Background Information on the AEM Quality Indicators

The purpose of the Quality Indicators and Critical Components is to assist state and local education agencies, institutions of higher education and workforce development agencies with planning, implementing, and evaluating dynamic, coordinated systems for the timely provision of accessible educational materials and accessible technologies. Given the variability of policies and practices across these organizations, the Quality Indicators and Critical Components are designed to provide agencies with consistent goals and to promote discussion around multiple methods to achieve those goals.

Foundational Principles

Several basic principles underlie the application of the Quality Indicators and Critical Components for the intended purpose of meeting an agency’s accessibility requirements.

  1. High level institutional or agency leadership is critical to the development and ongoing sustainment of the provision of accessible educational materials and accessible technologies.
  2. The Quality Indicators and their accompanying Critical Components are interdependent. No Quality Indicator is intended to stand on its own without the others.
  3. AEM implementation efforts, at all stages, require ongoing collaboration between the agency or institution and federal, state and local personnel, families and caregivers, other service agencies and individuals with disabilities.
  4. All AEM-related services and products developed and delivered by agencies are legally correct according to the mandates and expectations of federal and state statutes and regulations.


Since 2014 the National Center on Accessible Educational Materials for Learning (AEM Center) at CAST has had the responsibility to provide resources and technical assistance related to accessible materials and technologies to stakeholders in early learning, K-12 education, postsecondary education and workforce development. Building upon the prior work in the K-12 arena, the AEM Center expanded seven Quality Indicators to include foundational elements that can be used by agencies at all levels to guide development of effective, efficient systems for the timely provision of accessible printed and technology-based learning materials.

The Quality Indicators, which are brief statements that point to exemplifying conditions and services for high quality AEM implementation, are designed to assist with the implementation of statutory requirements that apply to state and local education agencies, institutions of higher education, and workforce preparation agencies. Relevant federal laws mandate that these stakeholders provide children, youth, and adults with disabilities equitable access to all learning materials, including printed materials, digital materials, and technologies. For state and local education agencies, this requirement is most prominently included in the Individuals with Disabilities Education Act (IDEA). Postsecondary institutions have similar mandates in the Americans with Disabilities Act (ADA) and Section 504 of the Rehabilitation Act (Section 504). Agencies in workforce development systems must attend to the mandates in Section 188 of the Workforce Investment Act/Workforce Innovation and Opportunity Act (WIA/WIOA). 

Critical Components of each Quality Indicator have been developed to provide actionable items that can be used to evaluate, improve or transform existing systems. These were determined by identifying best practices for implementing every aspect of the provision of accessible materials and technologies. Sources for the development of the Critical Components included research, policies, and expert guidance that have contributed to positive outcomes for related agencies and the individuals served.


The Quality Indicators and Critical Components are intended to be used across agencies in all stakeholder groups and by a wide range of personnel, individuals, and families. For example, at a systems level, leaders may use the Quality Indicators and Critical Components to update and improve policies for procuring accessible materials and technologies for system-wide use. At smaller scales, they may be used to develop guidance for selecting and creating accessible materials for curricular and programmatic use. Personnel at all levels may find them useful for determining and requesting sufficient resources for implementing accessible materials and technologies in varied settings, including classrooms, home, and the workplace. Users of the Quality Indicators may want to build background knowledge on any aspect of accessible educational materials and technologies by exploring this website further.
