WASHINGTON — Even if you believe that the Common Core standards are high quality, internationally benchmarked and would provide a solid foundation for the American education system, you should be worried about how they are being implemented. If the Common Core standards — which are meant to define what knowledge and skills should be acquired by students during their K-12 education — are not integrated into the American education system with care, any positive attributes that they may have will be washed out by incoherence, misalignment and evaporation of political support. That said, there is ample reason to believe that the standards are not being implemented with care.
