Learning Disability Evaluation Scale-Fourth Edition

Ages 8-16, Grades 2-11

The Learning Disability Evaluation Scale - Fourth Edition (LDES-4) is designed to provide a profile based on the most commonly accepted definition of learning disabilities (IDEIA, 2004). By relying on the observations of the classroom teacher or other instructional personnel, it documents those behaviors most characteristic of learning disabilities in children and youth in the areas of Listening, Thinking, Speaking, Reading, Writing, Spelling, and Mathematical Calculations. This feature makes the LDES-4 particularly appropriate for initial referral and screening procedures in which decisions for more thorough educational assessment must be made.

The LDES-4 standardization included 12 states, represented the major geographic regions of the United States, and approximated the demographic characteristics of the nation as reported in the Statistical Abstract of the United States (U.S. Census Bureau, 2010).

The technical manual includes data on internal consistency, test-retest, and inter-rater reliability; item and factor analysis; and content, criterion-related, diagnostic, and construct validity.
