Rethinking Intellectual Developmental Disabilities: From Rigid Criteria to Responsive Practice

The criteria for identifying Intellectual Developmental Disability (IDD) have evolved, shifting toward more flexible and individualized assessment practices. Guidance from sources such as the AAIDD, DSM-5-TR, ICD-10, IDEA, and state regulations often varies, creating confusion for psychologists determining eligibility and planning supports. IQ thresholds and adaptive behavior criteria have moved from rigid cutoffs to more nuanced approaches, yet many states still use outdated or inconsistent standards. This skills-based workshop equips psychologists with tools to navigate these complexities through updated assessment strategies, strength-based report writing, and individualized transition planning. Participants will explore how to select and interpret appropriate measures, apply cultural and contextual considerations, and implement practical, affirming supports that promote inclusion, learning, and postsecondary success for individuals with IDD.

Course Objectives:

1. Identify and select appropriate assessment tools and techniques to determine eligibility for intellectual developmental disabilities (IDD).
2. Analyze the impact of cultural and contextual factors on the assessment and diagnosis of IDD. 
3. Utilize test data to develop strength-based, balanced reports that effectively communicate an individual’s abilities, support needs, and service recommendations. 
 4. Apply individualized support strategies to enhance educational and vocational outcomes for individuals with IDD
