In a 2007 study, "Are Private High Schools Better Academically Than Public High Schools?" the Center on Education Policy (CEP) found that once key family background characteristics were considered, public high school students do as well as private school students. "When we controlled for other factors, family background was the biggest determinator of how a kid was going to do," says Diane Stark Rentner, Deputy Director of the CEP.

The report found that:

1. Private high school students scored no better on achievement tests in math, reading, science and history than their counterparts in public high schools.

2. Private high school students were no more likely to attend college than their public high school counterparts.

3. By age 26, young adults who had attended private school enjoyed no more job satisfaction than those who had attended public high schools and were no more likely to be engaged in civic activities.

The study did identify two exceptions: Kids who attend private school had higher SAT scores. According to the study, "independent private school students do not learn any more than other students as measured on achievement tests, but they do perform better on the SATs." CEP believes this "could mean that students in private schools tend to have higher IQs (aptitude tests are a better measure of IQ than achievement tests) or that private schools are better at honing students' test-taking skills (on which
SAT scores are somewhat dependent)." This, in turn, gave private school students an advantage getting into elite colleges.

Catholic schools run by holy orders did have some positive academic effects, such as slightly higher achievement levels in reading, math and history.
