Examination Bias
Performances of populations of all living things, grass, microbes, insects, apes or humans, will match this curve. That is, when the population is tested for any attribute or ability, and - of course - if the test is fair.
[NOTE 2 A 'real' population will have slightly more at G-, and G level due to accident, trauma and early damage.]
Figures for human IQ percentages follow the Normal Curve, and are displayed at intervals - labelled "Fair Test" - in results below.
These results are for the British "General Certificate of Secondary Education" and GCSE `A-level'. An annual examination - its grades determine which candidates go on to college (university) education.

They seem confusing at first but when we examine them one subject at a time we can see that various patterns emerge.
Curve moves to the
right
if test is EASY,
i.e.more candidates get HIGH grades;
and to the left if test is
HARD.
i.e. more candidates get LOW grades
BUT - if the curve is mis-shapen then part of the population is being tested differently, i.e. some form of cheating
is going on.
In subjects perceived as demanding but non-prestige, ie Home Economics
(linkback here) and Computer Studies (linkback here) the results tend to be more or less normal, but in more prestigious subjects, i.e. Biology, Chemistry andPhysics (linkback here) there is a definite bulge in high pass marks.
This phenomenon is visible even in Mathematics and English Literature (linkback here).
Prestige subjects tend to be emphasised in elite schools - i.e. private fee paying schools. One could be excused for thinking, as erroneously claimed by elite's Social Darwinists, 'that the children of the rich might be brighter'.
However results for subjects that are practically exclusive to elite schools show the reality:- thus in Latin, Greek, Classic Civilisations (linkback here) it is clear that testing is up to 7 to 10 times easier than the "Fair Test".
Outcomes are therefore very different for "democratic" subjects :-
Computer studies
ie. 'fair' - 9.5 % got A pass
compared with "elite" subjects:-
Greek
ie. 'easy' - 71.1% got A pass
Inevitable conclusions :-
1 - elite schools get preferential treatment. Quite dull candidates from elite schools are given high passes.
See hierarch.txt & devices
2 - high grade non-elite candidates are being cheated out of high passes they deserve, but which are awarded to low grade elite candidates.
3 - all non-elite candidates are suffering lower grade marks as a result.
[National exam boards annually adjusted all marking standards to ensure only the `required' number of candidates get pass marks.]
If you have tables of British national or local results, either pre-GCSE, GCSE or further, OR other nation's figures, check them out yourselves for fairness.
N.B. After our analysis, in 1995/6 "Perceptions" editor contacted a major British broadsheet, a national newspaper with an education remit.
Education contact on that journal admitted that although they lacked the will to make similar analyses, they have received inside information proving that elite schools have been receiving preferential examination treatment
in prestige subjects.
She quoted specific cases of elite schools cheating in English Literature exams.
But she could not explain why her newspaper was not campaigning against this corruption -
- but, as she is ruled by self-interested editors see refer and proprietors, we didn't feel we should criticize her for their failings.
IN UK YOU CAN NO LONGER CHECK ANNUAL RESULTS, WHICH HAD BEEN PUBLISHED IN FULL - AS SHOWN ABOVE;
SINCE WE RAISED THESE CONCERNS, THE POLITICIANS OR THE BUREAUCRATS HAVE DECIDED TO PUBLISH RESULTS IN A NEW LAYOUT - BELOW.
New layout, as you can see, is less efficient, but, importantly, prevents any check for fairness
WHY?
FROM THEIR REACTION YOU COULD BELIEVE THAT THE CORRUPTION WAS KNOWN BUT IS NOW MEANT TO BE SECRET
UPDATE Sept. 2007
Admission that `Universities still cheat to favor the elite'.
Estimate:-
junking 33% of the curriculum - so removing misinformation and ending 'curriculum rush';
reintroducing valuable non-classroom subjects - music, sport, PE, drama, swimming, private reading / private study etc - to the school day;
scrapping homework completely - to prevent damaging class-bias and discrimination;
would substantially improve characters and academic outcomes!
UK's MULTI-EXAM SYSTEM
Why do UK politicians seem always to choose, initially anyway, the most harmful and inefficient methods and systems?
By 2006 - UK's intensive multiple exam system has had the effect of making `valuable' - so far as selfish teachers and heads are concerned - only those students pretty well guaranteed to achieve good `passes'.
At all stages the others are deemed `worthless' - by selfish teachers and heads - because the league tables are biased toward pre-selection.
So, at all stages they tend to be abandoned - by selfish teachers and heads - whilst in reality they are most important students of all. They are our future - both as work-force and voters!
[I suspect politicians make those `wrong' choices because they are guided by a civil-service ruled by elitists, who need to preserve privilege and corruption for their own advantage.
Which is why we see this apparent `incompetence' in all matters:- of taxation, education, law, policing and of the electoral system itself.]
