For example, we know that African-born immigrants surpass African Americans in attaining higher education, and it's possible that similar statistics exist for secondary education placement. The prominent think tank Migration Policy Institute devotes ongoing research to a specific Children of Black Immigrants Project. I'm sure they could procure demographics for the NYC public school system if you contacted them.<br /><br />>As for elite schools, proposals to expand the entry process beyond the meritocratic standardized exam and include school grades will probably backfire for African American students.<br /><br />>[Under] the broader criteria, many more girls would be admitted to the specialized schools — at Stuyvesant this year the gender gap is close to 600 students — and more white and Latino students would get offers to attend those schools, and fewer Asian kids would be admitted.

I am unable to find a source that makes a distinction between "native" and immigrant black students in SHS admissions, and doubt they exist. Clumsy as it may be, the ethnic selection box reads "Black or African American (including Africa and Caribbean)." Moreover, while blacks represent 26% of the student population in NYC, only 5% are offered admission (Hispanic 7%, White 28%, and Asian 52%). The NAACP has spearheaded legal action against admissions standards claiming violation of Title VI of the 1964 civil rights act (discrimination should be "inferred" from disparate exam scores). NYC's new progressive mayor is desperately trying to make school admissions more "fair" by eliminating the entrance exam. Whatever the future holds. I am astonished that the author makes such claims on an unidentifiable and minuscule sample size.

Currently, intelligence and scholastic tests on Africans show means in the 70-80 range, depending on sampling. However, that does not preclude finding some African version of the Ashkenazim, as you say. Currently no firm indications of such a group, but worth further search. The African Institute for Mathematical Sciences (in South Africa) should have some inkling of this, because they recruit the brightest African mathematicians. Years ago I suggested to Prof Neil Turok that he give a broad selection of intelligence tests to the selected candidates, but he did not take this up. I looked at the website about 2 years ago, and many of the candidates came from North Africa. It would be good to get more details on this. The site currently denies permission, but I think there must be accounts of where the students come from.Anonymoushttps://www.blogger.com/profile/09320614837348759094noreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-7790698159301586522015-07-09T13:57:16.134+01:002015-07-09T13:57:16.134+01:00Africa's a mighty big place, although you have...Africa's a mighty big place, although you have to see it on a globe to appreciate this.

However, this is not quite what we find. <br /><br />The score for mixed white & African children is nearly identical to the score for white children in both the GCSEs and the Cognitive Assessment Test (slightly higher in some years for the GCSEs), while the score for mixed white & Caribbean children is almost exactly the same as that for black Caribbean children in the GCSEs, but intermediate in the Cognitive Assessment Test (closer to the white British score than to the black Caribbean score, though).

It's the lowest "good" grade, based on the fact that institutions of higher education have widely used the C grade as a cut-off in their admissions requirements. (Lately, however, many universities are demanding B or better). The official lowest passing grade is a G. About 98% of pupils get a G or better. There is no grade that is officially called a "fail" grade. You can get an N (which stands for "Nearly), or a U (for "Unclassified").<br /><br />The distribution of grades shows a skew that suggests it has been carefully engineered to flatter the pupils with lots of A*, A and B grades. <br /><br />In the old O Levels, there were simple rules defining the percentage of pupils who get a given grade in any cohort. Today, there are no clear rules at all. It appears to be deliberately obscure.<br /><br />Re Black African and Black Caribbean demographics: the Black Caribbean group is rapidly disappearing, partly because some of that ancestry now prefer to identify as Black British, but more importantly because of the very high rate of exogamy. For years now, there have been more mixed White and Black Caribbean children born than plain old (vanilla?) Black Caribbean, and the rate is still rising. <br /><br />Black African exogamy is lower, but rising fairly quickly.<br /><br />As for the Black African population being apparently bimodal, I would hypothesize the following: prior to the 1990s, the Black African population in the UK was fairly small, and quite middle class. Visas were hard to get. You had to be well connected, rich, or eligible for a British passport. There was a population of Black Africans who were eligible because they (a) born in colonial times, (b) had come to Britain to study when it was easy to do so, and had stayed long enough to naturalize, or (c) were born in Britain to parents who were studying at British universities. There was a big drop in the number of African students studying in Britain after Commonwealth students were required to start paying fees at the foreign student rate. This happened under Margaret Thatcher, though I'm not sure of the year. <br /><br />The larger, more recent wave of immigration (since the late 1990) is less narrowly selected.<br /><br /><br />The more recent wave of melioristnoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-52897939924141624842015-07-07T22:17:01.693+01:002015-07-07T22:17:01.693+01:00Allow me to digress, onto the subject of GCSEs and...Allow me to digress, onto the subject of GCSEs and their precursors "O-levels".<br /><br />I did O-levels. For the top stream in my school the advice of the teachers was clear: these exams are below you. You may as well take them and you'll doubtless all do very well, but the exams come in May and by the preceding November-December we'll have finished the O-level syllabus and moved onto more interesting and advanced stuff. Perhaps not every pupil took this advice to heart as much as I did, but I admit that I sailed into the exams expecting figuratively to hit a few sixes without having spent much time in the nets or bothering to play myself in. <br /><br />Contrast this with my daughter and her GCSEs forty years later. In her school full of bright and very bright girls the exams were taken with great solemnity. The only critical words she uttered were to the effect that in her school it was the custom for the girls to do the continuous assessment component of the work themselves, whereas her chums at lesser schools assured her that much of the work submitted had been done by parents, tutors, or whomever.<br /><br />What a shambles: what a disgrace. What good reason is there for pupils with 140 IQs sitting the same exam papers as pupils with IQs of 84 or 94?
