Achievement, Aptitude and Diagnostic Tests
Captions available
The idea
Achievement tests measure what has been learned; diagnostic tests pinpoint specific strengths and weaknesses, such as word recognition, comprehension and fluency in reading; aptitude tests predict general achievement from verbal, quantitative and problem-solving skills.
In practice
A reading diagnostic shows fluent decoding but weak comprehension.
Where people slip
Intelligence tests are now often called cognitive ability tests, stressing developed rather than innate ability.
