Data made available by means of a link provided with the Daily Planet article shows no consistent pattern of general increases or decreases in suspension rates until there occurredsubstantial decreases between 2012 and 2013 for all groups except Asians.[i]The 2012 and 2013 suspension rates for white, African Americans and Latinos (the principal groups of interest) are set out in Table 1.WithAfrican American’s and Latinos identified as the disadvantaged groups (DG), the table shows the ratio of the DG suspension rate to the white suspension rate and the ratio of the white rate of avoiding suspension to the DG rate of avoiding suspension.And we observe the common pattern whereby a general reduction in discipline rates led to an increase in the relative difference in suspension rates but a decrease in the relative difference in rates of avoiding discipline.The EES column indicates that, to the extent that the strength of the forces causing the rates to differ can be measured (see pages 15 to 23 of the Kansas Law paper), as to both African Americans and Hispanics, the difference increased very slightly (and did so in terms that would probably not be statistically significant).

[i] The Asian rate, which had been 1.0 percent, increased to 1.1 percent. The 10 percent change easily could be random variation. In any case, the interest here is with African American, Latinos and whites (though, because the Asian rate increased, all measures of differences between Asians and the groups whose rates declined would decrease).
