Ethnic Differences in the UK


.pdf   R - 2015 secondary unvalidated summary report.pdf (Size: 8.03 MB / Downloads: 432)

I found some very new GCSE KS4 data. Do note though that the pass rates since 2014 are not comparable to previous years since they changed some rules to the sampling, excluding certain subjects and stuff like that. Also more students of certain groups are taking harder ebacc subjects now, namely blacks.

However this report contains average point scores per group and also ebacc attainment(the harder course) on page 41. Interestingly black Africans have higher average points score even though they have a slightly lower GCSE pass rate(since they take harder subjects on average) and also have higher overall ebacc attainment. Black Caribs and other blacks have a larger deficit in pass rate but their average point gaps are pretty close to whites and so is their ebacc attainment rate(since they take harder subjects on average). Both gaps for black Caribs and other blacks in GCSE average points are smaller than the one between white Brits and white Irish.

Mixed black and white Africans though are starting to open up a gap on whites in everything, ebacc attainment, average points and overall pass rate.

   

Sorry I don't know how to make the image larger. If you can edit it for me then please do.

We found some Wales PISA scores. There is a ~ 1 SD B/W gap there. Burge, B., & Lenkeit, J. (2015). Additional analysis of Wales’ performance in PISA 2012. Also, recent Dutch Cito scores show about a 0.6 SD Antilles/White Dutch Cito gap. I'll look for the link later.

So the real surprise is the high performance of Black Africans in the UK. But it's not such a surprise since I found more data confirming high performance in the US.

Check out the PIAAC scores of African born individual in the OECD: http://nces.ed.gov/surveys/international/ide/ They perform like Eastern Europeans. Hmmm.... so either (1) pretty selected or (2) heavy psychometric bias with respect to international IQ differences

Can that Dutch Antilles gap be considered a closure from the 0.75SD you mentioned here? https://z139.wordpress.com/2012/04/01/ho...black-gap/

A narrowing, no doubt.

right?
