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.
Actually 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.
percentile is the score of a student
factored by the average first scores of all the students for the last 3 years.
and then the ssat puts a percentage on it
Let say student gets 790 in one test for math
for the last 3 years, the top 1% of the students are getting 785 average, then the student will have 99 percentile.
If the student got 780, and the average of the top 1% of students is 785 and top 2 percentage is 775, then the student will be 98 percentile
Note this is not percentage but percentile
Percentile means % above the percentage of 100 percentage of students
SSAT Board已对国际考场的考生设立了专门的标准组进行排名比较的。“on a Standard test date in the previous three years” 这应该是指任何一个月的一次考试吧,还是你说的一定要同一月份啊?比如SSAT 10,11,12月三次考试,考生参加任何一月考试的成绩对会进入排序吧。
