lead and through meaningful play with a caregiver, children begin to climb up the developmental ladder. Structure of the DIR Model and the Floortime Approach The DIR Model and the Floortime Approach work in two general parts: Assessment and Intervention. Within each of these two categories, there are further steps and strategies. Assessment The initial step for assessment is [Screening]. The creator of the DIR Model, Dr. Stanly Greenspan, developed a measuring tool, the Greenspan Social-Emotional Growth Chart (GSEGC), to aid parents, caregivers and clinicians in this beginning step of assessment. This tool is a basic 35-item questionnaire that evaluates a child according to the social-emotional milestones he or she has met. This preliminary step is a quick method to screen children for risk or diagnosis of Autism Spectrum Disorder (ASD) or Pervasive Developmental Disorder (PDD). Following the initial screening process is conducting a [Comprehensive Functional Developmental Evaluation]. A child that has been screened with the GSEGC and displays significant developmental delay will then proceed to this step. In this process, a single clinician or clinicians of multiple disciplines (i.e. pediatrics, speech therapy, occupational therapy, psychology, etc.) must spend a significant amount of time observing a child. Specifically, the clinician(s) must be able to characterize how the degree to which a child is able to interact with others as it relates to developmental level. In the final step of Assessment an [Individual Developmental Profile] is created based on the Comprehensive Functional Developmental Evaluation performed on the child. This profile is made to characterize a child's socio-emotional capacities. Through this profile, the DIR Model is able to tailor its intervention strategies uniquely to each child. Intervention Once the Assessment phase is completed the Intervention period is initiated. There are four different areas that the Floortime Approach aims its interventions: 1) Home 2) Educational Programs 3) Therapies 4) Play Dates. First, the strategies and exercises laid out in the Home Intervention are of great importance for a child. It involves three core interactions: floortime; semi-structured, problem-solving interactions; and motor, sensory, perpetual-motor, and visual-spatial physical activities. This home intervention, done primarily by the parents and family, is integral to the Floortime Approach. Second, interventions can also be applied through Educational Programs. Just as in the Home Interventions, the three core interactions are utilized in schools. Instead of primary caregivers carrying out these interactions it will be the responsibility of the teachers, teacher assistants,
