Where did you get any source or any support that viet iq is 99 to 101. The pisa test does not say anything about IQ neither China included.

Note:
1. He cites most IQ studies out there on Vietnamese.
2. Malloy sometimes does a "
Flynn adjustment" wherein he will reduce an IQ test result by 2-3 points, or more. If you're familiar with the
Flynn Effect, you'll know why he does it. Malloy often gives a link or provides the study directly, so chase it down to get the original IQ score.
3.
He destroys Richard Lynn's scam: Lynn is notorious for cooking the books when the data does fit his "
East Asian > White > SE Asian > South Asian > Hispanic > Black" IQ based
caste system. That is, his racist fantasies. Lynn in particular always did this with Vietnamese: Everytime he encountered data where Vietnamese IQ was 110 or academic achievement was high he would say the subjects of the study were Chinese. Malloy actually tracks down both IQ and academic achievement studies where Vietnamese consistently outperformed Chinese Vietnamese, and finding
nothing in the opposite direction, where Hoa outperformed Kinh.
4.
"AQ" = IQ extrapolated from standardized tests, like
PISA, SAT, CAT. AQ is essentially
verbal IQ.
Visuospatial IQ tests are actually picture puzzles.
Verbal IQ is more important than
visuospatial IQ. (Jews have very high
verbal IQ and mediocre
visuospatial IQ. East Asians have high
visuospatio IQ and mediocre verbal IQ.)

As for China's IQ:
Analysis Of China’s PISA 2009 Results
The Chinese did not allow the OECD to publish data for the rest of the country and this understandably raised further questions about the situation in its interior heartlands,
The average PISA-converted IQ of the 12 provinces surveyed in PISA is 103.0.

I never believed China, a still developing country could match Japan and S. Korean in IQ. I knew it years before I came across this article in 2015.
In his 2002 book, "
IQ and the Wealth of Nations", race monger Richard Lynn claimed China had an IQ of 100, which was plausible despite China being so far behind the West and Japan at the time. Then in 2006 book,
"Race Differences in Intelligence", Lynn suddenly claimed China's IQ was 105, i.e. the same as Japan and South Korea a mere 4 years later. I never believed it. He was essentially cooking the books in favor of Chinese to fit his
East Asian > White hypothesis. Lynn wife is Chinese, IIRC.
Every country, group, etc., has IQ tests where the score is are 5-10 points higher or lower than the "average". The "average IQ" is accepted as "national IQ" for a group and is obtained from averaging all the known IQ test results. Not exactly scientific, but it is the accepted methodology.
Jason Malloy says he has found dozens upon dozens of IQ tests on Chinese in China which Lynn never mentions in his book, but Malloy doesn't read Chinese and is unable to assess them. I'm sure the averaging of all these scores would put Chinese IQ at well below 105. There are IQ test on Chinese in China that are in the 80's even. Having said that, I still think China's IQ is about where
PISA puts it, i.e. 103. But then again, what if
PISA was given to all Chinese, rather than just the official (Hong Kong and Shanghai) and hidden scores. Beijing only wanted to reveal scores for Hong Kong and Shanghai. Shanghai's scores were so high that the IQ equivalent was about 114, which makes me think it was given at only the more elite schools within Shanghai. And Shanghai is not representative of China to begin with.
About 7-8 years ago, an IQ test was administered in Vietnam and the score was about 101. Hanoi scored 106. Vietnamese netizens at the time said the high school where it was given was just an average school and not one of the elite ones. But then again, Hanoi is not representative of Vietnam to begin with. Yet had it been given at a Hanoi elite school, then the score would have been higher still--but even less valid since it would be even less representative.
Below concern PISA 2012, not 2009.
China is Cheating the World Student Rankings System
Enough is enough: Beijing must supply national data to assessors and not simply the results of a small minority of elite students
By David Stout

The OECD’s Program for International Student Assessment (PISA) exams are held every three years. Coming first and third respectively in the 2012 exams are the Chinese cities of Shanghai and Hong Kong.
Shanghainese and Hong Kong students are much better educated than those elsewhere in China. Slate quoted the Brookings Institution’s Tom Loveless as saying that “About 84 percent of Shanghai high school graduates go to college, compared to 24 percent nationally.” In addition, Loveless points out that affluent Shanghainese parents will spend large sums on extra tuition for the children — paying fees that far exceed what an average worker makes in a year.

Shanghai and Hong Kong are simply not representative, not unlike how Hanoi scored an IQ of 106 about 7-8 years ago. On the other hand, in PISA 2003, Vietnamese Australians outperformed Chinese Australians by a little, giving Vietnamese Australians IQ/AQ of 109.2 (Source: Jason Malloy, Human Varieties). The corresponding Chinese Australian PISA score had the IQ equivalent of about 107 or 108.
Hanoi is not representative of Vietnam, but Vietnamese Australians are children of "boat people", and actually are representative, albeit they live in first world conditions, which Vietnamese in Vietnam do not enjoy. Personally, I think the 2003 PISA score for Chinese Australians is representative since they are elite immigrants; but I think the 2003 PISA scores for Vietnamese Australians is an
outlier and a bit on the high side. Far more reliable is the Vietnamese American IQ/AQ of 104.9 extrapolated from the California Achievement Test. Vietnamese Americans are representative of Vietnam, but again, albeit they live in a first world country which Vietnam is not one. The point here is that overseas Vietnamese are "boat people" not elite immigrants like overseas Chinese, Japanese, Koreans, etc.
Further, the number of Vietnamese test takers for the CAT is probably in the 10's of thousands, where as in PISA 2003, the number of Vietnamese Australians was about 130 and similarly for Chinese Australians. Generally, 130 is more than enough for a sample size, but sampling errors can occur if the researchers are not careful.
