Generalizability Theory Analysis of CBM Maze Reliability in Third- Through Fifth-Grade Students

Abstract: Despite growing use of CBM Maze in universal screening and research, little information is available regarding the number of CBM Maze probes needed for reliable decisions. The current study extends existing research on the technical adequacy of CBM Maze by investigating the number of probes and assessment durations (1-3 min) needed for reliable relative (e.g., rank-ordering students) and absolute (e.g., comparing a specific score to a cutoff) decisions. Nine CBM Maze probes were administered to 272 students in… Show more

“…This variation in coefficients suggests that the reliability of one’s fluency score may be related to where that score falls in the population distribution. Other studies of standard error pertaining to fluency and growth in fluency (Christ & Silberglitt, 2007; Mercer et al, 2012) have converged on a similar result, namely, that the standard error of measurement is not static in a population.…”

“…When examining the number of CBM-R passages needed for universal screening, Mercer et al (2012) reported the number of necessary passages varies by grade level. Regarding decision-making for individual students, having multiple passages of performance is important to account for variability across passages (i.e., students perform differently on different passages).…”

“…Despite suggestions that maze selection is a more appropriate measure than CBM-R for universal screening for students in late elementary school (Jenkins & Jewell, 1993;Wayman et al, 2007), Wayman et al (2007) suggested more empirical evidence is needed to support this claim. Mercer et al (2012) recently extended research on the technical adequacy of maze selection by investigating the number of probes and assessment duration (1-3 min.) necessary for reliable decisions.…”
