Why do language samples?
• Standardized assessments often are not
sensitive enough to address specific needs of
children who are DHH
• Quick, functional, more “real life” examples
Language samples
• Measure productivity and complexity/quality
of language
• Simple language samples can work
• Key Components
– Over time
– Across communication domains
Across communication domains
• Phonology
• Morphology
• Syntax
• Semantics
• Pragmatics
Clinical decision making
• Intervention services
• Interprofessional communication
• Parent support/advocacy
CLINICAL DECISION MAKING:
QUALIFICATION, GOALS
Case Study: Time 1
• Walk
• He running
• In school scream
• No
• Yes
• Watching
• Be quiet
• Hearing
• Car
• Take turn with car
• Stop
• Me
• Matt glue
(King, Olson, Shaver & Blaiser, 2009)
Case Study: Time 2
• Who gave you the clip?
• Grandma is walking inside.
• I go to a baseball game.
• A lot of little kid go to the baseball game.
• Lucy didn’t go to the baseball game.
• Lucy go to the football game
• That’s a monster.
• You gotta little monster and I got a big monster.
• Where Erika R at?
• Maybe she go to the bumper car.
• Why no field trip?
• He is getting bigger. He growing up.
(King, Olson, Shaver & Blaiser, 2009)
INTERPROFESSIONAL
COLLABORATION
What are the errors?
• The car go in the garage
• He going to the hospital
• He going back to the hospital over here
• He have to go up to a parking spot
• He going back home now up the road
• He will go back up to the (unintelligible) and the he want to go back home
• he going to see the window
• Oh no! the car fall down.
• He will go back and try again
• He try to use the elevator
• He going back home because he want to play

Language Sample 2
• Did the other group have four friends here? • Do you know what, Sarah? I was sick September 20th. • My birthday’s coming up. How can I get to be five? • I went to Chuckie Cheese’s a long time ago but one of my friends
came, Eric but another friend didn’t come because he was not invited.
• Do you know what? Tomorrow on Tuesday I’m going to take my day off.
• Even, you know what? My dad was at work and I told him about the T-rex dinosaurs.
• My dinosaur name is Sarah ‘cuz I like that name. • Why we have to cut a hole in the dinosaur’s mouth?• Black is my favorite color because so you can see better and I’m
wearing black strip shirt today.• You know, there was a nice shark at Mall of America. • Can you hear it Matt? It’s liquid. • I like ketchup with French fries but not other food.

SHARING OUTCOMES WITH OTHERS
Family Support
• Communicate progress of speech/language targets achieved in therapy.
• Describe present performance of:– Intelligibility
– Mean Length of Utterance (MLU)
– Words per minute (WPM)
– Number of total words
– Number of different words
– Number of complete sentences with correct syntax and word order
– Variety of syntactic elements used
– Phonological processes observed
Family Support
Place: Therapy Context: Retelling story w/forest animals, looking at book Amount of time observed: 15 min total recorded
CURRENT MONTH: May 2013
It should be noted that the therapist is very familiar with XX’s articulation and was able to benefit from a shared attention of objects. Intelligibility may have been lower to a less familiar listener and without contextual clues during the conversation.

Family Support
• Discuss impact of rate of speech (WPM) compared to:
– MLU
– Intelligibility
– Number of complete sentences with correct syntax and word order
– Is there an inverse relationship? Fluency vs Accuracy?
– What implications are there for parents to target at home?
Family Support
• Compare Number of Total Words vs.
Number of Different Words
– Implications for vocabulary development
– Appropriate variety of syntactic elements
Family Support
• Measuring progress:
– IEP goals
– TASL
– CASLLS
• Age appropriate progress
– Chronological Age
– Hearing Age
Family Support
• Compare success of speech/language targets
achieved across school and home
environments
• Explain targets to be stabilized in therapy
• Determine targets to be reinforced at home
• Negotiate with mainstream school and related
services
Graduate training
• Plan appropriate activities to provide
opportunities to elicit language targets in
context
• Support transcription process
• Establish clear rules for
reporting/analyzing/interpreting results

Graduate Training
This sample was taken on client XX on May 7,
2014 in the context of conversation about his
Kindergarten, as well as his favorite movie. XX
was not very talkative throughout the sample,
and the clinician had to probe considerably to
keep XX engaged in the conversation.
Accordingly, this sample is not as spontaneous
as others have been in the past.

Graduate TrainingXX's utterances were shorter overall, which contributed to a slightly
decreased mean length of utterance, as well as a significant decrease in his number of words spoken per minute. However, he was more intelligible than in past samples, and his utterances were also more syntactically correct. This data can be interpreted to mean that there is an inverse correlation between XX's rate of speech, and his overall intelligibility and accuracy of syntax.
XX demonstrated some instances of whole word repetitions and word finding errors throughout the sample. He tended to use repetitive phrases for emphasis (e.g. "a lot a lot"), in the place of more descriptive vocabulary terms.
XX's voice was quite harsh, and he demonstrated more instances of whispered speech than in the recent past. Furthermore, he did not demonstrate effective self-monitoring of his saliva. These issues can possibly be attributed to the fact that XX may have been coming down with a cold, as he frequently coughed throughout the sample as well.
Substitutions are coded in blue, distortions are coded in green, and deletions are coded in red. Selections coded in purple represent whispered speech.
Graduate Training
• Clinical decisions
– Evaluate success of past intervention strategies
• Predict scaffolding needed in future
– Determine targets to be addressed in therapy
– Identify targets to be reinforced at home and in other school settings
– Referral for related services
• Professional reporting/discussing
• Collaborate with supervisor, parents, other professionals
