For publishers of scientific journals, textbooks, research papers, and educational materials, accessibility compliance presents a unique challenge. While making standard text accessible is relatively straightforward, STEM content with its equations, data tables, scientific charts, and diagrams requires specialized expertise that most organizations lack internally.
The stakes are high. Educational institutions face legal mandates to provide accessible materials. Academic publishers must serve researchers with disabilities. Corporate training programs need compliant technical documentation. Yet mathematical notation, complex tables, and data visualizations resist standard accessibility remediation approaches.
This is where partnering with specialized accessibility services becomes essential. But not all providers understand the nuances of STEM content accessibility. Here’s what you need to know when outsourcing this critical work.
Why STEM Content Accessibility Is Fundamentally Different
Standard accessibility remediation adding alt text to photos, tagging headings, ensuring reading order follows predictable patterns. STEM content breaks these patterns completely.
Mathematical equations aren’t just images to describe. They’re functional expressions that screen reader users need to navigate, understand hierarchically, and sometimes manipulate. A simple quadratic formula contains nested structures, superscripts, fractions, and symbols that must remain mathematically accurate while being aurally comprehensible.
Data tables in scientific papers often span multiple pages with complex headers, merged cells, and nested relationships. A chemistry periodic table or statistical correlation matrix requires different navigation strategies than a simple spreadsheet.
Scientific charts and graphs present visual information that can’t simply be described in alt text. A scatter plot showing statistical significance, a phylogenetic tree, or a molecular structure diagram requires alternative representations that convey the same analytical insights not just what the image “looks like.”
What Exceptional STEM Accessibility Partners Deliver
MathML Expertise Beyond Basic Conversion: Anyone can convert LaTeX to MathML. Elite accessibility providers understand when to use presentation MathML versus content MathML, how to handle edge cases that converters miss, and how to test mathematical expressions with actual assistive technologies to ensure they read logically. They know that ∫ needs to read as “integral” not “strange S-shaped symbol.”
Table Remediation That Preserves Data Relationships: Complex scientific tables require sophisticated tagging strategies. Your publishing partner should understand scope attributes, header associations across multiple dimensions, and when to split impossibly complex tables into multiple accessible structures without losing data integrity or analytical meaning.
Multi-Modal Representation for Data Visualizations: The best publishing partner doesn’t just add descriptive alt text to charts. They create layered accessibility short alt text for context, longer descriptions for trends and patterns, and data tables that allow screen reader users to explore the underlying data themselves. Some even provide sonification options for certain data types.
Format-Appropriate Solutions for Mathematical Content: Different output formats demand different approaches. PDF/UA requires specific tagging for equations. EPUB3 leverages MathML with fallback images. HTML content might use MathJax or other rendering engines. Your accessibility services provider should master all these approaches and recommend the right solution for your publishing workflow.
Assistive Technology Testing with STEM-Specific Tools: Standard screen readers struggle with mathematical notation. Specialized tools like MathPlayer, ChromeVox, and NVDA’s math extensions interpret equations differently. Your partner should test across multiple assistive technologies to ensure mathematical content actually works in real-world scenarios.
The Questions That Separate STEM Accessibility Experts from Generalists
How Do You Determine When Complex Equations Need Simplified Alternatives?
Graduate-level mathematical proofs and advanced physics equations can overwhelm even sophisticated assistive technologies. Does your provider recognize when equations are too complex for purely auditory presentation? Can they work with subject matter experts to create conceptual alternatives that preserve mathematical meaning?
What’s Your Approach to Alt Text for Diagrams That Contain Both Visual and Analytical Information?
Consider a diagram showing electromagnetic wave propagation or a biological cell with labeled organelles. The visual layout matters, but so does the functional relationship between elements. How does your accessibility partner decide what information goes in alt text versus long descriptions? How do they structure descriptions so users can build accurate mental models?
How Do You Handle Tables Where Visual Layout Conveys Scientific Meaning?
Some scientific tables use spatial positioning, color coding, or visual clustering to communicate relationships that aren’t captured in the raw data. Think of taxonomic tables, comparison matrices, or experimental design layouts. How does your partner preserve these visual semantic cues for non-visual users?
What Validation Process Ensures Mathematical Accuracy Post-Remediation?
Accessibility remediation can introduce errors a misplaced parenthesis in MathML, an incorrect superscript, a reversed inequality. These aren’t just accessibility problems; they’re mathematical errors that could mislead students or researchers. Does your accessibility services provider have mathematically trained QA reviewers? Do they validate remediated equations against originals?
How Do You Make Interactive Scientific Content Accessible?
Modern STEM publishing increasingly includes interactive elements rotatable molecular models, adjustable graph parameters, simulation tools. How does your partner approach these? Can they create keyboard-accessible controls? Do they provide text-based alternatives that offer equivalent functionality?
What’s Your Strategy for Emerging Formats Like Jupyter Notebooks and Computational Documents?
Scientific publishing is evolving beyond static PDFs. Jupyter notebooks, R Markdown, and computational documents mix code, results, and narrative. How does your publishing partner approach accessibility for these hybrid formats? Can they remediate computational content while preserving reproducibility?
The Hidden Complexity: Domain Knowledge Matters
Here’s what many organizations discover too late: technical accessibility expertise isn’t enough for STEM content. Your remediation partner needs subject matter understanding.
A biology PhD can write meaningful alt text for a phylogenetic tree that captures evolutionary relationships, not just “a branching diagram.” A physicist understands which details in an apparatus diagram matter for comprehension versus which are purely illustrative. A mathematician recognizes when an equation’s visual layout carries semantic meaning that must be preserved in auditory presentation.
The best publishing partner either employs domain experts or maintains strong partnerships with subject matter consultants who ensure accessibility doesn’t compromise scientific accuracy or pedagogical effectiveness.

Choosing Your STEM Accessibility Partner
Outsourcing STEM content accessibility requires finding a publishing partner who combines technical expertise, domain knowledge, and genuine understanding of scientific communication. The wrong choice leads to content that’s nominally compliant but functionally inadequate equations that screen readers mangle, tables that confuse rather than clarify, diagrams with alt text so generic they’re meaningless.
