This page lists High Schools starting with the letters OV based on the listed high school name. Note that sometimes schools are listed with the full name of the person for whom it was named (Abraham Lincoln) or the last name (Lincoln). Different schools have different preferences and different sources list schools differently. Its best to use the search function on the site to find all schools by a text string.
Its also noteworthy to say that this is not a full list of schools starting with these letters. Its only the schools in our database of 14,000+ schools. It is based almost exclusively on having at least one alumni in our system.
