Hi ergo, Excellent topic, and a topic on which I have recently gained some insight and opinion. We've also had the great fortune and benefit of an affiliation with a "faith based" remediation service.
As for the failure of some children to achieve certain proficiency levels in the primary grades, I think there are a myriad of factors. I think alot of it has to do with developmental differences and differing learning styles in the young child. We all "get there" but we don't all get there at the same rate or in the same manner. Developmental differences and differing learning styles are most pronounced early ed. The public system has become overly "standardized", and rigid, with evaluation metrics probably too narrowly defined. Some kids get lost. Imo, the key to overall academic success lies in appropriate primary school ed, a good foundation. And this is often (usually??) specific to the individual child. But more on this later.... I'm kind of too tired to think.
For those who are familiar with my personal situation, we are doing great. Honestly thriving because of an awesome, caring and thoroughly competent private sector remediation service. We are very, very fortunate!!...
