Comprehensive
Schools.

Royal assent was given on 22 November, 1976, to the bill to require
local education authorities to have regard, in all their duties relating to
secondary education, that such education should be provided in schools that
admitted pupils without reference to ability or aptitude and to empower 1
the Secretary of State to call the proposals to complete reorganization
in cases where he felt progress or further progress was necessary.

But most of the 2 comprehensive schools which exist today
were started before secondary reorganization. They were introduced more than
fourty years ago, and now 75% of all
secondary schools are comprehensive. Pupils go to them automatically 3
regardless of intelligence. However, some comprehensives and many secondary
schools do not have the full range of academic courses for six-formers. Pupils
can transfer either to a grammar school or to a six-form college to get the
courses they want.

A comprehensive school is a school for all pupils of secondary school
age in a school district. These schools cover, in fact, all the work done in
grammar, modern and technical schools. They offer a wide range of general and
vocational subjects. They tend to be large: more than a quarter have over 1,000
pupils and nearly half of them have more than 800.

Much is done in England
for assistance to the development of a fully comprehensive system of education.
The word “comprehensive” expresses not only the idea that the schools in
question take all the children of a given area, without selection, but also
that they should offer a wider range of courses than any one of the traditional
types of school. For this reason they are usually bigger than the traditional
types.

Some of the comprehensive schools are simply country secondary schools,
some are large purpose built comprehensives on new housing estates, others are
housed in older buildings often some distance apart. If a council decides on
comprehensive schools, there is no selection by examination and all pupils go
on from primary school to the comprehensive school in their area.

Many of these schools preserve the А, В, С
relationship among the children, but the children are allowed to change streams
according to their progress. Most, but not all of these schools have some kind
of selection inside the school. The children make a choice of subjects they
want to study. Most of the schools are mixed.

The comprehensive system is considered by many to be a fair one,
offering wider opportunities for many more pupils and giving the 4
slower pupils a better chance of catching up.
