This study is not longer active, but remains on the OSHA website as a current example. 

The purpose of this study is to understand how speech-language pathologists acquire requisite knowledge and skills to assess and treat pediatric dysphagia, to identify requisite knowledge and skills that speech-language pathologists develop within graduate speech-language pathology programs, to identify requisite knowledge and skills that speech-language pathologists do not develop within graduate speech-language pathology programs, and to identify ways in which graduate speech-language pathology programs can better prepare speech-language pathologists to assess and treat pediatric dysphagia.
