I received formal training on the use of the Tests of Variables of Attention (TOVA). I have received formal training in the use of various psychological assessments. This certificate acknowledges my attendance at a course on the Tests of Variables of Attention (TOVA), one of the most widely used continuous performance tests (CPTs). The course was conducted by Dr. Lawrence Greenberg, MD, the creator of the TOVA. CPTs are highly useful in the diagnosis of ADD/ADHD as the provide objective measures of impairment.
