First they choose to attack the comparison, now they want to cherry pick the results. Too funny.
First, your theory of the 10th grade being the "sum of what a child" learns does not hold water. That would only apply if you were looking at the exact same kids over the course of their education. That is not the case for any school, particularly the charter school which has very high attrition rate as compared to the districts that send kids there. (A deeper analysis would show that their special ed kids leave at an alarming rate, which skews their high school results up).
Second, if you have toddler and are looking at applying for the charter school lottery, it may matter to you that the Melrose district vastly outperforms the MV charter school at the elementary levels.
I'm happy to drop this; but I now find it amazing that people cannot accept the straight forward comparison of the two schools. It also does lead one to ask the question as to why are Melrose taxpayers funding a charter school that is under performing the district?
