The Latest Homeschool Study

I am sure Homeschool Legal Defense would not mind me sending you all this email they sent out. If you would rather read it on HSLDAs web site go to <http://www.hslda.org/docs/news/200908100.asp>http://www.hslda.org/docs/news/200908100.asp

Just to explain to those who may not know, Percentile is not the same as percentage. Imagine we give a test to 100 students. A child who scores in the 87th percentile scored better than 87 of the 100 students that took the test.

The highest score possible would be the 99th percentile, or “scored higher than 99 out of 100 of the students.” Standardized tests are written so the mythical “average public schooled” child will score at the 50th percentile. If the average ps child score was higher or lower, they would rewrite the test to bring the average back to the 50th. It is a well known fact that public school children who are male, poor, darker skinned, and from less educated parents score much lower than those who are female, rich, white or Asian, and from college graduate parents. The tests confirm this every year all over the country. Private schooled children generally score in the high 60-70th percentile.

The last piece of major research looking at homeschool academic achievement was completed in 1998 by Dr. Lawrence Rudner. Rudner, a professor at the ERIC Clearinghouse, which is part of the University of Maryland, surveyed over 20,000 homeschooled students. His study, titled Home Schooling Works, discovered that homeschoolers (on average) scored about 30 percentile points higher than the national average on standardized achievement tests.

This research and several other studies supporting the claims of homeschoolers have helped the homeschool cause tremendously. Today, you would be hard pressed to find an opponent of homeschooling who says that homeschoolers, on average, are poor academic achievers.

There is one problem, however. Rudner's research was conducted over a decade ago. Without another look at the level of academic achievement among homeschooled students, critics could begin to say that research on homeschool achievement is outdated and no longer relevant.Recognizing this problem, HSLDA commissioned Dr. Brian Ray, an internationally recognized scholar and president of the non-profit National Home Education Research Institute (NHERI), to collect data for the 2007-08 academic year for a new study which would build upon 25 years of homeschool academic scholarship conducted by Ray himself, Rudner, and many others.Drawing from 15 independent testing services, the Progress Report 2009: Homeschool Academic Achievement and Demographics included 11,739 homeschooled students from all 50 states who took three well-known tests-California Achievement Test, Iowa Tests of Basic Skills, and Stanford Achievement Test for the 2007-08 academic year.

The Progress Report is the most comprehensive homeschool academic study ever completed.The ResultsOverall the study showed significant advances in homeschool academic achievement as well as revealing that issues such as student gender, parents' education level, and family income had little bearing on the results of homeschooled students.

There was little difference between the results of homeschooled boys and girls on core scores.

• Boys-87th percentile
• Girls-88th percentile

Household income had little impact on the results of homeschooled students.

• $34,999 or less-85th percentile
• $35,000-$49,999-86th percentile
• $50,000-$69,999-86th percentile
• $70,000 or more-89th 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
• One parent has a college degree-86th percentile
• Both parents have a college degree-90th percentile

Whether either parent was a certified teacher did not matter.

• Certified (i.e., either parent ever certified)-87th percentile
• Not certified (i.e., neither parent ever certified)-88th percentile

Parental spending on home education made little difference.

• Spent $600 or more on the student-89th percentile
• Spent under $600 on the student-86th percentile

The extent of government regulation on homeschoolers did not affect the results.

• Low state regulation-87th percentile
• Medium state regulation-88th percentile
• High 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.Final ThoughtHomeschooling 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.
