(Salem, OR)  --  Oregon lawmakers are considering a proposal to require students to pass the U.S. Naturalization Test in order to earn a high-school diploma.  It would require K-12 students to correctly answer 60 of the 100 questions on the civics portion of the naturalization test given to immigrants by U.S. Citizenship and Immigration Services.  A work session on the bill is slated for three o'clock this afternoon in Hearing Room C.
