This technical manual is designed to act as evaluation scales that will help evaluate and diagnose specific challenges young children, students and adults face. The manuals are designed to interpret data gleaned from the results of an administered rating form and are commensurate with criteria specific to the area in which the professional is working. These technical manuals can also be referred to as Evaluation Scales. In some cases, these manuals are available in a Home version and a School version (school version sold separately).
