An authorized medical professional must evaluate the applicant in person or, where state law permits, through a real-time telehealth examination, to diagnose the condition that prevents the applicant from completing the educational requirements. The medical professional may need to provide a clinical diagnosis and explain how the disability or impairment affects the applicant's ability to meet the English and/or civics requirements.
