Stark Griffin™ (SGDA) Dyslexia Adult English Assessment Full Kit

Stark Griffin™ (SGDA) Dyslexia Adult English Assessment Full Kit

The Stark Griffin™ Dyslexia Adult English Full Kit helps professionals assess, diagnose, and subtype dyslexia in adults with accuracy and confidence. Many adults reach university or the workplace without a diagnosis, so this kit offers clear answers. It identifies the presence and severity of the three recognised Stark Griffin subtypes—Dysnemkinesia, Dysphonesia, and Dyseidesia—and gives a full cognitive profile that guides effective support.

Only registered SGDA-trained practitioners may use this kit. The tools align with the academy’s evidence-based diagnostic protocols and work well in private practices, universities, adult learning centres, and workplace support settings.

Why Assess Dyslexia in Adults?

Many adults still struggle with reading and writing but never receive a diagnosis. They often compensate through memorisation, avoidance, or careful career choices. However, these strategies break down when academic or workplace demands increase.

Because of this, accurate adult assessment becomes essential. This kit helps professionals give adults clear, respectful feedback and a solid understanding of their learning profile. It also supports applications for university accommodations, vocational training adjustments, and workplace support.

The Three Dyslexia Subtypes

The Adult Dyslexia Assessment Kit identifies and rates three core subtypes:

Dysnemkinesia

This subtype involves difficulty remembering the motor movements for writing. Adults may show poorly formed letters, reversed characters, or inconsistent spacing. Handwriting often appears slow or hard to read.

Dysphonesia

Here, the person struggles to link sounds to written forms. Decoding unfamiliar words, reading complex language, and spelling phonetically become difficult. Adults often rely on memorisation instead of true decoding skills.

Dyseidesia

This subtype affects whole-word recognition. Adults may read slowly, struggle with irregular words, and make frequent visual errors when reading or spelling.

Each subtype receives a severity rating—mild, moderate, or severe. These ratings help professionals plan targeted interventions and meaningful support.
