In recent times and in various countries there has been considerable p
ressure to raise educational standards and levels of student achieveme
nt. As a means to that end there has been a drive from the political r
ight to greater diversity of school provision and an increase in paren
tal choice of school. In theory, this market approach should be self-c
orrecting and so allowed to run its course without state intervention.
The political left, whilst sharing the aspiration to excellence in th
e school system, has been thrown into a defence of some of the status
quo ante and so at times into an anti-libertarian position. It is argu
ed that diversity and choice in the UK are defensible, drawing from bo
th left and right libertarian positions. Though the two are not by any
means always compatible, some combination is intellectually tenable a
nd a possible basis for policy. In this modified libertarian approach,
potentially acceptable to both left and right, diversity and choice a
re taken to be desirable unless and until (1) some convincing argument
and evidence can be adduced that the costs greatly outweigh the benef
its, and (2) it can be shown that any costs incurred cannot be reduced
or overcome by limited state intervention. If these conditions cannot
be met, people will not be persuaded voluntarily to forgo diversity a
nd choice and/or there can be no adequate justification for politician
s to deny diversity and choice. It is argued that, from the point of v
iew of the libertarian, diversity and choice need to be positively sti
mulated to sustain democracy in pluralist societies. However, diversit
y and choice cannot be left to market forces, but several types of sta
te intervention are justified to protect the vulnerable from the unint
ended and inequitable side-effects of market forces. In the UK, it is
incompatible with a libertarian position to return to either a pre-196
5 selective system or to a pre-1979 comprehensive system. The most pro
mising way of balancing individual rights and collective welfare is to
retain an anti-selective comprehensive principle within a system char
acterised by unaccustomed and innovative diversity and choice.
