A student’s CogAT profile is based on the pattern of scores from the administration of the three tests that are part of the CogAT (verbal, quantitative, non-verbal). How can we know if the verbal score is significantly higher than the quantitative score? All test scores have some error of measurement, so the difference should be larger than the error in either score. These profiles consist of A, B, C, and E and are provided for each of the three CogAT tests.
“A” Profiles. In an A profile, the student’s verbal, quantitative, and nonverbal scores are roughly at the sAme level. There is only one other piece of information provided by the test, and that is the overall height, or level, of the profile. This type of profile is what we would expect if reasoning ability were a single dimension. It is the pattern assumed whenever a student’s ability is summarized in a single score. About one-third of students obtain this profile.
“B” Profiles. In a B profile, one of the three battery scores is aBove or Below the other two scores. The student shows a relative strength (when one score is above the other two) or a relative weakness (when one score is below the other two). For example, B (V+) means that the scores show a B profile with a strength in verbal reasoning; B (N–) means a relative weakness on the Nonverbal Battery. Overall, approximately 40 percent of students obtain a B profile. Thus, B profiles are more common than A profiles.
“C” Profiles. This profile is called C for Contrast. The student shows a relative strength and a relative weakness. This pattern is much less common. About 14 percent of students have a C profile. A student who shows a relative strength on the Verbal Battery and a relative weakness on the Quantitative Battery would have a C (V+ Q–) profile. “E” Profiles. The B or C profile for some students is much more extreme than for others.
“E” Profiles. This profile is called the Extreme profile. Students with an E profile generally have significant differences 24 or more points on the SAS scale between their scores on two of the three tests.
