Hi,
I did a Google search on Paul Idaho High School and nothing appeared. They do have a junior high and an elementary. I'd look them up and call them first.

Paul doesn't seem to have a genealogy society or historical organization.

I'd contact the Minidoka County Historical Society, minidoka.id.us/historical-society/d... They might have the old year books.

If not, I'd contact the Idaho State Historical Society, idahohistory.net/1890_census.html . Successful Searching!
