Dyslexia Tools for the Classroom: What Works, What's Overhyped, and What's Free

Dyslexia is the most common learning difference in Australian classrooms, affecting somewhere between five and fifteen percent of students depending on which diagnostic criteria you use. Most classroom teachers will have at least one student with dyslexia in their class every year. Many will have four or five. And despite this, teacher training in dyslexia-specific instruction remains thin, in some programs, a single lecture module thin.

The tools gap this creates gets filled by the market, which is enthusiastic and not always well-calibrated. So before we talk about specific tools, one foundational point: dyslexia is a phonological processing difference. The most effective interventions target the specific deficit, systematic, structured phonics instruction, phonemic awareness training, and repeated practice with decoding. No app replaces this. The tools below support learning; they do not substitute for explicit instruction.

Text-to-speech: the highest-value access tool

Text-to-speech (TTS) technology allows students with dyslexia to access written content at their cognitive level, independent of their current decoding ability. A student whose reading accuracy is at year two level but whose comprehension, vocabulary, and reasoning are at year six level should not be receiving year two content. TTS removes the decoding bottleneck and allows the student to demonstrate what they actually know.

Speech-to-text: removing the writing bottleneck

Many students with dyslexia also struggle with written output, not because of a separate difficulty, but because the cognitive effort of spelling, letter formation, and monitoring their writing leaves little capacity for the thinking the writing is supposed to demonstrate. Speech-to-text allows them to compose by voice, which for many students produces dramatically better quality work.

Structured literacy tools and programs

These are the tools that support the explicit instruction work, phonics, phonemic awareness, decoding. They are most effective when used within a structured literacy approach, not as standalone gamified alternatives to instruction.

On dyslexia fonts: a note of caution

There are several fonts marketed specifically for dyslexia, most famously OpenDyslexic. The claim is that weighted letterforms reduce letter confusion and improve reading. The evidence for this is, at best, mixed. Studies consistently show that student preference for these fonts does not reliably correspond to improved reading accuracy or speed. Some students find them helpful; many don't. Make them available as an option rather than implementing them across the board, and let individual student response guide the decision.

Environmental and presentation adjustments that cost nothing

The most important thing

No tool changes a student's experience of themselves in the classroom as much as a teacher who understands what dyslexia is and what it isn't. A student with dyslexia is not a student with low intelligence. They are not lazy. They are not 'choosing' to avoid reading. They have a specific, neurological difference in how they process the written form of language. They often have real strengths that the written format is hiding.

When a teacher understands this, when they stop reading poor written output as evidence of poor thinking, the student's relationship with learning changes. That is the most powerful tool in this list, and it doesn't cost anything to install.
