The LCT-A:NU was normed on a stratified, nationally representative sample.
Administration and Scoring
Administration of the LCT-A:NU takes about 35-40 minutes. Raw scores are converted to scaled scores for the subtests and to a standard score for the total Listening Comprehension Index.
Reliability and Validity
- Cronbachs Alpha value was 0.94 for the Listening Comprehension Index.
- A Listening Comprehension Index cutoff score of 90 resulted in a sensitivity of 0.71, a specificity of 0.79, and a ROC/AUC of 0.82.
