Economist sees little benefit from full-day kindergarten

KindergartenAcademic gains for children who attend full-day kindergarten programs compared to those who attend half-day programs are so short-lived that policymakers should take a hard look at whether the additional cost of full-day programs is worthwhile, concludes an economist in a recent issue of Economics of Education Review.

“My findings suggest that, on average, the academic returns associated with full-day kindergarten are quite low or non-existent,” writes Philip DeCicca from the Department of Economics at McMaster University in Hamilton, Ont.

DeCicca analyzed kindergarten and 1st grade reading and math test scores for children from 714 schools who attended half-day or fullday kindergarten programs.

While children in full-day programs scored higher in reading and math than their half-day counterparts at the end of kindergarten, those gains had evaporated by the end of 1st grade, the researcher reports. This was true for both girls and boys and black and Hispanic children. In fact, Hispanic children who attended full-day kindergarten programs performed worse at the end of 1st grade than children who attended half-day kindergarten.

“The estimated pattern of results suggests that full-day kindergarten substantially raises the math and reading achievement of children of all races,” the economist writes. “However, these gains are much smaller in magnitude when measured via similar tests just one year later. In other words, the short-run impact of full-day kindergarten has depreciated considerably by the end of first grade.”

For black children, the short-run gains seem to be gone by the beginning of first grade, indicating that the loss is due to “summer fallback”, the economist writes. For white and Hispanic children the gain seems to erode gradually during 1st-grade. The declines are shallowest for whites, he says.

“Given existing socioeconomic differences between the races, it is possible that differences in home environment contribute significantly to the larger losses for Hispanic, and especially black, children,” he writes.

Half-day began during WWII The history of kindergarten dates back to the 1800s when it began as a full-day program, DeCicca writes. During WWII, schools across the country began to cut their kindergarten classes back to a half-day in order to free up additional labor.

Full-day kindergarten reappeared in the 1960s as an intervention to help disadvantaged children catch up to their peers through additional schooling. But, now it has gained popularity among middle class families. Over the past 30 years, the percentage of children in full-day programs has grown from 10% to just over half of U.S. kindergartners.

The push for full-day kindergarten has occurred at the state level, DeCicca writes. Currently, nine state governments mandate full-day kindergarten and 26 provide financial incentives to encourage school districts to provide it.

The rationale for full-day kindergarten is that the more time children spend in school, the more they will learn, the researcher writes. But, detractors warn that an early emphasis on academic learning, at the expense of play time, could harm children emotionally and academically.

Economists have taken little interest in the half-day vs. full-day kindergarten debate, which is surprising, DeCicca says, in view of the enormous attention paid to Head Start and its possible effects on outcomes.

Beyond academic benefits, policymakers also need to consider socialization issues and kindergarten’s role as a child care subsidy in evaluating full-day kindergarten vs. half-day kindergarten, he notes.

    I found your article on all day kindergarten yielding marginal academic results very interesting , especially since I taught 1st grade for 16 years . Initially , when our district went to full day kindergarten , i was highly skeptical about a 5 year old spending a full day in school. However, I noticed a huge difference in reading skills when the all day kindergarten kids reached 1st grade. These students had a greater knowledge of phonics skills : long and short vowels , digraphs ,consonant blends etc. than any other classes I had prior to that group. That is very significant. It gives the student a one up position in word attack skills and therefore a easier if giant step in becoming an early independent reader. I realize your article does assume that this doesn’t matter because at the end of 1st grade , the impact of full day kindergarten loses ground. What concerns me is that testing 1st grade kids might be a little premature in pronouncing all day kindergarten as a minimal impact factor. Might it be more revealing to look for a long term effect of all day kdgn. like the end of 2nd grade ? or even 3rd grade? I would be curious . My point is that reading is a very complex and challenging skill for a 6 year old and any standardized test at that point can not be testing a relatively skilled and strong reader. I am in no way demeaning the concepts in your article but I would breathe a little easier knowing that the student was a little more”test ready” and I could take more credence in your conclusion.

    As a grandmother of a 4.5 year old, my concern is the emotional readiness of a 5 year to attend a full-day program.
    I believe that a young child should be eased into school and the half-day program allows for that.
    A tired child means an emotionally tired child, and this may lead to a child that resists and/or resents school.
    This does not fare well for a child’s future academic success. I want my grandchild to embrace school as I firmly believe if s/he feels positive about schooling, they will fare better in the long run. I believe that the initial temporary gains of a full time kindergarten, are just that, temporary. Better for a child to be emotionally prepared, and happier for the long terms gains. That is where we will succeed. Half day programs should continue to be offered for all kindergartens; not a one size fits all.
