Detailed analyses show how Benchmarks for Science Literacy relates to national content standards for science, mathematics, and social studies. Curriculum developers and framework designers can use this component to compare their own state or district level guidelines to the national content recommendations; teachers can use it to evaluate how effectively curriculum materials or activities address a benchmark or standard. In particular, the comparison of Benchmarks and National Science Education Standards makes it much easier to deal with both benchmarks and standards when making decisions about curriculum, instruction, and assessment.
