In summary, the Indian PISA test is fraudulent
Based on
Insufficient sampling
Skewed Sampling towards Rural schools , govt schools, linguistic minority kids,
and many other tricks to avoid sampling brahmins and upper castes and high end private schools
This has been done because this has been influenced by leftists, to magnify Indian problems
and based on the low Indian PISA score, they have already demanded more funding for
Govt schools ( even though they underperform Private schools drastically, ) and they are also demanding
increase in Govt school teacher salary, even though these parasites make 5X more salary than Private school teachers
In short, this is a repeat of the gutter inspector report of Katherine Mayo's 'Mother India'
The Real Indian IQ - G.Subramaniam - 02-24-2012
IQ summary from CA national merit winners and CA STARS population data
Using National Merit list = 135 IQ and SD = 15
It is assumed that the Jewish population is 2% of the white population
The Indian population is 4900, and it contains about 500 muslims from India, Pakistan and Bangladesh
I am ignoring this muslim population and spreading the caste numbers among the rest, which would
give a safety margin of 1 - 2 IQ for Indian castes
White = 97
Muslim = 97
Jat Sikh = 97
Patel = 97
Syrian Xtian = 97
Japanese = 97
Mid-Level Hindu Dravidian Caste = 105
North Indian Kayasth scribe = 105
North Indian Rajput = 109
South Indian Nair Rajput = 109
Indian - California Caste Blend = 109
East Asian = 109
Jew = 110
North Indian Merchant = 110
North Indian Brahmin = 112
South Indian Brahmin = 117

Errors in PISA 2009 Indian scores - part 1
---
For reference I am comparing this against the World Bank report 'Indian Shining, Bharat Drowning'
Making an accurate sample is very difficult in Indian populations, due to effects of caste and poverty
However, I am assuming that the World bank report sampling has not been gerrymandered
In Math, the TIMMS score is as follows
Orissa Avg = 404
Rajasthan Avg = 382
For reference,
Iran Avg = 411
Philippines Avg = 378
Norway = 461
Per Avg scores, these states show up as lower-middle income countries
--
If we move from Avg scores to High International Benchmark Scores of 550
In Iran, 3% cross this level
In Philippines 3% cross this level
In Orissa, 9% cross this level
In Rajasthan, 4% cross this level
In Norway, 10% cross this level
--
So at the Avg Level, these states look like Iran and Philippines, at the High end, they look like Norway
--
The Average Indian scores like Iran, and the Top Indians score like Norway, there is a very distinct High End IQ bulge that is absent in countries with the same Average score
--
At the bottom end,
Orissa 5th percentile = 240
Rajasthan 5th percentile = 220,
At the bottom end, these states look like black Africans
--
Lets now look at the PISA Math scores for TN and HP
TN - 5th percentile = 241
HP - 5th percentile = 223
TN - 50th percentile = 351
HP - 50th percentile = 338
TN - 95th percentile = 468
HP - 95th percentile = 458
--
If we compare the TIMMS for Orissa and Rajasthan vs PISA for HP and TN, we notice that the bottom end is identical
The mean has shifted down by 50 points and the top end has shifted down by 100 points.
--
Next we will investigate why the mean and top-end have down-shifted
One explanation is that per the WIPRO report, TN has the worst, most dumbed down state curriculum and TN scores below the Indian Average, while Orissa despite being much poorer scores near the top for all Indian states, in Govt schools
The Real Indian IQ - G.Subramaniam - 02-25-2012
Errors in PISA 2009 Indian scores - part 2
-----
My hypothesis is that the downshift in the mean and top-end scores is due to deliberate gerrymandering to lower the PISA score. The low PISA score would in turn raise a clamor for more govt money to go to Public schools and Public school teacher salaries. This is in line with leftist NGOs. This gerrymandering could easily be done by a low to mid-level official who had infiltrated the Indian PISA team

Has the complete PISA report
--
Table A.2: Population coverage indices
This shows that in most countries 1% of the schools were sampled for PISA
However, the TN, HP data is so bad, they dont have a clue on what the sampling ratio is
Table A3,
TN had 143 schools appearing for PISA
HP had 66 schools appearing for PISA
Whereas in Costa Rica, 180 schools appeared for PISA
Table A4
TN PISA had 3210 students
HP PISA had 1616 students
Costa Rica PISA had 4578 students
The Population of TN is 65 million, and the Population of HP is 7 million and the population of Costa Rica is 4 million
PISA has no idea, what fraction of the total population of TN and HP were sampled
My first alert is the very small sampling in TN and HP

Errors in PISA 2009 Indian scores - part 3
-----------
http://pisa2009.acer.edu.au/interactive.php
is an interactive website to look at how PISA score changes under various factors
--
My first concern is whether PISA over sampled linguistic minorities deliberately to lower the score
In HP, the medium of instruction is Hindi and the linguistic minorities are Tibetans and Punjabis
In TN, the medium of instruction is Tamil the main linguistic minority is Telegu
--
In the interactive PISA site,
under School variables, SC08Q01 asks 'Is the test language same as the first language of the child'
This would catch linguistic minorities, for example a Telegu child in a Tamil classroom, answering a PISA exam set in Tamil
or
A Tibetan or Punjabi child in a Hindi classroom, answering a PISA exam set in Hindi
Category-1 means over 60% of the students are from a linguistic minority and Category-6 means all students are from the linguistic majority
--
In Tamil Nadu, 75% of the student sample was in Category-1 and they scored 344 mean for PISA math, and
only 20% of the student sample was in Category-6 and they scored 378.
In any good sampling system, 95% should be in category-6 and just 5% of student sample in Category 1
The PISA mean was 351. But for Tamil students answering PISA in Tamil, the score was 378
The gerrymandering artificially reduced score by 27
At 378, the math score is same as Rajasthan in TIMMS
--
In HP, 83% of the student sample was in Category-1 and they scored 327 mean for PISA math
and only 10% of the student sample was in Category-6 and they scored 401
In any good sampling system, 95% should be in category-6 and just 5% of student sample in Category 1
The PISA mean was 338, but for Hindi students answering PISA in Hindi, the score was 401
The gerrymandering artificially reduced score by 63
At 401, the math scores equal Orissa in TIMMS
The Real Indian IQ - G.Subramaniam - 02-25-2012
Errors in Indian PISA score - Part 4
---
The next area where gerrymandering has occurred is in over-weighting rural areas and in the urban areas, deliberately selecting bad schools
--
Among the school variables, the relevant factor is 'school community'
and is represented by question = SC04Q01
--
Category-1 = Village
Category-2 = Small Town
Category-3 = Town
Category-4 = City
Category-5 = Large City
--
I would normally expect the score to go up by 10, at each step, A 10 score is about 1.5 IQ
The reason is that as you get more urbanised, the schools get better, healthcare gets better, the percentage of upper-caste, higher IQ segment increases and other similar factors
--
In Himachal Pradesh,
67% of the sample is Category-1 or village with a mean math score of 329
15% of the sample is Category-2 or small town, with a mean score of 379
18% of the sample is Category-3 or town, with a mean score of 339
0% is Category-4
0% is Category-5
I smell a rat here.
First they have given 67% weighting to village and 0% weight to both City and Large City
Instead of seeing a rise of 10 points as we go from Category-2 to Category-3,
There is a drop of 40 points going from Small Town to Town
They must have searched for the worst slum school in Town
---
In Tamil Nadu,
44% is Village with mean math score of 332
9% is Small Town with score of 337 ( just a gain of 5 is fishy )
28% is Town with mean score of 366
12% is City with mean score of 386
7% is Large City with mean score of 376 ( A fishy loss of 10 instead of gain of 10 at this step )
Tamil Nadu is a highly urbanised state with Village and Small Town combined at about 25% of population
whereas this survey has given them 53% weightage
Also in TN, brahmins are heavily urbanised and most are in the large City category , which has been under weighted
--
In both states, with proper rural-urban weightages, I would expect scores to rise by about 20 or 3 IQ

Errors in Indian PISA score - Part 5
--
The next variable is School Variable = Public or Private School = SC02Q01
In India, the only kids who go to Public school are the starving kids who go for
mid day meal
Even the working poor send their kids to some sort of private school
--
HP
Govt School, Math score = 331, 85% of sample students
Private school = 379 , 15% of Sample students
--
TN
Govt School, Math Score = 334, 60% of sample students
Private School = 378, 40% of sample students
--
A minimum gain of 45 from switching to Private schools

Errors in Indian PISA score - Part 6

So what is the real Indian PISA Math score very conservatively
--
HP
Removing Linguistic minorities = 401
Removing Rural Bias = 20
Removing Govt School Bias = 20
Safety factor = -10
HP corrected Math score = 431
--
TN
Removing Linguistic Minorities = 378
Removing Rural Bias = 20
Removing Govt School Bias = 20
Safety Factor = -10
TN corrected Math Score = 408
--
Improvement beyond this will require better teaching curriculum, better nutrition, and more sampling of upper castes to get a correct idea of the Top end potential
The Real Indian IQ - G.Subramaniam - 02-25-2012
Errors in Indian PISA score - Part 7
--
So what is the real Indian PISA Math score realistic
--
HP
Removing Linguistic minorities = 401
Removing Rural Bias = 20
Removing Govt School Bias ( mid-day meal for starving ) = 45
HP corrected Math score = 466
Implied IQ = 100 - 15 x 0.34 = 95 IQ
--
TN
Removing Linguistic Minorities = 378
Removing Rural Bias = 20
Removing Govt School Bias ( mid-day meal for starving ) = 45
TN corrected Math Score = 443
Implied IQ = 100 - 57 x 15 = 91 IQ
--
Improvement beyond this will require better teaching curriculum, better nutrition, and more sampling of upper castes to get a correct idea of the Top end potential
The Real Indian IQ - G.Subramaniam - 02-26-2012
Calculating Average Indian IQ from PISA
TN raw math PISA score = 351
TN implied IQ = 100 - 1.5 x 15 = 78
HP raw math score = 338
HP implied IQ = 100 - 1.62 x 15 = 76
Indian Avg IQ based on raw PISA = 77
--
Next step is to remove the bias caused by the PISA sample having
75% bilingual kids
( Tibetan kids facing Hindi PISA exam and Telegu kids facing Tamil PISA exam )
TN mono-lingual = 378
Implied IQ = 500 - 1.22 x 15 = 82
HP mono-lingual = 401
Implied IQ = 500 - 15 = 85
--
Next there is a 40 point difference between scores for 'Village' and scores for 'Large city'
In HP and TN, The village category is over-represented by a factor of 4
Even worse, in HP, City and Large City are entirely removed from the survey sample
So adding an urban correction of 20 ( half the village-large city difference )
TN semi-urbanised mono-lingual = 378 + 20 = 398
Implied IQ = 85
HP semi-urbanised mono-lingual = 401 + 20 = 421
Implied IQ = 100 - 0.79 x 15 = 88
Current Indian IQ = 86
--
Next we look to the future as malnutrition is removed
The only Indian kids who go to govt school is for the mid-day meal,
If they are not starving they go to private school
Private schools score 45 more than govt schools and thats the future as poverty reduces
--
HP - future - semi-urbanised- mono-lingual = 401 + 20 + 45 = 466
Implied IQ = 95
TN - future - semi-urbanised - mono-lingual = 378 + 20 + 45 = 443
Implied IQ = 91
Future Indian IQ = 93
Given the huge bias in sampling towards over-representing the lower end IQ,
by the poverty pimp NGOs, I am certain that none of the CBSE or Cambridge schools
that serve the top 15% are included in the survey
And they have an entirely different IQ profile and cause an IQ bulge at the top end

ANNUAL OUTLOOK CFORE SURVEY
India's Best Schools
Total of 70 schools in 7 Indian cities surveyed
--
We shall look at schools which score more than 9.0 out of 10 in studies
The caste blend matters a lot more than school facilities
Chennai had 9 schools, 5 of which were SIB dominated
Delhi had 3 Schools, 1 of which was SIB dominated
Mumbai had 3 schools
Chandigarh had 1 school
Kolkata had 1 school
--
Delhi
-
Mothers International = 9.50 = Khatri ?
DPS RK Puram = 9.60 = SIB ??
Spring Dales, Daula Khan = 9.40 = Khatri ?
Incidentally DPS, Mathura Road = 8.10, vs 9.60 for DPS at RK.Puram, the only difference is caste blend
------
Mumbai
--
Scottish = 9.30
Cathedral = 9.20
Campion = 9.00

DAV Gopalapuram = 9.70, SIB
Don Bosco = 9.20
Padma Seshadri = 9.70, SIB
Vidya Mandir = 9.40 , SIB
Chettinad Vidyashram = 9.30, SIB
Church Park = 9.20
Good Shepherd = 9.10
Holy Angels = 9.10
Bharatiya Vidya Bhavan = 9.0 , SIB
The Real Indian IQ - G.Subramaniam - 02-28-2012
The interesting thing to note is that virtually all the non-chennai academic stars are convents
and this leads to psec phenomenon of deracinated Hindu elite
The only other place than Chennai to find a top performing Hindu school is Delhi
all 3 winners are Hindus schools
DAV network is around for 100 years, but only the Chennai DAV is an academic super star, due to SIB
Now I am going to go out on a limb. North Indians seem to love bling and pay fancy fees for fancy private schools
when the best academic school in the country is a DAV. Granted DAV-Gopalapuram is heavily Tambrahm, every other caste could benefit from DAV teaching methodology and DAV is fairly cheap in terms of school fees
In Chennai, around 1955, there was a Tam-brahm revolt against xtian convents,
And this led to formation of Vidya Mandir, Padma Seshadri, Bharatiya Vidya Bhavan, all academic star
Another interesting Chennai academic star is Chettinad Vidyashram
It is run by Chettiars, but teaches Hindu culture. It is located in a Tambrahm enclave and has
and entrance exam, which in itself skews the students towards Tambrams
Also lots of famous rich schools are missing from the list and are rip-offs

In curriculum quality , useful for handling PISA,
TN board = 1
CBSE = 9.5
ICSE = 14
Comparisons between ICSE and CBSE
ICSE provides a good overall development; the focus on literature is good. The CBSE concentrates more on Math and Science, which gives that slight edge for the engineering competitive exams.
ââ¬ÅIn ICSE projects on various subjects are an integral part. Also, thereââ¬â¢s a clear emphasis on English literature whereas in CBSE, English is functional, communication-based ââ¬Å says the Principal, Sri Kumaranââ¬â¢s Childrenââ¬â¢s Home. Kumaranââ¬â¢s offers ICSE and CBSE syllabuses to its students.
It is said that the ICSE syllabus is more extensive, and that the CBSE is more intensive. To elaborate, in the CBSE system of teaching, there are more objective kind of questions, which prepares students for national level competitive exams. ICSE is more liberal and gives a good choice of subjects. One can opt out of math and science in ICSE, not so in CBSE. The ICSE course develops thinking and analytical skills in a student because it is extensive.
The Real Indian IQ - G.Subramaniam - 03-01-2012
The main advantage of ICSE over CBSE is as follows
The ICSE is run mainly by the Anglo-Indians
So the syllabus has a lot more emphasis on English Language
ICSE is only for English Medium
To score well in PISA, you need language fluency,
which ICSE will provide in English
CBSE has a dual mode curriculum, both English medium and Hindi medium
So the English language syllabus is dumbed down in CBSE and this makes it harder to score
well in PISA
I would say that until 10th grade, ICSE is superior, whereas CBSE may be better for 11th and 12th
The Real Indian IQ - G.Subramaniam - 03-02-2012
The CBSE syllabus follows the concentric curriculum, where the topics taught are built on top of what was taught the year before last. For example, in Science, the topics motion, force, and pressure are presented in the 6th standard and the ideas of force, frictional force, and pressure are dealt with in more detail in the 8th standard.
The ICSE board follows the spiral curriculum approach. First the basic facts of a subject are learned, then more details are introduced. The basics are re-emphasised many times over to help get them into long-term memory. ââ¬ÅWhat the student studies this year is built on top of what was learnt the previous year,ââ¬Â says Nitya Ramaswami ââ¬â Head child development and Academics at the Zee schools
--
At least till 10th ICSE is far more rigorous
and all things being equal, ICSE will much score more in PISA than CBSE
The Real Indian IQ - G.Subramaniam - 03-02-2012
For 10th board exam
ICSE has 3 individual science papers = Physics, Chemistry, Biology
whereas CBSE has 1 combined science paper
Thats because CBSE at 10th is dumbed down to promote the lower iq masses
At 12th it is a different story, CBSE has a dedicated science stream and tightens the screws and catches up with ICSE

Several PISA like tests are being introduced in India, and most of the top-level schools are using them
--
What is common about these tests?
They stress on application of knowledge rather than knowledge per se.
Focus on reasoning, thinking, interpretation of data.
Standardised tests.
Objective, multiple choice
Offered in different subjects depending on the test (English, Math, Science, Computers.
Schools offer different tests. Some offer IAIS and some ASSET. Some kids enroll individually for these tests if the school does not offer them
These tests are made appropriate for the Indian context to some extent Many of these tests provide schools diagnostics and metrics about how students did in general and how to improve.
IAIS (International Assessment for Indian Schools)
AKA (also known as) Macmillan or University of South of Wales, Australia Test
http://iais.emacmillan.com/
Dates: Aug 28, 29 2009
Subjects English, Computer Science, Math, Science
Classes 3-12
One of the toughest tests in the spectrum
Asset testing
ASSESSMENT OF SCHOLASTIC SKILLS THROUGH EDUCATIONAL TESTING (ASSET)
http://www.ei-india.com/about-asset/how-do-i-prepare-for-asset/
Core Subjects: English, Maths and Science
Optional Subjects: Social Studies and Hindi
Based on the Indian curriculum (CBSE, ICSE and state boards)
Detailed Skill-wise feedback with customized letter for every student
Conducted in the school during school hours
Schools choose to take the test in Summer (July-August) or Winter (December)
Similar to IAIS. But supposed to be slightly easier.
Olympiads
http://www.silverzone.org/
Grade 1-12
Around Oct 6th
Our school offers only the Informatics Olympiad (computers + general reasoning).
But they offer Informatics, Science, English and Mathematics.
Relatively easy compared to IAIS.
Any other information??
Offered in most traditional Indian schools. CBSE schools.
