Accessible E-Learning Design: Standards, Principles and Best Practices

Today, more than 1.3 billion people worldwide live with some form of visual, hearing, motor, or cognitive disability. Designing accessible e-learning is not just an ethical issue: it is a legal, strategic, and business imperative for any organisation that trains its people.

In this article you will find the principles, standards, and best practices you need to create truly inclusive e-learning — without sacrificing quality or return on investment.

DEI Strategies: 3 Key Business Benefits

More and more companies are embedding accessibility into their Diversity, Equity and Inclusion (DEI) strategies — a set of practices and policies designed to ensure equal opportunities for everyone in the organisation, regardless of ability, background, or identity.

The data strongly supports this approach:

Economic profitability

According to the Getting to Equal: The Disability Inclusion Advantage report by Accenture, companies with advanced inclusion practices generate up to 28% more revenue and 30% higher profit margins than their competitors. Accessibility also extends the reach of training programmes to the entire workforce, reducing the need for costly individual adaptations.

Talent retention

An accessible learning environment is a direct signal of inclusive culture. According to McKinsey, the most diverse and inclusive companies are 35% more likely to outperform their competitors. Furthermore, 57% of people look for companies that champion diversity when choosing where to work.

Reputation improvement

A joint study by the ONCE Foundation and Reputation Institute concluded that including people with disabilities has a direct and positive impact on corporate reputation. Organisations perceived as inclusive build greater trust among clients, investors, and prospective talent.

Why Is It Important to Create Inclusive E-Learning Courses?

Digital corporate training can reproduce the same barriers that exist in the physical world if it is not designed with accessibility criteria in mind. An employee with a visual impairment who cannot read the instructions of a course, or a person with hearing difficulties watching a training video without subtitles, is receiving an inequitable experience that limits their professional development.

Beyond equity, there is also a clear legal framework. In the European Union, the European Accessibility Act (EAA) sets binding requirements for digital products and services, including e-learning platforms. Organisations that train employees with disabilities must treat these standards as a reference for best practice and compliance with applicable regulations.

The conclusion is clear: designing accessible e-learning is not just doing the right thing — it also protects the organisation, ensures regulatory compliance, and extends the impact of training to the entire workforce. Developing soft skills and digital competencies in an inclusive way is a genuine competitive advantage.

Universal Design for Learning (UDL) Principles in E-Learning

Universal Design for Learning (UDL) is the international framework for creating accessible learning experiences from the outset — not as a later adaptation. Developed by CAST (Center for Applied Special Technology), it is based on three core principles:

• Multiple means of representation: offering information in different formats (text, audio, video, infographics) so that each person can access content in the way that best suits their abilities.
• Multiple means of action and expression: allowing learners to demonstrate their knowledge in different ways — written, oral, visual — rather than forcing a single format.
• Multiple means of engagement: designing content that motivates different learner profiles, offering options for difficulty, pace, and degree of autonomy.

Applying UDL in practice means not adding subtitles as an afterthought in production, but planning them from the script; not adjusting font size as a patch, but establishing an accessible typographic hierarchy from the template.

WCAG 2.2 Standards: What an Instructional Designer Needs to Know

The Web Content Accessibility Guidelines (WCAG 2.2) are the international standard for digital accessibility. Although originally designed for websites, their four principles — known as POUR — apply directly to e-learning content design:

• Perceivable: all information must be available to the user’s senses. In practice: alternative text on images, subtitles on videos, audio transcripts, minimum colour contrast of 4.5:1.
• Operable: the interface must be usable with a keyboard, without requiring precise mouse movements. In e-learning: keyboard navigation between screens, no arbitrary time limits on quizzes.
• Understandable: language must be clear and the interface predictable. In practice: explicit instructions, descriptive button labels, clear error messages.
• Robust: content must work with assistive technologies (screen readers, magnifiers). This means using correct semantic HTML or accessible SCORM structures in the authoring tool.

Instructional designers do not need to be WCAG technical experts; what is necessary is that the authoring tool they use incorporates these criteria natively so that exported content meets them automatically.

Main Challenges When Designing Inclusive E-Learning Courses

Knowing the benefits of accessible e-learning is only the first step. In reality, many L&D teams encounter concrete barriers when implementing it. Here are the three most common:

1. Understanding accessibility standards and legislation

Accessibility regulations can be complex: WCAG 2.2, ATAG 2.0, EN 301 549, the European Accessibility Act, Directive (EU) 2016/2102… For a training team without a specialist technical profile, knowing which standards apply in each case and how to translate them into course design is a real challenge. If you want to explore the technical standards in more depth, we recommend this article on e-learning accessibility, where we cover the technical requirements in detail.

2. Technical difficulties when creating accessible courses

Many authoring tools do not generate SCORM content with the required accessibility structure: they do not correctly label interactive elements, do not export with keyboard navigation, or do not allow alternative text to be added to all objects. The result is that instructional designers have to choose between creating accessible content or creating visually engaging content — when they should be able to do both.

3. Maintaining training ROI

A common obstacle is the perception that designing accessibly increases production costs or slows things down. In reality, when the authoring tool incorporates accessibility as part of the standard workflow — not as a layer added afterwards — the additional effort is minimal and the return is maximised: the entire workforce is reached, individual adaptations are reduced, and compliance is achieved from the very first version of the course.

Types of Disability and Design Solutions in E-Learning

A practical way to apply UDL and WCAG principles is to think about the four main disability groups and what specific design decisions address each one:

Overcoming Accessible E-Learning Challenges with the Right Authoring Tool

Most of the obstacles described above share a common denominator: they depend largely on the authoring tool used by the L&D team. Not all tools create accessible content in the same way, and choosing the right one can make the difference between a project that meets standards from the start and one that requires costly revisions afterwards.

5 Criteria to Evaluate Whether an Authoring Tool Is Truly Accessible

1. Accessible SCORM export: the exported package must maintain ARIA labels, correct heading hierarchy, and semantic roles on interactive elements.
2. Full keyboard navigation: all screens, buttons, and activities must be navigable without a mouse, both in the editor and in the published course.
3. Alt text for every element: there must be an alt text field for every image, icon, and visual element directly in the editor, without needing to edit the exported HTML.
4. Integrated subtitles and transcripts: the tool must allow subtitles to be added or imported directly within video and audio components, not as an external element.
5. Controllable contrast and typography: the tool’s templates and themes must include palettes that meet WCAG 2.2 contrast ratios by default, or allow real-time verification.
