Socioeconomic status (SES) affects cultural perspective and speech and language development and can be found in testing materials and the evaluator’s interpretation of assessment performance.
Reliability is the degree of consistency of measurement in a test. A test has a high degree of reliability if it produces similar results consistently under similar conditions.
It is important to be as thorough as possible when writing the background section of the evaluation as extenuating circumstances could explain a delay in language development and also help the evaluator differentiate between a delay, disorder, or normal language development, given the circumstances.
The standard error of measure indicates the amount of uncertainty that a sample (such as a normative sample) is truly representative of the general population. In the case of administering standardized tests, it conveys the level of uncertainty that a single test performance observed by the evaluator represents how the child would do if it were administered multiple times.
Bias occurs when one interprets or judges others based on their own background and experience and it can result in viewing other practices, expectations and perceptions as inferior or wrong and can result in many different consequences.
Dynamic Assessment is a method of assessment which uses a “test-teach-retest” model and the emphasis is on the individual’s ability to acquire the skills/knowledge being tested after being exposed to instruction.
