Addressing the needs of our most diverse learners presents a tremendous opportunity with benefits for the entire education community. But teachers and administrators face common challenges: the burden of paperwork and data collection in service of a compliance culture, scarce time and resources, and a disparate understanding of how disability impacts learning.
ABOUT US
Our education systems are failing many of young learners with the most potential — students with disabilities. Research indicates that these students have the potential to graduate at rates approaching 90% or more, yet, today, only 65% graduate on time.
Too often, improvement efforts are incomplete — for example, focusing only on individual student progress or lengthy compliance exercises, or on assessing students by the same metrics used on their non-disabled peers. This fragmented process burdens already overworked teachers, feeding a cycle of low expectations and inconsistent instruction.
The Ability Challenge was launched as a non-profit organization in 2018 to help schools develop the systems and processes necessary to deliver world-class special education programming. We provide schools with tools to help close the gap between compliance and quality in order to help all students achieve.
