There was little difference between the results of homeschooled boys and girls on core scores.
Household income had little impact on the results of homeschooled students.
$34,999 or less—85th percentile
The education level of the parents made a noticeable difference, but the homeschooled children of non-college educated parents still scored in the 83rd percentile, which is well above the national average.
Neither parent has a college degree—83rd percentile
Whether either parent was a certified teacher did not matter.
Certified (i.e., either parent ever certified)—87th percentile
Parental spending on home education made little difference.
Spent $600 or more on the student—89th percentile
The extent of government regulation on homeschoolers did not affect the results.
Low state regulation—87th percentile
HSLDA defines the extent of government regulation this way:
States with low regulation: No state requirement for parents to initiate any contact or State requires parental notification only.
States with moderate regulation: State requires parents to send notification, test scores, and/or professional evaluation of student progress.
State with high regulation: State requires parents to send notification or achievement test scores and/or professional evaluation, plus other requirements (e.g. curriculum approval by the state, teacher qualification of parents, or home visits by state officials).
The question HSLDA regularly puts before state legislatures is, “If government regulation does not improve the results of homeschoolers why is it necessary?”
In short, the results found in the new study are consistent with 25 years of research, which show that as a group homeschoolers consistently perform above average academically. The Progress Report also shows that, even as the numbers and diversity of homeschoolers have grown tremendously over the past 10 years, homeschoolers have actually increased the already sizeable gap in academic achievement between themselves and their public school counterparts-moving from about 30 percentile points higher in the Rudner study (1998) to 37 percentile points higher in the Progress Report (2009).
As mentioned earlier, the achievement gaps that are well-documented in public school between boys and girls, parents with lower incomes, and parents with lower levels of education are not found among homeschoolers. While it is not possible to draw a definitive conclusion, it does appear from all the existing research that homeschooling equalizes every student upwards. Homeschoolers are actually achieving every day what the public schools claim are their goals—to narrow achievement gaps and to educate each child to a high level.
Of course, an education movement which consistently shows that children can be educated to a standard significantly above the average public school student at a fraction of the cost—the average spent by participants in the Progress Report was about $500 per child per year as opposed to the public school average of nearly $10,000 per child per year—will inevitably draw attention from the K-12 public education industry.
Answering the Critics
This particular study is the most comprehensive ever undertaken. It attempts to build upon and improve on the previous research. One criticism of the Rudner study was that it only drew students from one large testing service. Although there was no reason to believe that homeschoolers participating with that service were automatically non-representative of the broader homeschool community, HSLDA decided to answer this criticism by using 15 independent testing services for this new study. There can be no doubt that homeschoolers from all walks of life and backgrounds participated in the Progress Report.
While it is true that not every homeschooler in America was part of this study, it is also true that the Progress Report provides clear evidence of the success of homeschool programs.
The reason is that all social science studies are based on samples. The goal is to make the sample as representative as possible because then more confident conclusions can be drawn about the larger population. Those conclusions are then validated when other studies find the same or similar results.
Critics tend to focus on this narrow point and maintain that they will not be satisfied until every homeschooler is submitted to a test. This is not a reasonable request because not all homeschoolers take standardized achievement tests. In fact, while the majority of homeschool parents do indeed test their children simply to track their progress and also to provide them with the experience of test-taking, it is far from a comprehensive and universal practice among homeschoolers.
The best researchers can do is provide a sample of homeschooling families and compare the results of their children to those of public school students, in order to give the most accurate picture of how homeschoolers in general are faring academically.
The concern that the only families who chose to participate are the most successful homeschoolers can be alleviated by the fact that the overwhelming majority of parents did not know their children's test results before agreeing to participate in the study.
HSLDA believes that this study along with the several that have been done in the past are clear evidence that homeschoolers are succeeding academically.
Homeschooling is making great strides and hundreds of thousands of parents across America are showing every day what can be achieved when parents exercise their right to homeschool and make tremendous sacrifices to provide their children with the best education available.
