The Method That Works
In the 1930s, neuropsychiatrist Dr. Samuel T. Orton and educator Anna Gillingham developed an approach to reading intervention that is still, nearly a century later, the gold standard in clinical literacy work. Orton-Gillingham is not a curriculum. It is a prescriptive, diagnostic instructional philosophy built on three principles that set it apart from everything else.
Simultaneous Multisensory Instruction
OG engages multiple sensory pathways simultaneously — visual, auditory, tactile, and kinesthetic-motor. A student learning the letter-sound correspondence for /b/ doesn't just see the letter. They say the sound, trace the letter, feel the lip-pop of the phoneme, and write it. All at once. This multisensory convergence forges neural pathways that single-channel instruction cannot.
Diagnostic Precision
OG is deployed in 1:1 settings with continuous oscillation between assessment and instruction. The tutor is always diagnosing: where exactly is this student's gap? The instruction is calibrated, in real time, to each learner's current ceiling.
Systematic and Cumulative Sequence
OG builds from the simplest units to the most complex, with mastery at each level required before advancing. No gaps. No guessing. Each new pattern is introduced in the context of everything learned before it.
The Price Problem
Clinical OG intervention costs between $1,200 and $2,500 per student per year. Programs like the Barton Reading and Spelling System cost $299 per level, with 10 levels. Proper clinical intervention is available only to families with both awareness and disposable income.
What GSU Built Instead
The Reading Arsenal is nine interactive labs built on the same Structured Literacy and OG framework. The Spelling Patterns Forge delivers the five-step OG drill cycle — HEAR, SAY, TAP, BUILD, WRITE — interactively. And GENO provides the 1:1 diagnostic attention that is OG's defining feature — free, 24/7, in 32 languages. No waitlist. No fee. No login.
