There are other reasons for the higher Christian scores than just the school (I sent my dau to a Christian and can testify to the superior education). These parents are much more involved (and put their money out to prove it), the students are probably better students to begin with and the teachers go out of their way to insure that students get extra help if needed. And I might add that prayer surrounds these schools, a fact not to be overlooked. Public schools have more levels of students taking the tests, averaging out to a lower average score. Plus most Christian schools are not equipped to take special-needs students and public schools have to.
However, I still think your point is well made. My dau did not particularly like her Christian school, but she really saw the difference in her education when she went to college.
This is an interesting point, but it, too, can be misunderstood.
One could say that Christian school kids are "more intelligent" to begin with, or one could say that Christian kids have a better environment to begin with.
I've seen the McGuffy readers and exams from a different era AND for children far younger. They were pretty tough and the work to meet those standards must have been exceptional.
Given the lower ages of the students, I'd say that the issue is environment. Everyone was expected to learn, and they expected that school work took lots of effort. Christian school kids benefit from a better environment...not from higher "inate" intelligence, imho.
