Clinical evaluation of language functions (CELF) diagnostic battery: an analysis and critique

To summarize, the main strengths of the CELF are the clarity with which the manual describes the subtests and the instructions provided for test administration. Major concerns center on the absence of a theoretical framework as a basis for the selection of language skills assessed, the use of only "normal" children in the standardization sample, the lack of scoring criteria for one subtest, the seemingly incorrect weighting system for another, and minimal evidence of test reliability and validity.
