The primary objectives of this research were to establish whether dynamic assessment could be implemented in children with hearing loss with a range of language abilities and to obtain pilot data to support the use of dynamic assessment for determining narrative language learning difficulties in children with hearing loss. Participants were three children aged seven to 12 years with moderate to profound hearing loss. The Test of Narrative Language (TNL) was used to measure narrative skills before and after two Mediated Learning Experience (MLE) sessions. Responsiveness to mediation in MLE sessions was compared to ability to learn based on a comparison of pre- versus post-test TNL scores. Two participants showed substantial improvements in their Oral Narrative subtest scores, and showed good responsiveness and modifiability in MLE sessions. One participant showed no change in TNL results, and low responsiveness and low modifiability in MLE sessions. Children with greater response to mediation had more improved TNL scores. Differential diagnosis of language learning difficulties in children with hearing loss may be possible using "dynamic assessment" (DA).
