Overview

Instrument Name: Clinical Evaluation of Language Fundamentals (CELF) - Fifth Edition - English for the USA

Abbreviation: CELF-5

Points for Consideration:

This is the most widely used clinical tool for children with TD who are older than 3 years; also very extensively used in research. The benefits are that it parses out grammar from other areas and has specific receptive/expressive composite scores. The negatives are that many of the subtests have very heavy working memory loads which can impact the performance of many individuals with DD. Given its wide use, it would serve as a strong comparison with other studies, but it's unlikely to see movement on this measure. Large normed population, good longevity (use the CELF-preschool then the CELF-5) since the tests span 3yrs-21 yrs. This would allow tracking over time for children that need to be followed for years to establish durability of tx (gene therapy).

Description of Tool:

The Clinical Evaluation of Language Fundamentals (CELF) - Fifth Edition - English for the USA is a ClinRO, ObsRO, and PerfO developed to assess a student’s language and communication skills in a variety of contexts, determine the presence of a language disorder, describe the nature of the language disorder, and plan for intervention or treatment in children aged 5:0-21:11 years (all therapeutic indications).

Mode of Administration:

Data Collection Mode:

Time for Completion: Core Language Score: 30-45 min Total assessment: variable

Response Scales: Dichotomous 4-point Likert/Likert-type Scale Other: Tasks, Checklist

Summary of Scoring:

Available scores:
- Scores by domains: Individual test raw scores are converted into normalized scale scores based on a mean of 10 and a standard deviation (SD) of 3
- Composite scores: Core Language Score (CLS); Receptive Language Index (RLI); Expressive Language Index (ELI); Language Content Index (LCI); Language Structure Index (LSI); Language Memory Index (LMI). Composite raw scores are converted into normalized scale scores based a mean of 100 and a standard deviation (SD) of 3

Weighting: No information

Sore Direction: Higher score = Better performance
