Issues Regarding Samples and Settings Used in Validation
The process of validation asks, "Does the test measure what it is supposed to measure?" A test is not valid or invalid; statements of validity refer to the interpretations and uses of the assessment.
Applicable Scenario: Behind the Scenes of the Reading Lexile Framework
The assessment developers should clearly identify the population for which the assessment is intended, the construct (skill) it is intended to measure, how the scores will be employed, and the process by which the assessment will be given and scored.
As an English teacher, How do I know Lexile Measures are valid?
The population represented by the assessment sample should be throughly described. Relevant information, such as developmental level, community characteristics, and/or gender/ethnic demographics, should be shared in detail.
The validity of the Lexile Framework measures are evaluated by examining how well its measures relate to other constructs, such as reading comprehension (as measured by other assessments).
1. It measures what it says it measures: the semantic component and the syntactical component. 2. It has a positive correlation when compared to other constructs, like reading comprehension. 3. Scores are used to help guide appropriate reading materials. 4. The assessment is appropriate for independent samples: it is intuitive and widely recognized.
