The Learning Disability Evaluation Scale - Renormed Second Edition (LDES-R2) was developed to enable instructional personnel to document those performance behaviors most characteristic of learning disabilities in children and youth. The LDES-R2 avoids the nature of a testing situation by relying on the performance o bservations of the classroom teacher or other instructional personnel. The instrument is designed to provide a profile based on the most commonly accepted definition of learning disabilities (IDEA, 2004). This profile classifies whether the student’s difficulties are in the areas of Listening, Thinking, Speaking, Reading, Writing, Spelling, or Mathematical Calculations. This feature makes the LDES-R2 particularly appropriate for initial referral and screening procedures in which decisions for more thorough educational assessment must be made.
The LDES-R2 standardization included 25 states, represented the major geographic regions of the United States, and approximated the demographic characteristics of the nation as reported in the 2000 Statistical Abstract of the United States.
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.
Characteristics and Components of the LDES-R2
-
The LDES-R2 is based on the federal definition of learning disabilities (IDEA, 2004).
-
The LDES-R2 was standardized on a total of 4,473 students, including students with disabilities.
-
The LDES-R2 was factor analyzed to create the seven factor clusters (subscales).
-
The LDES-R2 includes norms for students ages 6 through 18 years and grades 1-12.
|
-
Subscale standard scores, quotients, and percentiles are provided by gender, age, and grade placement.
-
The LDES-R2 includes 88 items representing the most commonly identified characteristics of learning disabled students and can be completed in approximately 20 minutes by instructional personnel.
-
The Pre-Referral Learning Problem Checklist provides a means of calling attention to the behavior for the purpose of early intervention before formal assessment of the student.
-
 The Learning Disability Intervention Manual (258 pages, © 2007) contains goals and objectives for the student’s IEP, as well as a complete set of interventions/instructional strategies for the 88 specific learning problems identified by the LDES-R2. The computer program provides an individualized printout of goals, objectives, and specific interventions chosen for each student’s unique learning disability.
-
The Parent’s Guide to Learning Disabilities (200 pages, © 1991) was written for parents to help their learning disabled child experience more success at home and at school. A variety of intervention strategies are presented for each learning problem so that parents can choose interventions which best suit their child and their home environment.
-
The LDES-R2 Quick Score computer program converts raw scores to standard and percentile scores and makes the scoring of the rating form efficient and convenient.
