DES MOINES — A decision by the superintendent of Iowa’s largest school district to stick with remote learning in the midst of a pandemic could end up costing him his job. The Iowa Board of Educational Examiners is seeking to strip Des Moines Public Schools Superintendent Thomas Ahart of his administrator license, saying it found probable cause that Ahart failed to submit or implement a lawful plan to return students to the classroom for the 2020-21 school year, television station WOI reported Wednesday.
