Public Schools Are Better.

Here is the link where I read that.

Here is a bit of what this study had to say (click on it to read the actual study):

"To summarize the most important findings once demographic and location differences were controlled:
• Public schools significantly out-scored Catholic schools (by over 7 points in 4th grade, and almost 4 points in 8th grade).
• Of all private school types studied, Lutheran schools performed the best. 4th grade scores in Lutheran schools were roughly 4 points lower than in comparable public schools, but were (a statistically insignificant) 1 point higher at the 8th grade.
• The fastest growing segment of the private school sector, conservative Christian schools, were also the lowest performing, trailing public schools by more than 10 points at grades 4 and 8.
• Charter schools scored a significant 4.4 points lower than non-charter public schools in 4th grade, but scored (a statistically insignificant) 2.4 points higher in 8th grade."
