Which CTOPP-2 subtest assesses rapid naming of digits?

• A. Blending Words
• B. Rapid Digit Naming
• C. Elision
• D. Sound Matching

Answer: (B)

Rapid naming of digits is all about how quickly someone can retrieve and articulate familiar digit names under time pressure. This subtest asks the individual to name digits as rapidly as possible as they appear, so it directly measures rapid naming speed and access to phonological information for digits. That focus on speeded retrieval sets it apart from the other tasks: blending words requires putting phonemes together to form a word, elision involves removing a phoneme from a word, and sound matching taps phonological awareness by comparing sounds rather than naming speed. Because the digits task targets rapid naming specifically, it best assesses rapid naming of digits.
