One of the strongest arguments for the raising of the school leaving age has been that it will bring us some way nearer to “equality of opportunity”
Many people like to think of our present system of schooling as providing plenty of steps up the ladder of success for clever children.It would be good to think that no one who is really bright can be missed out when the state system is obviously so complete.It is obvious,for instance,that many children from less wealthy homes reach university or do well in other ways.
Unfortunately,we now have plenty of proofs that many children of every level of ability do much less well than they could.For instance,during the years of national military service it was possible to test the intelligence of all male 18-to-20-year-old.Half of those soldiers who were placed in the two highest ability groups had left school at 15.
还有这点：
It has also been shown that the percentage of
working class children going to university is almost the same now as it was in
1939.One study of 5000 children from birth to 21 years old shows that up to
half the bright pupils from working class homes left school when they reached
16 years old.Moreover,there is no difference in intelligence between the
sexes,but far more boys than girls stay in education after 16.

提高离校年龄的最强有力的论据之一就是,它在某些方面可以带给我们“平等机会”.
许多人喜欢把我们现代的教育系统当成是为聪明孩子提供的步入成功之门的一步步阶梯.这样的想法并不对,国家的教育系统明显已经很完善了,没有一个真正聪明的人会被忽略的.很明显的一个例子,比如,许多来自于贫困家庭的孩子考上了大学,或者在其他领域很优秀.
很不幸的是,我们现在有大量的证据证明,每个能力级别的许多孩子都没有尽他们的能力做.例如,在国家军队参军的那几年,是可以测出所有18到20岁男子的智力的.两个最高能力组的士兵有一半在他们15岁的时候就离开了学校.
也有资料表明,现在,参加工作后再上大学的人数的百分比和1939年是一样的.一份5000个孩子从出生到21岁的跟踪调查显示,超过半数工薪阶层家庭的聪明孩子16岁就离开了学校.而且,虽然智力与性别无关,但是,16岁后仍然留在学校的男生比女生多很多
