Do you have reliability data that you used to “test” the LD Screening Tool? And/or how have you validated it?March 10th, 2009

I have informally validated the Learning Difficulty/Disability Pre-Screening Tool and Informal Comprehensive Identification Tool over my 35+ years of assessing students by the correlation of it to the following formal testing that was done with my students:
Woodcock Johnson III
Woodcock Reading Diagnostic Battery
Developmental Optometrist’s Testing Reports
Occupational Therapist’s Assessment Reports
Gibson Cognitive Test Battery (GCTB)
Woodcock Reading Mastery Test (WRMT)
Learning Efficiency Test (LET-II)
Test of Language Development-Primary (TOLD-P:3)
Clinical Evaluation of Language Fundamentals (CELF-4)
I have also had a variety of parents use the informal assessment tool for their kids who later had formal testing done which confirmed the results of the informal assessment tool.
Additionally, I have used research & resources from:
