This workbook is a companion to Mental Health Approaches to Intellectual/Developmental Disability: A Resource for Trainers and is designed to be given to all trainees. The Trainee Workbook contains copies of all slides that will be used in your training, but does not include text explaining the slides. The Trainee Workbook does include space for you to record your own notes about the material. Each training module includes a pre-test to be taken prior to the training and a post-test to be taken after the training. The Resource for Trainers and the Trainee Workbook provide training concerning the field of support for persons with intellectual or developmental disabilities (IDD) and mental health concerns.
