Experts from Rhode Island College were brought in for the Plaintiff's side to judge the effectiveness of the school board's new plan. From April to November 1969, McMillan repeatedly ordered the board to revise the plan. The Board eventually submitted a plan rezoning neighborhoods into pie-shaped wedges, where blacks living in the center of Charlotte would be divided up and distributed to outlying, formerly white high schools. The school board's plan required busing and would achieve a black population of 2-36% in all ten of the high schools. Due to the greater number of elementary schools, elaborate gerrymandering was required and would achieve greater integration, but would leave more than half of black elementary students at majority-black schools.
