How We Determine the Awards

STEP 1 | Students perform better than expected in their state.

We looked at reading and math results for students on each state's proficiency tests and then factored in the percentage of economically disadvantaged students, who tend to score lower.

STEP 2 | Disadvantaged students perform better than state average.

We compared each school's math and reading proficiency rates for disadvantaged students - black, Hispanic and low-income - with the statewide results for these student groups and then selected schools that were performing better than their state averages.

STEP 3 | Student graduation rates meet or exceed a national standard

We excluded schools from consideration if their graduation rates were lower than 75 percent - a threshold that is higher than a federal law that requires states to give extra resources to schools below 67 percent.

STEP 4 | Students are prepared for college-level coursework.

We calculated a College Readiness Index, which is based on the school's AP participation rate and how well the students did on those tests. Tiebeakers were used to determine ranks of schools that achieved the same College Readiness Index

特许学校是公校的另一种形式，也是接受state funding的，纳税人的钱供起来的，不收学费的。

抽签就是一种筛选，一般只有有把握学好的才会去抽签。BASIS而且靠大量淘汰不合格的学生来保证高年级学生的水准。这个绝对是负面榜样。

BASIS有很多直升的，从K进去了直升12年级，只要不走，学期考试合格就升级，一直到高中。

如果毕业的只有入学的1/3，这1/3的成绩本来就在top 1/3，更别人全毕业的当然好多了。

公平的比较是入学时测学生智商，毕业时看毕业了多少。两项都差不多的才能比较，做的好的才说明学校好。而且不能光看考试成绩，因为不同学校侧重点不一样。

没做研究就别说了。
本地新闻报道，第一名Scottsdale今年毕业生有80-90名，我刚去tour完Scottsdale的K，负责任地说K入学的学生也就是150-160。各地高中的学生人数都是呈现随着年级递增人数减少的态势，12年级毕业的学生超过K入学人数的1/2了。校长也承认，原来没有名次的时候retention rate确实不高，但有名次后大大提高了。再说，走掉的学生不是都被淘汰了，也有被提高了，拿着本州或外州私立高中奖学金走掉的学生也不少，当然也有跟不上自己转学的。BASIS学生11年级就能达到AZ高中毕业requirements，没等到12年级就去读大学的也有；12年级在BASIS就是把自己profolio刷得再漂亮一点，为读名校添砖加瓦而已。据说，5-6年级之后BASIS不会再招新生了，因为已经拉下太多，进去了也赶不上。Anyhow，K报名抽签的就400多抽160，能进去再说吧。

你自己去看看wikipedia上的介绍，不要老听校长的话，那自然是都往好里说。

校长就说retention rate提高了，wiki和新闻谁更可信真不好说。
