Felix Thoemmes studies quantitative methods and design for the social sciences. In the research paper described below, he collaborated in the development of a math model to show the causal relationship between the student's age and the likelihood the student will enroll in college. Previously, Dr. Thoemmes collaborated with Dr. Philip Parker of the Australian Catholic University on a study of the effect of the college gap year on persistence in college (https://hdtoday.human.cornell.edu/tag/felix/).

Teens who are old for their grade appear to feel more confident about their academic abilities and are more likely to enroll in college than their younger peers, according to research published by the American Psychological Association.
The study analyzed data from more than 10,000 Australian students who were tracked over a decade and found that the relative age of students in their grade had significant effects. The issue should be considered by government agencies, schools, teachers and parents, especially in enforcing strict regulations about school starting age for students, said lead author Philip D. Parker, PhD, an associate professor of psychology at Australian Catholic University.
“Being young for your grade really does lead to lower academic self-confidence, especially in math, even accounting for student’s actual performance in those subjects,” Parker said. “Further, being young for your grade appears to slightly lower a student’s chances of entering college, and the most likely reason for this is a lower level of academic self-confidence.”
The findings from the study were modest in size, with 58 percent of students who were almost a year older for their grade enrolling in college, compared with 52 percent of students who were almost a year younger for their grade. The study was published in the Journal of Educational Psychology.
In Australia, the United States and other countries, many parents start their children in school late for their grade to gain a future advantage in academics or sports. Those decisions are understandable but ultimately may hurt other students, Parker said. Parents of children who are young for their grade shouldn’t worry about it because the research findings were modest in size, but there are greater implications for school systems and policymakers to create a level playing field for all students, he said.
“It is critical that school systems have a clear and strictly enforced school starting-age policy,” Parker said. “While there may be joy or shame for students who are advanced or held back a grade, educators also need to consider the implications that those decisions will have on other students in their classes.”
The study used data from the Longitudinal Study of Australia Youth, which included 10,370 15-year-old Australians who were surveyed over a decade. The participants, who were born between May 1987 and April 1988, were evenly divided between males and females and consisted of 78 percent native-born Australians, with smaller numbers of first-generation or second-generation immigrants. Three percent of the students identified as being of indigenous descent.
