The materials reviewed for Carnegie Learning High School Math Solution Integrated series meet expectations for alignment to the CCSSM for high school. For focus and coherence, the series showed strengths in the following areas: attending to the full intent of the mathematical content contained in the standards, attending to the full intent of the modeling process, spending the majority of time on the content from CCSSM widely applicable as prerequisites, allowing students to fully learn each standard, requiring students to engage in mathematics at a level of sophistication appropriate to high school, and being mathematically coherent and making meaningful connections in a single course and throughout the series. In Gateway 2, the materials meet expectations for rigor and practice-content connections. In Gateway 3, the materials meet expectations for Usability.
