SSAT的百分比释疑
SSAT的百分比释疑
根据SSAT 官方有关SSAT Percentile 的摘录如下:“The SSAT Percentile (1 to 99) compares the student's performance on the SSAT with that of other students of the same grade and gender who have taken the SSAT in the U.S. and Canada on a Standard test date in the previous three years. For students who have taken the SSAT more than once, only their first set of scores is included in the norming process.
想请教业内同仁,最后这句话的理解是否为:学生第一次参加的SSAT的各单项成绩归入标准组进行百分比统计,但不会影响此学生的第二三次考试成绩的占比?还是第一次成绩也会影响第二三次考试的排序。

回答于10/29/2014Actually what this means is:
Students will be compared with other students of the same gender and grade for the last 3 years - a pool
For students who take the SSAT more than once, only the first score will go into the pool
This means
Year 1 year 2 year 3 = average score of all the students (but only for the first test that each student takes)
percentile = student's score factor into the average of 3 years
However, the first SSAT test that a student will take will not affect the student's scores of the next test.
So if you are 99 percentile, then you are 1% above the rest of all the students.
