Which vendor administers the Ohio insurance producer licensing examination on behalf of ODI?

Why this is the answer

Per the ODI Producer Licensing Handbook and current vendor contract, Ohio's producer licensing examinations are administered by Pearson VUE at approved test centers and online with proctoring. Prometric and PSI Services hold testing contracts in other states; ExamFX is a pre-licensing and CE content provider, not an exam vendor. After completing pre-licensing education under R.C. 3905.04, a candidate schedules the exam directly with Pearson VUE and presents valid state-issued ID at the test center.
