Three sister teachers in the Chicago Public Schools system used a math curriculum-writing project to bilk the Chicago school system out of $450,000 in less than 3 years. The ringleader of the group, Judith Branch-Boyd, earned $164,400 in 2001-2002, while using her position to employ her two sisters, Toni Branch and Brenda Hambright. An uncertified teacher, Ms. Branch had attempted to pass the certification exam seven times. Unsurprisingly, the math curriculum contained "numerous errors, including basic computation errors and word problems where the solution given was the wrong answer."
