Low-Incidence Disability

A disability that occurs relatively rarely in the general population, such as blindness, deafblindness, or certain developmental conditions. Low-incidence disabilities present unique challenges for research, education, and technology development because affected individuals are geographically dispersed, making large-scale studies difficult and traditional quantitative evaluation methods less applicable. Educational technologies and curricula for low-incidence populations must be highly adaptable to accommodate the significant diversity within these small groups, and efficacy measures often need to emphasize qualitative, individualized indicators of success rather than standardized assessments.
