Practical guidance and methodological components for working with the National Criteria Catalog. With this book, the author group led by Wolfgang Tietze and Susanne Viernickel supplements the National Criteria Catalog "Educational Quality in Daycare Centers for Children" with a practical guide aimed at systematically improving the quality of facilities. The materials accompany and support leaders and teams on the path of systematic quality development, from self-assessment of educational work to goal agreements and planning concrete steps, all the way to documentation and securing what has been achieved. All materials and forms are provided as photocopy templates in the book as well as on the accompanying CD-ROM, encouraging consistent implementation, such as checklists for the 20 quality areas in daycare centers for children.
