7. A principal advised that a teacher had intervened with a Year 3 student in the numeracy test
8. A parent complained that a teacher had given verbal prompts and placed notes on answers that needed to be changed to help a student during the language conventions test
9. A School Education Director advised that a Year 3 student possibly had prior knowledge of test content as he claimed his mother (a teacher) went through it with him the previous night

That might explain if any school suddenly jump the rank.
Consistency of the ranking will be a good reference.

我不认为作弊事件会影响有学校在成绩上（注意不是排名）会突然的跃升。
NAPLAN成绩的突然上升和直线下降，基本上就会发生在小规模的学校上，按照墨尔本大学的教授Margaret Wu的说法，小规模的定义为“学生人数少于280人的小学，或者，学生人数少于240人的中学”。
NAPLAN考试的最大问题不是在于是否有老师在帮助学生作弊这样的事件，因为如果你相信这是一个普遍现象的时候，那么这个国家的教育系统老早就垮了。

最大的问题是在于“幅度误差”（a margin of error）。

学生的每一次考试都会有幅度误差。也就是说，当孩子们相同的（或者相似的）考试再考一次的话，他们可能会得到一个完全不同的成绩。孩子们参加同样难度考试多次考出来的最高分数和最低分数之间的相差值就被称为幅度误差。

对于NAPLAN考试，因为每科目只有大概40道考题，幅度误差为上下12%。所以，有一个学生的NAPLAN考试中得了68分，就意味着说，他/她如果在考一次的话分数可能是80分，也可能是56分。或者，你可以把上面的表述理解成，40道题目里的答对的题目有5道的误差，一个孩子40道里答对了25道，其实是表示他/她在下一次相似的考试中可能答对30题，也有可能只答对20题。

单个学生身上的幅度误差造成了班级平均水平统计上的大误差，因为班级平均水平的统计是把所有单个学生的分数相加，然后除以班级学生人数。所以，在就有了一个很大的班级平均层面上统计的幅度误差。

墨尔本大学的教授Margaret Wu说，班级平均统计上的幅度误差有大概10%。

My School网站并不公布单个学生的NAPLAN成绩，也不会公布单个班级的平均成绩，网站只公布整个学校的平均成绩。

但是问题就在于，规模小的学校每个年级只有一个班级，所以学校的平均成绩其实就是班级的平均成绩。

这个事实引来了严重的问题，你可以想象下，My School网站里公布的有一个学校的NAPLAN平均成绩，其实是5个孩子的成绩，因为这个学校相关年级里参加考试的学生只有5个人！

由此你可以预见这样小的学生会对最终NAPLAN的成绩有多么大的影响，比如考试当天班级里最聪明的孩子生病没来学校考试，或者，考试那天，5个孩子发挥都不理想。。。

结论是那些人数很少的学校NAPLAN成绩的排名不可靠，但不是因为作弊，而是因为幅度误差的关系。

考试早结束了.按道理说.这些作弊的事情早应该上报了.为什么突然现在出来了呢?

谢谢解析。。。。。。。。。
很有用。。。可惜没法加分

谢谢那么详细的解释,谁叫我变成了足迹焦虑父母,每次看新闻都成了选择性阅读,一看见这些有关教育之类的,就特别注意.
贴出新闻是希望父母可以了解NAPLAN只是一个参考,需要有一个客观的分析和评价,而不是作为选择学校的唯一准则.
另外我希望努力发言,可以尽早换鞋.我还欠着PurpleRipples贡献2011 NAPLAN排名的分呢.
