Detailed explanation-1: -Predictive validity is the degree to which test scores accurately predict scores on a criterion measure. A conspicuous example is the degree to which college admissions test scores predict college grade point average (GPA).
Detailed explanation-2: -IQ scores can have predictive validity (e.g., performance in graduate school) without making any claims about the construct that is being measured (IQ tests measure whatever they measure and what they measure predicts important outcomes). However, IQ tests are often treated as measures of intelligence.
Detailed explanation-3: -Aptitude tests tend to be highly reliable, but they are weak predictors of success in life. However, their predictive validity for academic success in the early grades is fairly strong.
Detailed explanation-4: -An intelligence test is designed to understand ability. It does this by assessing critical thinking, learning abilities and so on. Thomas’ General Intelligence Assessment (GIA) measures an individual’s aptitude in 5 key areas: Reasoning, Perceptual Speed, Number Speed & Accuracy, Word Meaning and Spatial Visualisation.
