Archive: 2008 CUT SCORES for R-CBM
Revised 9/09 Use of Cut Scores: Cut Scores for the ISAT are intended to be used primarily for Program Evaluation purposes (for example making triangles). Scores at-or below values of below basic indicate justification for concern; Scores at or above the proficient level indicate a high probability that students have mastered basic skills for that grade level. Scores in the confidently proficient range are characterized by a .5 probability of exceeding standards (and empricially resulted in fewer than 2% not meeting standards). Scores that fall between the Below Basic and proficient range indicate a degree of uncertainty regarding mastery of basic skills. Stability: Performance of cut scores across years and districts has been stable +/- 10% including revised ISAT 05-06, 06-07 and 07-08 for grade 3. Cut-scores are approximated with a combination of logistic regression and discriminant function analysis with the criterion measure being the state test for Illinois (ISAT). Bootstrap resampling of 100 repeated logistic regressions of third grade data revealed asymmetric 95% empirical confidence intervals within 4 WRC. Specifically, the Fall cut score for Below Basic of 51 ranged from 51 to 54 WRC; The Fall Proficient Cut Score of 77 ranged from 76 to 80. Validity. Predictive Validity coefficients for R-CBM to ISAT ranged from .71 to .74, with a sample of between 1300 to 2600 students from 8 districts in Northern Illinois. Removed Measures. Repeated failure to replicate adequate diagnostic indices has caused me to remove cut scores for Initial Sounds Fluency, Phoneme Segmentation Fluency and MAZE. While these measures may be useful as diagnostic screeners, or convergent sources of data, my analyses do not support the use of these measures without the support of other more reliable and valid measures of General Outcomes in Reading.
