CORE has various subtests that cover different cognitive domains. However, it is not necessary to take every subtest and users can take the subtests they are interested in. There are three recommended composites for CORE:
- Abbreviated Battery A quick battery which can provide a moderately accurate full-scale score within 30 minutes. This composite includes AG, FW, and DS.
- Optimized Battery This battery is close in accuracy and reliability to the Full Battery but your specific Index scores will be less reliable. However, it will require less than 2 hours of testing and can be spaced out over multiple sessions. This composite includes AG, MR, FW, GM, VP, SA, QK, DS.
- Full Battery This battery includes every subtest and is the most accurate and most reliable measure of your Full Scale IQ and index scores. The downside is that this will take approximately 3 hours of testing, but it can be spaced out over multiple sessions.
Disclaimer: CORE is intended for native English speakers. Non-native speakers may experience reduced accuracy in the Verbal Comprehension Index. Future updates aim to enhance accessibility for non-native speakers through language-specific VCI subtests. It is recommended for non-native speakers to refer to their CFI (Culture Fair Index) score or avoid the Verbal Comprehension subtests.
