Rasch Rating Scale Analysis of Quality Indicators of Elementary and Secondary School Performance.
Schumacker, Randall E.
Types of quality indicators (QIs) for elementary schools and secondary schools in Texas, the selection of indicators by district superintendents in Texas, and the subsequent rating scale analysis using Rasch measurement procedures were studied. QIs were scaled from 1 to 7, with 1 representing "not important", and 7 representing "very important". Superintendents from 1,055 school districts in Texas received two separate 20-item QI rating scales for elementary schools and secondary schools. After a follow-up, the response rate was 71.5% (N=754). Results indicate that both the elementary school and secondary school rating scales were reliable. Item calibrations defined a continuum of important/not important variables, with item separation better defined for elementary school QIs as compared to secondary school QIs. The Rasch measurement model permitted comparisons of QI logits or standard scores (normal curve equivalents); consequently, it may have practical value for comparing similar schools. Eleven data tables and a 13-item list of references are included. An appendix provides descriptions of selected terms. (SLD)
