SSAT的百分比釋疑
根據(jù)SSAT 官方有關(guān)SSAT Percentile 的摘錄如下:“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.
想請(qǐng)教業(yè)內(nèi)同仁,最后這句話的理解是否為:學(xué)生第一次參加的SSAT的各單項(xiàng)成績歸入標(biāo)準(zhǔn)組進(jìn)行百分比統(tǒng)計(jì),但不會(huì)影響此學(xué)生的第二三次考試成績的占比?還是第一次成績也會(huì)影響第二三次考試的排序。

這只是說明SSAT統(tǒng)計(jì)百分比排名的數(shù)據(jù)是根據(jù)過去三年學(xué)生第一次考的成績來計(jì)算的。后面考試的成績不計(jì)入統(tǒng)計(jì)數(shù)據(jù),但計(jì)入個(gè)人成績的。換句話話,如果你考的成績百分比是50%,成績比你高的一般會(huì)多于成績比你低的,因?yàn)槎嗫紟状?,成績一般?huì)更高一些。

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.
