This compilation was prepared to assist grantees implementing the Head Start Program Performance Standards. This guide includes all of the program performance standards that are required to operate Head Start, Early Head Start, American Indian and Alaska Native and Migrant or Seasonal Head Start programs. The guide covers the full range of operations from enrolling eligible children and providing program services to those children and their families, to managing programs to ensure staff are qualified and supported to effectively provide services. This guide also focuses on using data through ongoing program improvement to ensure high-quality service. As required in the Act, these provisions do not narrow the scope or quality of services covered in previous regulations. Instead, these regulations raise the quality standard to reflect science and best practices, and streamline and simplify requirements so programs can better understand what is required for quality services.
