The Center on Enhancing Early Learning Outcomes (CEELO) and the Center on School Turnaround (CST) collaborated to develop case studies of three selected schools receiving SIG funds that have, with the support of their districts, promoted the use of early childhood programming (PK-3) as a key strategy in their schools' turnaround models. The goal of this document is to increase the awareness and understanding of how to effectively embed PK-3 strategies in school turnaround efforts within the SIG program. Thus, we sought schools where specific practices in the PK-3 years aligned with and accelerated promising turnaround efforts through the implementation of the SIG models. The schools considered include Orchard Gardens K-8 School in Roxbury, MA; Mann Elementary School in St. Louis, MO; and, Elliott Elementary School in Lincoln, Nebraska.
