Success Story
Head Start began in 1965 and is the longest-running national school readiness program in the United States. Nearly 25 million low-income children and their families have benefited from Head Start's education services.
In 2007 Congress required Head Start to include research-based performance standards in its program monitoring. Head Start chose the CLASS tool for its nationwide improvement efforts. It is being used in all 50,000 Head Start classrooms int he U.S. as a measure of high quality teaching.
"With an assessment tool like CLASS, we've found a missing piece of the puzzle that we've been looking for, for a very long time," reports Amanda Bryans, director of the Office of Head Start's Educational and Partnerships Division. "This tool...[focuses] on something that we know is so important to a young child's life: supportive relationships built on quality interactions."
