The overall goal of this study is to learn about the neuropsychological (for example, thinking, learning, and remembering) and behavioral functioning of children being treated for cancer. Participants are being asked to take part in this research study because they have been diagnosed with cancer and because the cancer or the treatment that they are getting for that cancer might affect the function of their central nervous system, including the brain. This is also called neuropsychological function. This study specifically aims to utilize a standardized battery of age-appropriate neuropsychological and behavioral tests in conjunction with COG Phase III clinical trials to evaluate cognitive, social, emotional, and behavioral functioning over time. The primary aim of this study is to institute procedures to ensure a consistent, streamlined, and efficient administration of the neuropsychological/behavioral tests in a cooperative group setting in order to maximize compliance with a standardized assessment battery conducted at 3 standardized timepoints.
