study: non-family daycare linked to anti-social behavior in children

From the UK Telegraph.

Excerpt:

Academics at Oxford University discovered that exposure to some forms of early education contributed to bad behaviour and could be linked to emotional problems.

The study, based on an analysis of infants from almost 1,000 families, showed that the strongest influence on children came from within the home itself.

Children raised in poor families with high levels of parental stress or mental health problems were most at risk of developing emotional problems by the time they started school, it emerged.

The research also uncovered trends relating to children who were in formal child care — away from their parents.

The disclosure will revive debate over the best way to raise children amid a surge in the number of under-fives enrolled in nurseries and with childminders in the past 20 years. Figures from the Department for Education show that 441,000 children under five are in day nurseries while another 272,000 are being looked after by childminders.

[…]In the Oxford study, researchers recruited 991 families with children aged three months. Mothers had an average age of 30.

Researchers assessed children at the age of four through questionnaires about their behaviour and emotions completed by teachers and parents. They also observed care provided by mothers and observed non-parental care for at least 90 minutes for those children placed in formal childcare settings.

The report, published in the journal Child: Care, Health and Development, said that “children who spent more time in group care, mainly nursery care, were more likely to have behavioural problems, particularly hyperactivity”.

The study, led by Prof Alan Stein, of Oxford’s Department of Child and Adolescent Psychiatry, found that “spending more time in day care centres, over the total period was a predictor of total problem scores”.

“Children who spent more time in day care centres were more likely to be hyperactive,” it said. “Children receiving more care by childminders were more likely to have peer problems.”

The authors added: “The findings in relation to childminding suggest that it might be out of home care rather than group care that raises the risk of behavioural difficulties.”

The researchers also tracked other forms of early years care and found benefits to different approaches.

They found that children who spent more time in pre-school playgroups – normally for a few hours a day, rather than a full-time nursery – had fewer problems.

More time with a nanny in parents’ own home predicted higher levels of “pro-social behaviour”, showing willingness to help others, it emerged.

The study said: “These findings suggest that interventions to enhance children’s emotional and behavioural development might best focus on supporting families and augmenting the quality of care in the home.”

A study like this will be useful when debating people with open minds, but hardcore feminists and socialists, who want women to work in order to fund bigger government, will not be moved. Because for them, it’s not about evidence. It’s about ideology. That’s why we have to be careful about letting people like that get elected.
