K-BIT 2 and CogAT
By Inderbir Kaur Sandhu, Ph.D
Q: Can you compare and contrast the purpose and interpretation of KBIT 2 and CogAT? Our daughter was 98th percentile on KBIT 2 in kindergarten. She is now going to take CogAT. Will CogAT in third grade measure the same skills/aptitudes or is the goal completely different. What should we expect? Thank you.
A: The Kaufman Brief Intelligence Test (KBIT Test) is a brief, individually administered measure of verbal (vocabulary subtest) and non-verbal (Matrices subtest) intelligence. The KBIT-2 test generates three scores: Verbal, Non Verbal and an overall IQ composite. Theoretically the verbal subtests measure crystallised ability and the non- verbal subtests measure fluid reasoning.
The Verbal portion of the KBIT-2 test is made up of two subtests, Verbal Knowledge and Riddles (takes between 15-30 minutes). These measure verbal, school related skills by measuring an individuals word knowledge, verbal concept formation, reasoning ability and range of general information. The Non Verbal portion is made up of the Matrices subtest and measures the ability to solve new problems by assessing ability to perceive relationships and complete visual analogies.
The Cognitive Abilities Test (CogAT) is a multiple choice test is used to measure cognitive development among children and is often used to identify gifted children for admissions into gifted and talented programs across the United States. The CogAT is administered to students in grades K-12 and the testing levels are divided by age group. This test assesses specific reasoning skills in areas that strongly correlate to academic success. The CogAT provides teachers and parents with information about students' cognitive development, ability to learn new tasks, and problem solving abilities. Additionally, several gifted and talented programs across the United States may require students to take the CogAT in order to be considered for admissions. Because much of its content is nonverbal, the CogAT is also very useful for testing students who are not native English speakers.
The main difference between the two tests is that the CogAT (administered in a group setting) is not an intelligence test; rather it measures reasoning abilities that are critical for success in school. K-BIT 2 (administered individually) is a brief measure of intelligence. Both the tests scores cannot be compared, as they are two different measures. Therefore, the goals of the two tests are very different as in achievement and intelligence. Hope that helps.
