Murphy, Daniel L.; Beretvas, S. Natasha – Applied Measurement in Education, 2015
This study examines the use of cross-classified random effects models (CCrem) and cross-classified multiple membership random effects models (CCMMrem) to model rater bias and estimate teacher effectiveness. Effect estimates are compared using CTT versus item response theory (IRT) scaling methods and three models (i.e., conventional multilevel…

Petscher, Yaacov; Foorman, Barbara R.; Truckenmiller, Adrea J. – Journal of Research on Educational Effectiveness, 2017
The objective of the present study was to evaluate the extent to which students who took a computer adaptive test of reading comprehension accounting for testlet effects were administered fewer passages and had a more precise estimate of their reading comprehension ability compared to students in the control condition. A randomized controlled…

Dadey, Nathan; Briggs, Derek C. – Practical Assessment, Research & Evaluation, 2012
A vertical scale, in principle, provides a common metric across tests with differing difficulties (e.g., spanning multiple grades) so that statements of "absolute" growth can be made. This paper compares 16 states' 2007-2008 effect size growth trends on vertically scaled reading and math assessments across grades 3 to 8. Two patterns…

Shermis, Mark D.; Long, Susanne K. – Journal of Psychoeducational Assessment, 2009
This study investigated the convergent and discriminant validity of the high-stakes Florida Comprehensive Assessment Test (FCAT) in both reading and writing at grade levels 4, 8, and 10. The data from the 2006 FCAT administration were analyzed via traditional multitrait-multimethod (MTMM) analysis to identify the factor structure and structural…
