In the final paragraph of the “Evolution in Grades and Test Results Over Time” section, the text “Thirty-one percent to 39% (depending on subject) of Level 1 students received a D or F grade. But perhaps surprisingly, 32% to 42% of these students received an A or B. This is an increase of 4 to 9 percentage points from the previous year” was incorrect. This should have read “Thirty percent to 32% (depending on subject) of Level 1 students received a D or F grade. But perhaps surprisingly, 40% to 42% of these students received an A or B. This is an increase of 2 to 13 percentage points from the previous year.”
Figure 3a initially reported that 12% of students receiving an achievement level 1 in math received an A in their math class, 20% received a B, 29% received a C, 14% received a D, and 25% received an F. Figure 3c initially reported that 14% of students receiving an achievement level 1 in science received an A in their science class, 21% received a B, 32% received a C, 15% received a D, and 18% received an F. The revised figures are shown below.
Figures 4a and 4c have been updated to reflect similar corrections.
