One of the strongest arguments for the raising of the school leaving age (ROSLA) 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 wouldn't 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.

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.

It is clear from this and many other proofs that many children are still leaving school too early

to benefit from the prizes money, social respectability, and interesting jobs which higher

education gives. It is clear too that the reasons why such children leave have much to do with

their social background. Their parents often need the extra money another money-earner would

bring in; they don't value education for itself because their own was probably dull and unhappy.

It is not so much that they force their sons and daughters to leave school, rather than they tend

to say, "It's up to you."

2. People would like to think that ______.

A. equal numbers of poor and wealthy children reach university

D. fewer boys than girls stay at school after 16
