Research for Action's Year Two evaluation report indicates that most lead teachers demonstrated high fidelity to the key elements of the Blueprint approach in the classroom, though some teachers experienced issues related to differentiating instruction and the simultaneous implementation of Blueprint and Creative Curriculum. The authors found strong evidence of impact on teachers and students: multiple data sources demonstrated that teachers and children in Blueprint centers benefitted from the Blueprint curriculum and professional development. Children in Children's Literacy Initiative (CLI)-served classrooms made 2-3 months of additional progress in vocabulary development compared to children in similar classrooms not supported by CLI. Though less than a quarter of lead teachers in Blueprint classrooms in Spring 2018 received intended amount of training and coaching due to high turnover and variable attendance, most teachers had at least attended the Introduction to Blueprint 3.0 training and received at least one full year's worth of coaching (over 20 hours). This report is comprised of two studies that provide in-depth findings of Year Two Blueprint implementation (resources and activities) and impacts (teacher and student outcomes). Study 1: Blueprint Implementation is a descriptive study of the quality of implementation of Blueprint in 11 Philadelphia pre-K centers. This study also followed up on findings from Year One, including an in-depth exploration of challenges to implementation-- consistent attendance at trainings, finding time for coaching conferences, and coaching amidst high teacher turnover--and CLI strategies to address them. Study 2: Impact of Blueprint on Teachers and Students is a study that employed a mixed-methods quasi-experimental research design, involving 11 centers receiving Blueprint professional development and curriculum and 11 centers serving as a comparison group.
