The State of MD just came out with it's annual school readiness report. It is a report of readiness level of children who entered kindergarten in Fall 08.
The report is broken down by county and compares ethnic groups, gender, Free lunch recipients, English as second language and "prior early care." That last referring to whether they were in a public or private pre-k, day care center, family day care or being cared for by a relative.
In Calvert County, private nursery schools have an 89% fully readiness rate out of 211 kids, compared to 69% for public pre-k for 229 kids.
In Charles is 81% for 98 private nursery school students and 74% for the 815 public pre-k kids.
In St. Mary's... 95% for 162 in private school and 77% for 531 public pre-k kids.
But figure that the public schools most likely include all of those designated as "special ed" 127 for Calvert 122 for Charles, 127 for St. M's. Plus all the foster kids, kids whose parents are in jail or are otherwise suffering from socio-economic disadvantages.
I'd say the bottom line is that if you remain active in your child's education, whether you pay for it or not, your child will benefit.
