The National Household Education Survey (NHES) was conducted for the first time in 1991 as a way to collect data on the early childhood education experiences of young children and participation in adult education. Because the NHES methodology is relatively new, field tests were necessary. A large field test of approximately 15,000 households was conducted during the fall of 1989 to examine several methodological issues. This report focuses on measurement errors arising from the use of proxy respondents. During the 1989 Field Test, a knowledgeable household member was used as a source of information on the school enrollment of each sampled 14- to 21-year-old in the household. In addition, this age group was asked to report on its own school enrollment. The correspondence between the responses given by proxy respondents and the youths themselves is reviewed. Field test findings indicate that it will be possible to estimate the size of measurement error associated with using proxy respondents, but that it may be prudent to collect data from a household member and from the youths themselves to improve the reliability of dropout estimates. Fourteen tables and two figures illustrate the discussion, and an appendix contains statistics on the measurement errors for variables used to derive event and state dropout rates. (SLD)
