CELF-3^UK is the most powerful and comprehensive diagnostic language tool which measures a broad range of expressive and receptive skills in children and adolescents. The following subtests are included: 

• Sentence Structure 

• Word Structure 

• Concepts and Directions 

• Formulated Sentences 

• Word Classes 

• Recalling Sentences 

• Sentence Assembly 

• Semantic Relationships 

• Word Associations 

• Listening to Paragraphs 

• Rapid Automatic Naming. 

Raw subtest or composite scores for the 3 core receptive and 3 core expressive tests are converted into standard scores with selected confidence intervals, percentile ranks and age equivalents. Two supplementary tests are available for both the younger and older age groups. 

Features of the CELF-3^UK 

• UK norms collected on a national representative sample 

• UK adaptation of items and illustrations 

• Full colour stimuli 

• Extended age range 

• Easily understood format for CELF-R users 

• Core receptive and expressive plus supplementary subtests 

• Extensive reliability and validity data 

• Detailed extension testing procedures 

Can I upgrade from the CELF-RUK? 

No, the CELF-3^UK is a new edition of the test - old items have been dropped, new items and sub tests added; the stimulus materials have been altered with the introduction of colour and, for the first time, full UK normative data is provided. 

CELF-PreschoolUK and CELF-3^UK: UK Standardisation Studies 

Dr Ian Peers (Department of Communication Sciences, University of Sheffield) and Dr Peter Lloyd (Department of Psychology, University of Manchester) directed the UK project for both tests. Daily management was undertaken by Miss Caroline Foster, Research Assistant. 

The standardisation sample for both tests is representative of the UK population for the appropriate age ranges (3 to 7 years, and 6 to 16 years). The data collection project was one of the most comprehensive ever undertaken in the field of language development in the UK. The respective sample sizes of 588 and 568, coupled with the extensive US data and the long history of development of the CELF measures, provides the clinician with extremely reliable and valid diagnostic language tools. 

Each sample has been stratified according to age, gender, socioeconomic status, ethnicity and geographic region. 

Examiners were recruited to cover all UK regions. Extensive training, feedback to examiners and quality control procedures ensure that the UK normative data is of the highest quality. 

Extensive validity data, correlations with other language and cognitive measures, detailed psychometric data ensure that both clinicians and researchers can make the fullest use of the comprehensive results obtained from using the CELF-PreschoolUK and CELF-3^UK
