In 1999, an external review was conducted of the indicators and methodology that the National Center for Public Policy and Higher Education (NCHEMS) had developed for "Measuring UP 2000: The State-by-State Report Card for Higher Education." The principal purpose of these tests was to understand better the relationships among the indicators and between the indicators and the overall grades for each performance category. This document summarizes the kinds of tests conducted, the principal findings they generated, and the implications of these results for the performance findings in "Measuring Up 2000." A number of tests were conducted relative to data issues. These included: (1) tests related to missing data; (2) tests related to imputing missing values; (3) tests of the relationships among indicators in each category; and (4) statistical averaging over several years. Other tests were conducted to study methodological issues, including weighting, benchmarking, and cut-off scores. Other tests examined the relationships among graded categories, and additional tests were conducted of the relationships between preparation indicators and high school dropout, as well as those of the relationships between income gaps and increased income from having a bachelor's degree. The stability of performance indicators over time and controlling for demographic and background factors were also studied. Four appendixes contain additional details about correlational analyses, distributions, and tests of various measures. (Contains 37 graphs and 112 tables.) (SLD)
