This document provides the Side-by-Side Comparison, a tool to assist early care and development programs receiving funds from both Head Start and the California Department of Education to prepare for state and federal program monitoring reviews and to conduct self-evaluations. The instrument is designed to be used for the California coordinated compliance review (CCR) and the federal Head Start program compliance monitoring process, Program Review Instrument for Systems Monitoring (PRISM). The instrument also lists suggested documentation that can be used to demonstrate compliance with CCR items and PRISM core questions. The introduction explains the purpose for this instrument, identifies challenges for co-located programs, and describes how to use the instrument. The remainder of the instrument is organized in six sections, according to the CCR key dimensions. Each section displays in column 1 the CCR compliance items and codes delineating the child development programs affected, alongside the related PRISM core questions and performance standards in column 2. Suggested documentation demonstrating compliance for each process is displayed in columns 3 and 4, respectively. The areas assessed by this instrument are: (1) standards, assessment, and accountability; (2) teaching and learning; (3) opportunity (equal educational access); (4) staffing and professional growth; (5) parent and community involvement; and (6) governance and administration. Appended are references from the Code of Federal Regulations for Head Start performance standards related to each core question. (KB)
