Book excerpt: This book comprehensively evaluates early childhood inclusion over the past 25 years. Based on their research and extensive experience, the authors examine benefits and drawbacks of inclusion, leading influences on inclusion, and issues that face children in different environments with different developmental challenges. The book shows professionals, instructors, and students in early intervention and early childhood education where inclusion is today and what they need to do to keep the field moving forward. The final chapter presents a national in-scope agenda for change - a framework of ideas for meeting challenges and achieving an agreed-upon set of principles and practices - in order to create optimal educational environments for all children.
