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

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
