How do we qualify and work with a bilingual population when:
▫ The tests we use are not normed on this population.
▫ My gut feeling doesn’t match the test results.
▫ I don’t know what goals are appropriate.

Learner Objectives • Participants will list, identify, describe…▫ Reasons for testing both languages▫ Formal and informal measures for testing ELLs▫ Use of tests when a student is not represented in the
normative sample▫ ASHA guidelines for assessment with bilingual
students▫ Red flags for speech and language impairment in
bilingual children.▫ Sounds on the Goldman-Fristoe that are subject to
second language influence

• We need a standardized score• However, the formal tests have not been normed
on our populations
• We rely on informal assessment• We use formal testing as a way to gather
information

• It’s always critical to use information beyond the assessment tool to complete an assessment.
• Let’s look now at some of the things that can help us differentiate bilinguals with typical development from those with delayed/disordered language skills.

• Difficulty learning both languages, even with adult assistance
• Family history of language/learning disabilities • Slower development than siblings• Difficulty interacting with peers• Inappropriate pragmatic/social language skills (i.e.,
turn-taking, topic maintenance, considering listener needs, non-verbal communication)
• Difficulty with language in many routines• Idiosyncratic error patterns • Language performance unlike others with similar
cultural/linguistic experiences

A student from a second language home does not perform typically for her age on standardized and informal evaluations.
Is this due to second language influence or is she truly impaired?
![Page 23: Evaluating Students From Culturally and Linguistically Diverse Populations: Determining difference from disorder](https://reader031.vdocuments.us/reader031/viewer/2022030317/546b092caf795919088b471c/html5/thumbnails/23.jpg)
When do we test in two languages?
• Is the language survey valuable to us?
• Are the results from language proficiency testing valuable to us (Woodcock-Muñoz Language Survey)?
Speech and Language Testing is Cumulative not Comparative
![Page 24: Evaluating Students From Culturally and Linguistically Diverse Populations: Determining difference from disorder](https://reader031.vdocuments.us/reader031/viewer/2022030317/546b092caf795919088b471c/html5/thumbnails/24.jpg)
Cumulative not ComparativeLanguage and Content of Intervention Select based on what is appropriate in each language and
what is appropriate for child’s and family’s situation. For example:
Spanish•Gender•Verbs•Article+nouns•Food •Clothing•Household items
Both•People•Functions•Categorization•Part-Whole
English•Pronouns•Prepositions•Nouns•Colors•Numbers•Shapes

Assessment Summary
• So what do we know?▫ Not all bilinguals are the same ▫ Children learning a second language may display
behaviors common in monolinguals with language impairment
▫ Problems associated with all assessment tools▫ We need to go beyond the tool in assessment▫ Ongoing assessment across many daily routines is
critical▫ Exploring all languages is essential

A word on DNQs
•DO NOT QUIT here!
• You put 60 days of work into this student and know him better than anyone at this point
• Share the data to explain how to support the student and make him successful in the classroom

Questions:
• Is it possible that his language scores are "flat" due to being bilingual?
• Should I have an Arabic assessment done? If so, how should I go about it?
• Or since he isn't LEP, should we go ahead and qualify him as SI?

• Results▫ Assessment completed with Arabic interpreter▫ Language sample with much longer and more
complex utterances than demonstrated in English▫ Minimal vocabulary errors▫ Minimal syntax errors▫ Fully intelligible to interpreter

Case Study #3BRITISH ENGLISH /HEARING IMPAIRMENT
• Mild to moderate hearing impairment • 50% Intelligible• 1st Percentile with standardized speech testing• 69% intelligible during 100 word sample• Family from England and has been living in the
United States for two years
![Page 42: Evaluating Students From Culturally and Linguistically Diverse Populations: Determining difference from disorder](https://reader031.vdocuments.us/reader031/viewer/2022030317/546b092caf795919088b471c/html5/thumbnails/42.jpg)
Questions:
• How do we figure out what is causing the low intelligibility? Is it a true speech impairment, resulting from the hearing impairment, or influence from British English?
• Can the norms from the standardized test be used because he speaks “English?”
• If he qualifies, how do we determine appropriate goals?

• Outcome▫ Parents more thoroughly interviewed. This
was a dialectical difference in the area they came from
▫ SLP researched (“googled”) specific dialect to identify attributes
▫ Speech errors were put up against Typical errors with hearing impairment Age-appropriate errors in SA English Dialectal differences of “Brummie English”
▫ Results follow

Take Away Points• Thorough language history is critical.• Thorough health (especially hearing) history is
needed.• Testing in all languages is the only way to get a
complete picture of a student’s abilities• Understanding the features of the non-English
language as well as how those compare to English will help identify what errors may be due to cross-linguistic influence.

Difference or Disorder? Understanding Speech and Language Patterns in Culturally and Linguistically
Diverse Students
Rapidly identify speech‐language patterns related to second language acquisition to distinguish difference from disorder.
