ACCI Assessment | American Communication Cohesion Index™
FOUNDER PRICING NOW IN EFFECT!
Most communication assessments measure English proficiency. The ACCI measures something harder to see — and more expensive to ignore.
The American Communication Cohesion Index™ is a scored communication assessment for professionals and their spouses/partners, graduate students, and anyone navigating American-facing environments.
It evaluates both sides of the communication gap — not just the global professional adapting to American norms, but the American professional whose habits may be creating friction without realizing it.
Fluency isn't the same as cohesion.
Your team is talented. Your colleagues are qualified. Everyone speaks English.
Yet something keeps getting lost. Meetings run long and land nowhere. Emails require follow-up. A client relationship that should be thriving feels stuck. A colleague you respect doesn’t seem to understand you, and you’re not sure why.
The breakdown usually isn’t vocabulary. It isn’t grammar. It’s cohesion—the ability to communicate clearly, naturally, and effectively in the specific context of American professional and social environments.
Cohesion gaps run in both directions. Global professionals adapting to American communication norms. As well as, American professionals whose pace, idioms, and topic-switching create barriers for global colleagues. Both sides contributing to a productivity cost that nobody has named.
Until now.

How it all began...
Built from real experience.
Validated in the real world.
The ACCI and the IDEA Methodology™ were developed by Allison O’Dell — not in a classroom, but across more than three decades of working in environments where communication cohesion directly determined outcomes.
Allison holds a double major in Finance and Marketing from Babson College, Magna Cum Laude, with a concentration in Communications. Her professional background spans a vast array of experiences, including as an Investment Principal and Compliance Officer in banking, Real Estate Broker, Training Designer, Luxury Hospitality Manager, and Global Communication Consultant — a cross-industry career recognized with awards in training design and professional performance. This breadth gives her a perspective on communication effectiveness that no single-industry specialist can replicate.
Since entering the field of global communication instruction, Allison has taught over 700 lessons to international professionals, graduate students, and the spouses and partners of relocated professionals — working with clients from more than a dozen countries across four continents. The ACCI was developed and refined directly from this work, and tested with real global English speakers.
