I needed to take a look at the connection between household construction and pupil achievement by household revenue. Single-parent households are way more frequent in low-income communities and I didn’t wish to conflate achievement gaps by revenue with achievement gaps by household construction. For instance, 43 p.c of low-income eighth graders reside with just one dad or mum in contrast with 13 p.c of their high-income friends. I needed to know whether or not children who reside with just one dad or mum carry out worse than children with the identical household revenue who reside with each dad and mom.
To research the newest knowledge from the 2024 NAEP examination, I used the NAEP Knowledge Explorer, a public device developed by testing group ETS for the Nationwide Middle for Training Statistics (NCES). I instructed an ETS researcher what I needed to know and he confirmed me tips on how to generate the cross-tabulations, which I then replicated independently throughout 4 exams: fourth- and eighth-grade studying and math. Lastly, I vetted the outcomes with a former senior official at NCES and with a present employees member on the governing board that oversees the NAEP evaluation.
The evaluation reveals a putting sample.
Amongst low-income college students, achievement differs little by household construction. Fourth- and eighth-grade college students from low-income households rating at roughly the identical stage whether or not they reside with each dad and mom or with just one dad or mum. Two-parent households don’t confer a measurable tutorial benefit on this group. Fourth-grade studying is a superb instance. Among the many socioeconomic backside third of scholars, those that reside with each dad and mom scored a 199. Those that reside with simply mother scored 200. The outcomes are nearly an identical and, if something, a smidge increased for the children of single mothers.
As socioeconomic standing rises, nevertheless, variations by household construction develop into extra pronounced. Amongst middle- and high-income college students, these dwelling with each dad and mom have a tendency to attain increased than their friends dwelling with just one dad or mum. The hole is largest among the many most prosperous college students. In fourth grade studying, for instance, increased revenue children who reside with each dad and mom scored a 238, a whopping 10 factors increased than their friends who reside with solely their mothers. Specialists argue over the that means of a NAEP level, however some equate 10 NAEP factors to a college 12 months’s value of studying. It’s substantial.
Household construction issues much less for low-income pupil achievement
Nonetheless, it’s higher to be wealthy in a single-parent family than poor in a two-parent family. Excessive-income college students raised by a single dad or mum considerably outperform low-income college students who reside with each dad and mom by at the least 20 factors, underscoring that cash and the benefits it brings — equivalent to entry to assets, secure housing, and academic assist — matter excess of family composition alone. In different phrases, revenue far outweighs household construction relating to pupil achievement.
Regardless of the NAEP knowledge, Jonathan Butcher, appearing director of the middle for schooling coverage on the Heritage Basis, stands by the competition that household construction issues tremendously for pupil outcomes. He factors out that analysis because the landmark Coleman report of 1966 has persistently discovered a relationship between the 2. Most lately, in a 2022 American Enterprise Institute-Brookings report, 15 students concluded that youngsters “raised in secure, married-parent households usually tend to excel in class, and customarily earn increased grade level averages” than youngsters who will not be. Two latest books, Brad Wilcox’s “Get Married” (2024) and Melissa Kearney’s “The Two-Guardian Privilege” (2023), make the case, too, and so they level out that youngsters raised by married dad and mom are about twice as more likely to graduate from faculty than youngsters who will not be. Nonetheless, it’s unclear to me if all of this evaluation has disaggregated pupil achievement by household revenue as I did with the NAEP knowledge.
Household construction is a persistent theme for conservatives. Simply final week the Heritage Basis launched a report on strengthening and rebuilding U.S. households. In a July 2025 publication, Robert Pondiscio, senior fellow on the American Enterprise Institute, a conservative assume tank, wrote that “the best intervention in schooling isn’t one other literacy coach or SEL program. It’s dad.” He cited a June 2025 report, “Good Fathers, Flourishing Children,” by students and advocates. (Disclosure: A bunch led by one of many authors of this report, Richard Reeves, is among the many funders of The Hechinger Report.)
That conclusion is partially supported by the NAEP knowledge, however just for a comparatively small share of scholars from increased revenue households (The share of excessive revenue youngsters dwelling with solely their mom ranges between 7 and 10 p.c. The one-parent charge is increased for eighth graders than for fourth graders.) For low revenue college students, who’re Pondiscio’s and the students’ major concern, it’s not the case.
The info has limitations. The NAEP survey doesn’t distinguish amongst divorced households, grandparent-led households or same-sex dad and mom. Joint custody preparations are possible grouped with two-parent households as a result of youngsters could say that they reside with each mom and father, if not on the identical time. Even so, these nuances are unlikely to change the core discovering: For low-income college students, tutorial outcomes are largely related no matter whether or not they reside with each dad and mom the entire time, a few of the time or solely reside with one dad or mum.
The underside line is that calls for brand new federal knowledge assortment by household construction, like these outlined in Challenge 2025, could not reveal what advocates anticipate. A household’s checking account issues greater than a marriage ring.
