sponses for “Speaks another language at home,” “Language spoken,” and “English ability” items are very low.
We note that the amount of imputation over the period from 2005 to 2007 for all items has increased, which relates to the issue of response rate to surveys in general. The amount of imputation is also of concern because it introduces a variability that is not currently factored into the estimates of sampling errors from the ACS (National Research Council, 2007, p. 254).
CONCLUSION 2-5 Item nonresponse is a troublesome and growing issue for items used in the calculation of the number of English language learner children and youth.
