A) Any teacher not certified by the department of education is unqualified.
B) The department of education is the entity best equipped to determine which teachers are qualified.
C) Unqualified teachers are less effective than qualified teachers.
D) The school in question has more uncertified teachers than any other school the parent is considering.
E) None of the teachers who are uncertified are in the process of becoming certified.
