| Medical Model | -Appraisal -Diagnosis -identify etiology |
| Descriptive-developmental model | -describe the person |
| Systems | -What is their world like? -Who are they communicating with? |
| Identifying the cause | -to prevent the cause -if no clear cause, rule out what you know |
| Communication Assessment Process | -Referral -Case History, records, interview -Prelim description of functioning -Select Methods -Administer Assessment -Analyze results -Share info with client -Recommend or referrals -write Clinical Report |
| Areas of Assessment | -Hearing -Oral Mechanism _Language -Speech/Intelligibility -Voice -Resonance -Fluency -Swallowing/Feeding |
| Common Components to an Oral Mechanism Exam or Screening | -Structure (Face, lips, teeth, jaw, tongue, palates) -Function (Face, lips, teeth, jaw, tongue, palates) |
| Collateral Areas (additional) | -Cognitive Status(academics) -Social/Emotional(at home) -Motor functioning(clumsiness) -Vision |

| Informal Assessment Measures | -Interview -Observation -Speech/language/communication samples -Dynamic Assessment(test-teach-retest) |
| Standardized Testing | -structured -Goal:uniformity to reduce variations in test procedures across examiners and environments -Norms based on age -valid and reliable |
| Validity | -measures what its supposed to measure |
| Reliability | Consistency of results |
| Why Standardized tests? | -Useful for making comparisons -Helpful in identifying a deficit -Objective -Often required to qualify for services |
| Objective | not influenced by personal feelings |
| Subjective | influenced by a person's feelings |
| Peabody Picture Vocabulary Test-4 (PPVT-4) | -tests receptive vocab -norms for ages 2.5-90 -Administer items in a set |
| Basal | -Level of mastery -Starting point -may need to work backwards to establish basal -assume all previous items are correct |
| Ceiling | -Upper limits of ability |
| Cautions of standardized Tests | -Do Not use as only tool -Do Not use for setting intervention goals -Do Not use if not valid and reliable -Do Not use if standardization sample is not representative of person being tested. |
