Hearing Loss 

Hearing loss was originally defined in medical terms before the development of modern audiology. Today, professionals tend to use the consistent, research-based terminology of audiology. The following numerical values are based on the average of the hearing loss at three frequencies: 500 Hz, 1,000 Hz, and 2,000 Hz, in the better ear without amplification. The numerical values for the seven categories vary among professionals.

High Stakes Testing

Higher Level Language Disorder (HLLD) 

HLLD is a term which has found its way into the literature on communicative difficulties relatively recently. People described as having HLLD develop language which is structurally normal and have some understanding, but have problems with…

Often there is early language delay or disorder which seems largely to clear up, leaving the difficulties listed above. Many people with HLLD are of normal or above normal intelligence with good attainments in acquiring knowledge, solving problems and literacy. They often learn coping or masking strategies which hide their problems, and HLLD frequently does not show up on conventional language or psychological testing. Close observation and knowledge of the person is necessary for the diagnosis to be made, especially when checklists such as that above show such a degree of overlap with other contentious labels such as semantic-pragmatic disorder and Asperger’s Syndrome. People with HLLD often have difficulty with social skills and forming relationships with others. This, again, makes distinctions with other terms on the autistic “spectrum” hard to maintain confidently.
