What Germany’s All-Day School Expansion Teaches Us About Quality

By Wolfram Rollett, Professor at the University of Oldenburg

Over the past two decades, Germany has undergone one of the largest educational transformations in Europe: the rapid expansion of all-day schooling.

At the beginning of the 2000s, all-day schools were relatively uncommon in Germany. Today, they are a central part of the educational landscape, with millions of students participating across the country. This development represents far more than a logistical change in scheduling. It reflects a growing understanding that schools must support not only academic learning but also children’s broader social, emotional, and developmental needs.

However, Germany’s experience also teaches us something very important: expanding time is not the same as creating quality.

Germany’s educational system is highly decentralized, with responsibility divided across sixteen federal states. As a result, there is no single German all-day school model. Some schools operate highly integrated systems where teachers, educators, and youth workers collaborate closely across the entire day. Other schools function more like separate shifts, where afternoon programs have little connection to the instructional work of the morning.

This diversity creates both opportunities and challenges.

Officially, Germany defines an all-day school through several minimum criteria: schools must offer programming at least three days per week, the day must extend to at least seven hours, lunch must be available, and the school leadership must oversee the program. But these structural definitions alone tell us very little about the actual experiences students have.

This is where research becomes critical.

Over many years, German researchers have studied the developmental effects of all-day schooling. One of the most important findings is that additional time by itself does not automatically improve outcomes. Simply keeping children in school buildings longer does not guarantee better learning, stronger well-being, or improved social development.

Instead, what matters most is the quality of students’ experiences.

German all-day school research suggests that positive developmental effects emerge when students participate regularly over time and when they experience programs as meaningful, supportive, engaging, and relationally positive. Students need to feel cognitively stimulated, emotionally supported, respected, and included. They need opportunities for participation and autonomy. Most importantly, they need positive relationships with adults.

One of the strongest lessons from German research is the importance of student perception. Adults often design programs based on policy goals or organizational structures, but student perspectives are central for understanding whether those environments function as meaningful developmental settings.

In large-scale studies involving thousands of students and families, German researchers have found that when students reported high-quality experiences—when they enjoyed activities, trusted adults, and felt supported—we were more likely to observe positive developmental outcomes. Student voice was not a secondary factor. It was central.

This has major implications for educational policy internationally.

Too often, educational reform focuses primarily on structure: more hours, more programs, more infrastructure. These are important foundations, but they are only the beginning. The real educational question is what children experience during that additional time.

Another major challenge in Germany concerns staffing and professionalization. All-day schools often involve highly diverse workforces, including teachers, social pedagogues, youth workers, volunteers, and external providers. In some schools, collaboration between these professionals is excellent. In others, staff work under very different conditions, contracts, and expectations, with limited coordination or shared planning time.

This means that quality depends heavily on local school leadership and organizational culture.

Germany’s next challenge is therefore not expansion, but quality development. Schools must systematically ask themselves: Who participates? How consistently? In which activities? And most importantly, how do students experience those activities?

The future of all-day education depends on our ability to answer these questions honestly.

I believe Germany’s experience offers an important international lesson. Extended education should not simply extend institutional time. It should create richer developmental opportunities for children and adolescents. When schools succeed in combining meaningful participation, strong relationships, and thoughtful pedagogy, additional time can become educationally meaningful and support students’ development.
