Six Keys for Accessible Online Course Development

Six Keys for Accessible Online Course Development

Digital accessibility in online education is no longer just a best practice—it is a fundamental ethical obligation, a cornerstone of equitable education, and, in many jurisdictions, a strict legal requirement. As educational institutions continue to rapidly expand their online course offerings, ensuring that these digital environments are accessible to all learners, including those with visual, auditory, cognitive, and physical disabilities, is absolutely paramount. Accessibility must be woven into the very fabric of the course development process rather than treated as a reactive afterthought.

However, many institutions struggle with how to implement and scale digital accessibility initiatives effectively across massive academic catalogs. The challenge lies in meeting complex federal legislations (such as Sections 504 and 508 of the Rehabilitation Act in the United States) and adhering to the Web Content Accessibility Guidelines (WCAG) 2.0 AA standards without causing significant disruptions to the course development cycle or incurring prohibitive costs. Developing accessible online learning environments is a complex endeavor that requires coordinated efforts, specialized knowledge, and a systemic approach to course design.

Based heavily on the strategic framework presented in Chapter 11 of the Guide to Digital Accessibility by Rae Mancilla, this comprehensive article delves into six strategic keys for accessible online course development. These keys offer a scalable, affordable, and practical blueprint for institutions looking to systematically dismantle barriers in their digital learning environments and foster a culture of inclusive excellence.

Key 1: Appointing a Senior Accessibility Instructional Designer (SAID)

The journey toward comprehensive digital accessibility often begins with a critical realization: when accessibility is deemed "everyone's responsibility" without clear, centralized leadership, it often becomes no one's responsibility. While instructional designers and faculty may undergo rigorous review processes for academic content, pedagogical rigor, and copyright compliance, accessibility can easily slip through the cracks without a dedicated expert at the helm.

Establishing Clear Accountability

To establish clear accountability and drive systemic change, institutions should appoint a Senior Accessibility Instructional Designer (SAID) or a comparable dedicated accessibility specialist. The SAID serves as the institutional compass for digital accessibility, providing a critical "accessibility lens" to all design decisions from the onset of course creation.

The Multifaceted Role of the SAID

The SAID’s responsibilities extend far beyond simple compliance checking. They act as the primary resource for answering complex accessibility questions from the broader instructional design team and the faculty. Their role involves overseeing the systematic review and remediation of course materials before these materials are finalized and integrated into the Learning Management System (LMS).

Furthermore, the SAID acts as a vital bridge across campus departments. They provide accessibility expertise for the entire campus by consulting on online course accessibility directly with faculty, and they collaborate heavily with the Office of Disability Services. This collaboration ensures that when students with specific accommodations register for a course, the SAID can expertly guide the retrofitting and remediation process, ensuring a seamless learning experience for the student.

Key 2: Developing Accessibility Training, Job Aids, Templates, and Tools

Proactive accessibility is always more efficient, less costly, and more effective than reactive remediation. To foster a culture of proactive accessibility design, the SAID must equip the instructional design team and the faculty with the knowledge, resources, and tools necessary to build accessible content independently from the ground up.

Comprehensive and Flexible Training Formats

Adult learners and busy faculty members require flexible professional development opportunities. Training should be offered in multiple formats: - Face-to-Face or Synchronous Workshops: Hands-on sessions where designers and faculty bring their own devices to actively practice making documents, presentations, images, and videos accessible. These workshops provide immediate feedback and foster a community of practice. - Asynchronous Online Modules: Self-paced courses embedded within general faculty development programs (such as an "Excellence in Online Teaching" course). These modules can cover best practices for universal design for learning and digital accessibility, serving as excellent just-in-time reference materials for faculty developing courses at their own pace.

Practical Job Aids and Boilerplate Language

Providing readily accessible job aids—such as clear, step-by-step guides for captioning videos, writing effective alternative text (alt text), or appropriately formatting accessible Word documents—empowers content creators to apply best practices independently. Furthermore, the SAID should provide standardized accessibility statements as boilerplate language for inclusion in all syllabi and LMS pages. This ensures clear, consistent communication regarding how students can request accommodations, such as: "If you require accommodations for tests, you are required to contact the Office of Disability Services to coordinate the accommodations prior to taking the test."

Standardized Templates and Automated Checkers

Pre-formatted templates (e.g., carefully designed, accessible PowerPoint and Word templates) establish a strong foundational baseline for faculty. While templates cannot prevent all accessibility barriers, they ensure that heading structures, reading orders, font choices, and color contrasts meet baseline standards right out of the gate. Additionally, disseminating knowledge about automated accessibility checkers—such as the built-in "Check Accessibility" feature in Microsoft Office products or external tools like TPGi’s Colour Contrast Analyser—enables creators to perform real-time audits during the authoring process.

Key 3: Consulting on Accessibility During the Course Development Process

Accessibility cannot be relegated to a final checklist at the end of the development phase; it must be an ongoing dialogue woven throughout the entire course development cycle. The SAID must establish an ongoing, proactive consulting relationship with the instructional design team and the faculty subject matter experts.

Vetting Third-Party Tools and Applications

Modern online courses frequently rely on a myriad of third-party applications, publisher web resources, and external interactive learning tools. Before integrating any external application (e.g., Pearson’s Smarthinking, interactive simulations, or virtual labs), it must be rigorously vetted for accessibility compliance. The SAID plays a crucial role in reviewing these tools, ensuring they do not introduce insurmountable barriers for students using assistive technologies like screen readers or keyboard-only navigation.

Collaborative Pedagogical Problem-Solving

Every academic course presents unique pedagogical challenges. When faculty design complex interactive assignments, visually rich discussions, or customized digital assessments, accessibility considerations must be integrated into the pedagogical strategy from day one. The SAID collaborates deeply with the design team to ensure that highly creative instructional strategies are matched with robust accessibility solutions. If an instructional tool is inherently inaccessible, the SAID works with the team to design equitable, alternative assignments that achieve the same learning objectives without excluding any learner.

Key 4: Procuring Third-Party Vendors, Student Assistants, and Interns

Given the immense scope of auditing, captioning, and remediating hundreds of courses annually, it is rarely feasible for a single SAID to shoulder the operational burden alone. Scaling digital accessibility initiatives requires strategic staffing, creative talent pipelines, and smart procurement strategies.

Leveraging Third-Party Vendors for Media Captioning

Multimedia accessibility, particularly accurate video captioning, is a highly resource-intensive endeavor. Leveraging third-party vendors for automatic speech recognition (ASR) provides a fast and highly cost-effective baseline. However, because ASR is not flawless (often carrying an error rate around 13%), the institution's accessibility team must perform stringent quality assurance spot-checks. If the ASR accuracy falls below acceptable standards, the institution must have workflows in place to resubmit the content for high-quality human captioning.

Empowering Student Accessibility Instructional Technology Assistants (SAITAs)

Employing student workers as SAITAs is a brilliant, cost-effective strategy that yields massive dual benefits: it significantly scales the institution's capacity to remediate documents while equipping students with highly valuable, marketable professional skills. Students can be trained using rigorous, free resources, such as those provided by the US Department of Homeland Security’s Office of Accessible Systems and Technology (OAST).

Once certified in authoring accessible Word, PowerPoint, Excel, and PDF documents, SAITAs can systematically remediate course materials under the supervision of senior designers. They learn to add alt text, create alternative formats, and write complex visual descriptions for media transcripts, gaining deep expertise in digital inclusion.

Fostering Talent Through Internships

Establishing formal, credit-bearing, or paid internships for students in Master’s programs for Instructional Design or Educational Technology further expands the accessibility team's capacity. Interns gain practical, remote-work experience in accessible course design, effectively allowing the institution to cultivate and train the next generation of accessibility-minded instructional designers.

Key 5: Checking and Remediating New Online Courses

Once a course has been drafted by faculty and instructional designers, it must undergo a comprehensive, meticulous accessibility audit before it is launched to students. This systematic check is typically conducted at the end of the development cycle, ensuring that all finalized content is scrutinized.

Systematic and Granular Review Methods

The remediation process must be highly methodical, addressing various distinct content types: - Video and Audio Files: All media must be accurately captioned. Crucially, non-verbal visual actions that are meaningful to the learning context (e.g., the specific steps of a science experiment shown visually without accompanying narration) must be textually described in a supplementary media transcript to provide equal access for students with visual disabilities. - Photosensitivity and Seizure Triggers: Videos must be rigorously audited for strobing, flickering, or flashing effects (specifically, anything flashing more than three times per second) that could trigger seizures or severe migraines in neurodivergent students or those with photosensitive epilepsy. Content violating this threshold must be edited. If replacement is impossible, explicit, prominently placed warnings are mandatory in the media transcript. - Student-Created Content: Accessibility standards must also apply to student-generated content to foster true peer-to-peer inclusion. Assignment prompts for student videos should instruct learners to verbally describe visual elements out loud and minimize flashing effects, ensuring all students can participate in peer discussions. - The PDF Challenge: PDFs are notoriously difficult for screen readers to parse correctly and highly time-consuming to remediate. A best practice is to hunt for original HTML versions of documents. If unavailable, inaccessible PDFs should be processed through Optical Character Recognition (OCR) software and converted into highly structured, accessible Word documents. - Images and Complex Graphics: All non-decorative images, infographics, and graphic organizers require appropriate alt text. For complex graphics where a short alt text is insufficient, extended textual descriptions (often provided as an alternative Word document) must be created to fully convey the complex relationships between visual concepts. - Interactives and LMS Content: Interactive elements like drag-and-drop activities are frequently inaccessible via standard keyboard navigation. In such cases, designers must create alternative, accessible versions of the interactive components. Finally, the native LMS pages themselves must be meticulously reviewed to ensure proper, nested heading structures, semantic HTML, and sufficient color contrast ratios.

Key 6: Checking and Remediating Legacy Online Courses

While newly designed courses benefit from the rigorous, proactive development framework outlined above, almost all institutions harbor a vast, sprawling catalog of legacy courses designed years before rigorous accessibility standards were codified and enforced.

Addressing the accessibility debt of legacy courses requires a prioritized, targeted, and highly responsive approach. The immediate institutional priority must be retrofitting legacy courses on-demand for students who actively register with the Office of Disability Services. This "just-in-time" remediation ensures that students facing immediate barriers receive fully accessible materials right when they need them, complying with legal accommodation mandates.

Furthermore, these rolling legacy audits provide vital data for continuous quality improvement across the institution. As legacy courses are systematically updated, taught over several semesters, and re-offered, they should undergo periodic re-auditing. This ensures that any incremental changes, new documents, or updated videos added by faculty over time have not inadvertently introduced new accessibility barriers. This continuous re-checking process safeguards the institution’s long-term digital accessibility integrity and prevents courses from regressing into inaccessibility.

Conclusion

Building a robust, scalable, and genuinely affordable digital accessibility infrastructure within a complex educational institution is a formidable but entirely achievable goal. By integrating accessibility checkpoints, training, and expertise into absolutely every stage of the online course lifecycle, institutions can move away from stressful, reactive, and panic-driven remediation toward a sustainable culture of proactive, inclusive excellence.

The six keys—appointing a dedicated accessibility leader, developing comprehensive training and toolkits, engaging in proactive design consultation, strategically leveraging vendors and student talent, and systematically auditing both new and legacy courses—provide a proven, actionable roadmap. Through the collaborative, interdisciplinary efforts of instructional design teams, disability services offices, dedicated faculty, and trained student workers, educational institutions can confidently meet stringent legal requirements. More importantly, they fulfill their most fundamental and profound ethical mission: providing high-quality, empowering, and completely barrier-free education to every single learner, regardless of their physical or cognitive abilities.
