In this evaluation Cate continues with the evaluation by performing an assessment of Alex’s speech and articulation through the use of an articulation screener from the PLS-5.Cate provides various levels of prompting and modeling throughout the evaluation. She sees that he is able to produce all sounds expected for his age, as well as almost all sounds he would need for English, when given a model/prompting. This demonstrates that articulation is not the issue causing intelligibility problems. Cate notes his productions of the same sound are variable, which leads her to consider developmental apraxia. As with previous modules, Cate indicates where this information should go in the final evaluation.
