EXHIBITOR SESSION: (HOUGHTON MIFFLIN)
Ability tests such as CogAT® are often used for high-stakes placement decisions in Gifted and Talented programs. These tests must provide both reliable measures of ability and be valid for the purposes of use. This session will address factors related to the reliability and validity of ability test scores such as:
- How long do I need to wait before retesting a student?
- When is an ability score too old to use?
- What effect does practice have on scores and score validity?
- Are certain types of ability scores – verbal, quantitative, or nonverbal – more predictive of student success and achievement?
- Is test score validity an issue in identifying ELL students?
Learner Outcomes:
- Understanding of the meaning of Validity as it relates to assessment for G & T
- Understanding best practices for the use of multiple measures in identification
- Understanding the role of "nonverbal" (or figural) assessment for ELL students
