A recent LinkedIn post by educational psychologist Dr. Keith Houghton begins with a statement he credits to Dr. Muna Abdi: “It is not inclusion if you invite people into a space you are unwilling to change” (Houghton, 2026).
Dr. Houghton focuses on the classroom and the ways noise, lighting, expectations and other features of the environment can affect participation. His post raises a broader issue that extends beyond education: entering a space and being able to participate in what happens there are not always the same thing.
A student can enter a classroom and still be unable to follow what is happening there. A person with a disability may attend a public event but find no suitable place to sit. A visitor may enter a public building without knowing which route is accessible. The door may be open, but participation can remain uncertain.
The accessible route may be unclear, available seating may not meet the person’s needs, or important information may be difficult to read or hear. The individual may then need to find someone who can address the problem, delaying participation until the necessary changes are made.
Dr. Keith Houghton’s recent discussion of inclusion examines the effect of the classroom environment on learning. Noise can make it difficult for a student to distinguish the teacher’s voice from other sounds. Lighting and visual clutter can interfere with attention or make information harder to process. Inflexible expectations may create additional barriers. Houghton’s argument raises a broader question about what a person must do after entering a space before meaningful participation can begin.
Accessibility standards are an important part of the answer. In the United States, the Americans with Disabilities Act (ADA) Standards for Accessible Design establish requirements for the physical accessibility of buildings and facilities. These standards address how people with disabilities enter, move through, and use a facility.
One of those requirements involves the accessible route. An accessible route must connect certain arrival points, including accessible parking areas and public sidewalks, with an accessible entrance to the building. The route must meet specific accessibility requirements so that people with disabilities can reach the entrance without encountering physical barriers.
Doorways must provide sufficient clearance, and buildings must include enough space for a wheelchair user to turn in designated locations. Assembly areas must also provide wheelchair seating that meets applicable requirements (U.S. Department of Justice, 2010a).
These physical standards provide a necessary foundation, but they do not address every part of access. A person may enter a building without being able to participate in the program offered inside. Information may be unavailable in a format the person can understand, or a website or electronic form may prevent the person from completing a required step. A school may meet physical accessibility requirements while parts of the educational experience remain inaccessible.
A student may be able to enter a laboratory but remain unable to complete an exercise because the equipment or procedures do not account for the student’s disability. An after-school activity may present a similar problem when its location or format prevents the student from taking part. Programmatic access means that the student can participate in what the school offers, not only enter the building.
For public schools, these concerns are connected to the broader accessibility obligations of state and local governments. Title II of the Americans with Disabilities Act requires their services, programs and activities to be accessible to people with disabilities when considered as a whole. Public education falls within those requirements, along with other services provided by state and local governments (U.S. Department of Justice, 2010b).
The same principle applies beyond the classroom. A person may enter a public office but find that the application process does not accommodate their disability. A recreation program may take place in an accessible building while the activity itself remains unavailable to some participants. Physical access addresses whether a person can reach and enter the space, while programmatic access addresses whether the person can use the service or take part in the activity.
Participation also depends on communication. A person who is deaf may need a qualified sign language interpreter or captioning, depending on the situation. Someone who is blind may need Braille, an audio recording or an electronic document that works with screen-reading software. Large print may be appropriate for a person with low vision.
Braille continues to be an important reading and writing format for people who use it, although people who are blind or have low vision use a range of formats and access methods. These may include Braille, print or large print, speech output, and combinations of these approaches (Harris et al., 2023). Many people access digital information using screen-reading software, while some Braille readers use refreshable Braille displays (American Foundation for the Blind, 2023; Hoskin et al., 2024). The appropriate format depends on the individual and the nature of the information being communicated, including its length, complexity, and intended use (U.S. Department of Justice, 2014).
Access to programs and services also depends on digital systems. Students may need a website to register for a course or submit an assignment, while families often use school portals to receive information and complete required forms. Public agencies have also moved many services online. As access shifts to websites and mobile applications, accessibility standards help determine whether people with disabilities can use those resources.
The Web Content Accessibility Guidelines (WCAG), developed by the World Wide Web Consortium, are intended to make websites and other digital content more accessible to people with disabilities. The guidelines address how people access and use information online. They consider whether a person can read the content and navigate a website. They also address whether website features can be used and whether the content works with assistive technology, including screen readers (World Wide Web Consortium, n.d.). WCAG organizes these requirements into three levels that reflect different degrees of accessibility..
The Web Content Accessibility Guidelines (WCAG) organize accessibility requirements into three levels: A, AA and AAA. Each level builds on the one before it. Level A addresses barriers that can prevent someone from accessing or using digital content. Examples include providing text alternatives for images, making functions available by keyboard and providing captions for prerecorded video (World Wide Web Consortium, n.d.).
Level AA adds requirements that improve accessibility for a broader range of users. These include sufficient color contrast, allowing text to be enlarged without losing content or function, and using consistent navigation and labels. Color contrast refers to the visual difference between text or other important content and its background so that the content is easier to see and read (World Wide Web Consortium, n.d.).
Level AAA includes additional requirements intended to provide an even higher level of accessibility. Examples include stronger color-contrast requirements, sign language interpretation for prerecorded video and additional support for understanding complex content (World Wide Web Consortium, n.d.).
In 2024, the U.S. Department of Justice adopted new accessibility requirements for state and local government websites and mobile applications. The requirements are based on the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA. They apply under Title II of the Americans with Disabilities Act.
The compliance deadline depends on the size and type of government entity. State and local governments serving 50,000 or more people must comply by April 26, 2027. Those serving fewer than 50,000 people, as well as special district governments, must comply by April 26, 2028. Special district governments are public entities created to provide specific services, such as public transportation, water, or other local services.
The rule includes limited exceptions for certain types of content, including archived material, some older electronic documents, content posted by unaffiliated third parties, certain password-protected individual records, and social media posts published before the applicable compliance deadline (U.S. Department of Justice, 2024, 2026).
The importance of Level AA is not limited to technical compliance. It is also about whether people can use a website or mobile application to get information, complete a task, or take part in a government program or service.
A student should be able to register for a course without an inaccessible form getting in the way. A person using a screen reader should be able to identify a button and submit an application. Someone who is deaf or hard of hearing should be able to follow information presented in a video.
Level AA gives state and local governments a consistent way to address many common digital barriers. It does not address every situation or account for every accessibility need. The standard provides a clearer basis for reviewing digital content and making changes that support more consistent access.
Physical, programmatic, communication and digital access cannot be treated as interchangeable. An accessible entrance does not correct an inaccessible registration form. Wheelchair seating does not make an uncaptioned presentation understandable. A compliant doorway does not ensure that a student receives an approved accommodation. A fuller approach considers the setting, the program being offered, the way information is communicated and whether the technology can be used by people with disabilities.
Written policies do not ensure access if they are not followed consistently. A student may have an approved accommodation for extended test time, yet still have to explain it to each instructor before an examination. An event organizer may not recognize a seating barrier until an attendee points it out; a public program may provide essential information in a document that assistive technology cannot read.
The same problem can arise when the barrier is part of the setting itself rather than a written policy or formal accommodation. Noise, lighting, and other features of a classroom can affect how a student is able to follow instruction and complete work.
A student may miss part of a lesson when several people are talking or chairs scrape across the floor. Glare from overhead lighting can make written instructions harder to read. If the student completes less work or appears distracted, adults may focus on concentration or behavior without considering whether noise, lighting, or another feature of the classroom contributed to the difficulty.
Even with careful planning, not every barrier can be anticipated or addressed in advance. Individual planning will sometimes be necessary because people have different needs, and some physical limitations may take time to correct. Older buildings can present particular challenges. Schools must work within existing facilities and available budgets, and public agencies face many of the same constraints.
These constraints can affect how quickly a change is made, but they do not eliminate every opportunity to improve access. An organization can identify known barriers and provide accurate information about them, even when a physical renovation must wait. Procedures may also be revised without altering the building itself. Replacing an entrance, for example, is very different from clearly identifying which entrance is accessible. Each involves a different level of effort, time, and expense.
Providing clear information is one practical place to begin. An organization can identify accessible entrances, explain how to request an accommodation, and provide a consistent contact who understands the process. Accurate information allows people to know what to expect before they arrive.
Schools can use the same approach in the classroom by providing written instructions with spoken directions and examining environmental features that may interfere with participation. Unnecessary noise, lighting, visual clutter, and seating arrangements can be considered separately rather than treated as a single problem. These changes will not address every barrier, but they can reduce the number of arrangements students must request and negotiate on their own.
The distinction becomes important when access depends primarily on individual exceptions. An exception is a change made after one person encounters a barrier and asks for a different arrangement. The person may then have to explain the barrier and its effect before someone with authority approves a response.
Formal documentation may be appropriate for an individual accommodation, but some practical options can be available without requiring a diagnosis or a separate approval process. Informal arrangements can also become unreliable when an employee is absent or a new staff member is unaware of what was previously agreed. A consistent procedure is more likely to remain in place when schedules, personnel, or circumstances change.
Even a well-designed procedure may miss problems that become clear only when people use a space or service. A student can explain when classroom noise interferes with instruction. A wheelchair user may find that a route meets technical requirements but is still difficult to navigate. A person with low vision can point to glare or poor signage that makes moving through a building more difficult. These are details that may not be obvious from a policy, plan, or floor plan. When a change is made to address a barrier, the person affected can also help determine whether it actually works.
Dr. Houghton’s post offers a useful starting point for thinking about what inclusion looks like beyond initial access. No setting will work the same way for everyone, and there is rarely a single response that addresses every need. Schools, public agencies, and other organizations can consider where barriers continue to arise, listen to the people affected, and make reasonable adjustments where appropriate.
Formal access requirements provide an important foundation, but they do not always capture how a classroom, event, service, or website is experienced in practice. There can still be a difference between having access and being able to participate fully.
Perhaps there is also room to consider what access looks like once the formal requirements are met. Those requirements provide an important foundation, but they do not always show how well access works in practice. Participation may still depend on what happens beyond the formal requirements.
