School District 5 year SAT scores a statistical shell game

According to the School Districts Spring 2011 Assessment Report, MA students SAT's often score near the national and state average. The way the data has been manipulated though is convoluted and doesn't really compare apples to apples.

• 77% of Moultonboro Academy students on average take the SAT'sat least once.  The state average is 63% of seniors so it's not clear whether the MA numbers also include juniors who take the SAT's in the spring and can retake it in the fall as seniors. It would be a much more accurate comparison if they compared seniors to seniors. 
• The report indicates that the data used for public schools uses average scores of public high schools, while the MA data is the best single score each student received. 
• The report in an effort ( in their words) to equalize data, took the scores of the top 63% of MA scorers, and compared that to the 63% NH SAT takers average scores and determined that the MA scores far exceeded the state of NH average. Of course they do, but it's not a valid comparison. How would the top 63% of NH SAT test takers compare to our top 63%? 

Confused yet? Overall, when you look at the 5 year averages for all MA test takers compared to the average of all NH test takers, the scores are good, but remarkably average. Hardly stellar achievemen
