     We are all interested in equality, but while some people try to protect the school and examination system

in the name of equality, other, still in the name of equality, want only to destroy it.

     Any society which is interested in equality of opportunity and standards of achievement must regularly

test its pupils. The standards may be changed-no examination is perfect-but to have to tests or examinations

would mean the end of equality and of standards. There are groups of people who oppose this view and who

do not believe either in examinations or in any controls in schools or on teachers. This would mean that

everything would depend on luck since every pupil would depend on the efficiency, the values and the purpose

of each teacher.

     Without examinations, employers will look for employees from the highly respected schools and from

families known to them-a form of favouritism will replace equality. At the moment, the bright child from an

ill-respected school can show certificates to prove he or she is suitable for a job, while the lack of certificate

indicates the unsuitability of a dull child attending a well-respected school. This defence of excellence and

opportunity would disappear if examinations were taken away, and the bright child from a poor family would

be a prisoner of his or her school's reputation, unable to compete for employment with the child from the

favoured school.

     The opponents of the examination system suggest that examinations are an evil force because they show

differences between pupils. According to these people, there must be no special, different, academic class.

They have even suggested that there should be no form of difference in sport or any other area: all jobs or

posts should be filled by unsystematic selection. The selection would be made by people who themselves are

probably selected by some computer.
