Michigan officials say they will push toward a goal of having 100 percent of the state's core-subject teachers "highly qualified" by the end of the year despite an offer from the federal government to extend a looming deadline. The state has worked with Detroit Public Schools and Wayne State University to get certification for teachers instructing in areas that are outside of their college majors and minors. In three years, a total of 185 Detroit teachers have received training through the program.
