They are enthusiastic about implementation, but also realistic, recognizing that it will be challenging and they will need to adjust their teaching practice. Teachers also call for more professional development and resources to implement the standards. "I see teachers' real experiences in the Primary Sources findings about the Common Core State Standards," noted Naima Lilly, a mathematics educator in New York City. "I believe the standards are holding students and teachers to higher expectations and providing consistency in a positive way. While implementation can be daunting at the beginning, I'm confident that in the long run it will all be worth it." Key advance findings include: Overall, 73 percent of teachers who teach math, English language arts (ELA), science and/or social studies in Common Core states agree they are enthusiastic about the implementation of the standards in their classrooms. Math and/or ELA teachers (77%) and elementary school teachers (81%) expressed the highest levels of agreement, while their middle school and high school teacher peers have lower percentages of agreement at 71 percent and 57 percent, respectively.
