I propose the red corrections:
<EducationLevel>
<Junior T="a secondary or junior education "/>
<masters T="a masters program"/>
<doctorate T="a doctorate program"/>
<phd T="a Ph.D. program"/>
<post_doctorate T="a post doctorate program"/>
When only input = “Illiterate”, the narrative says: “WhoEver attended for illiterate.” The following may be better: “WhoEver is/was illiterate.”
<EducationAchievement>
<Unknown T="with an unknown of achievement level"/>
