The new Conners Continuous Performance Test (CPT-3), a test of visual attention, is available in the spring of 2014, with updated norms representative of students in the U.S., an additional testing paradigm that increases sensitivity to impulsivity, and a change in the test's structure of scores. The old Vigilance score is now the Sustained Attention score, and aspects of the Inattention score now make up the new Vigilance score. What I like about the new test is the increased sensitivity to determine if a student has ADHD. It has a companion test called the Conners Continuous Auditory Test of Attention (CATA). You can buy these separately, and each test takes 14 minutes to administer. The combined CPT-3 & CATA sensitivity has a correct diagnostic discrimination index of 0.92. What I don't like is that the norms now start at the age of 8 years, whereas the CPT-II norms started at age 6 years. There is a younger version (the K-CPT), but it is only good for children aged 4 to 5 years. There is a gap here in ages. It also uses T-scores instead of a probability of ADHD score as a percentage. I spoke with a technical support person from MHS who more recently said that the Kiddie version of the CPT is being revised to include children up to the age of 7 years.
