Chapter 1 Eligibility Factors and Weights: Using Probit Analysis To Determine Eligibility Criteria.
Willis, John A.
Kanawha County (West Virginia) schools use Z-scores to identify elementary students eligible for Chapter 1 services in reading and mathematics. A probit analysis of over 500 previously served students was used to determine the variables and weights in the Z-score equations. Independent variables were chosen from those commonly used to identify Chapter 1 students. The best predictor formula for reading services used student's age, Comprehensive Test of Basic Skills (CTBS) total reading (or MRT reading composite) normal curve equivalent (NCE) score, end-of-year letter grade in reading, and number of times a student had been retained. For mathematics, best prediction was obtained with CTBS total mathematics (or MRT) NCE scores, end-of-year grade in mathematics, and grade level of the student. Additional formulas were developed to account for missing scores and grades. Using these formulas, initial eligibility lists are developed in the summer and given to Chapter 1 project teachers, who modify and update them throughout the year. Problems and advantages of the method are noted, and some examples of use of Z-scores for other purposes are given. Three tables present Z-score information. Attachments include eligibility lists, forms to amend the lists, and a report using Z-scores in an evaluation of the Reading Recovery Program in the county. (Author/SLD)
