Intersurvey Consistency in NCES Private School Surveys. Working Paper Series.
Scheuren, Fritz; Li, Bonnie
This report provides empirical results of attempts to achieve consistency of estimates between two National Center for Education Statistics (NCES) surveys. These surveys are the 1991- 92 Private School Survey (PSS) and the Private School Component of the 1990-91 Schools and Staffing Survey (SASS). Consistency was sought in the numbers of schools, teachers, and students from these two sources. Comparisons are made among statistical and computational procedures that might serve to bring about the desired consistency. The complex nature of the survey designs is considered, and definitional problems are explored. Consequences of discrepancies and adjustments are discussed. The results of tests of nine typologies are presented. For some typologies (Catholic Parochial, Catholic Private, Conservative Christian, and Other Affiliated) the operational assessment shows the impact of adjustment on the SASS at least did no apparent harm, and an independent assessment shows that it might have been beneficial to accuracy. For three other typologies (Other Unaffiliated, Nonsectarian Regular, and Nonsectarian Special) the Generalized Least Squares (GLS) adjustment may have caused severe problems. Overall, results suggest that the use of a modified GLS reweighting, even when beneficial, does not make much of a positive difference beyond achieving consistency with PSS. Other methods appear needed to take advantage of the opportunity offered by having both surveys fielded for the same year. An appendix discusses a media GLS method.
