I thought you might be interested in the Toronto School Board's parent census. They surveyed parents in Toronto and tied the results of the survey to the child's Grade 3 and Grade 6 standardised test performance. Basically no surprises here. Math performance goes something like this... East Asians, Whites, South Asians, Latin Americans, Blacks. Generalissimo Franco is still dead.
The funniest graph is Table 28 where parents answer whether the amount of homework assigned is just right, too little or too much. Most parents answer Just Right, and the rest are fairly evenly split, but the East Asian parents vote 38% to 2% for Too Little over Too Much. (There's no word on what East Asian children think about how much homework they're getting.)
