The announcement of class assignments often raises questions for parents. If your child is placed in a multi-level class (also known as a double-level or multi-age class), you might wonder if this will hinder their learning or, on the contrary, offer them new opportunities.
At École M, we consider age mixing a true educational asset. Inspired by the work of Maria Montessori and recent neuroscience research, the multi-age classroom transforms the school into a small living community. Discover why this model is ideal for the first years of schooling. Let's take a closer look at the advantages and considerations of this system.
Unlike the traditional "single-level" classroom, a multi-level classroom brings together students from different cycles or age groups (for example, Middle Section and Grande Section together).
Far from being an exception, this model applies to nearly one in two students in France, according to the University of Montpellier. For teachers, this requires moving away from traditional lectures towards differentiated instruction, where each child progresses at their own pace.
Between the ages of 2 and 6, there is a vast difference in development. It is precisely this diversity that creates a learning dynamic through imitation.
One of the most notable advantages of multi-age classrooms is the promotion of student independence. Older children can serve as role models for younger ones, helping them acquire organizational skills, time management, and independent learning. This independence is essential for developing self-confidence and responsibility.
The benefit: Children learn to organize themselves, manage their time, and find solutions independently. This skill is a major predictor of success in middle school.
In a mixed-age classroom, mutual help comes naturally. An older child will spontaneously help a younger child put on their coat or choose an activity. This tutoring system, valued by the National Education Scientific Council, significantly reduces aggressive behavior and promotes kindness.

Every child has their own developmental pace. At 3 years old, some children still need longer naps or time for sensory exploration. In a mixed-age classroom, the entire group is not forced to do the same thing at the same time. Differentiated instruction allows for respecting each child's sleep and learning pace, moving away from the rigidity of traditional classrooms.
In a mixed-age classroom:
Multi-age classrooms foster intergenerational communication. Students have the opportunity to interact with peers of different ages, which can broaden their understanding of the world and encourage respect for differences. Younger children can benefit from the advice and encouragement of older students, while older students strengthen their skills by explaining concepts to the younger ones.
In multi-age classrooms, children often have the opportunity to review and reinforce fundamentals, as they are exposed to concepts at different levels. For example, a second-year student can review math skills they have already learned while attending first-year math lessons. This can help consolidate foundational knowledge and strengthen the understanding of concepts.
Multi-age classrooms, where students of different ages and levels are grouped together, help children find their place within the group by promoting individualized learning, encouraging diverse social interaction, creating natural mentoring opportunities, reducing competition, and strengthening their sense of belonging.
One of the main challenges of multi-age classrooms is the demands placed on the teacher. They must plan lessons adapted to different levels, which can be time-consuming. Individual student monitoring can also be more complex, as the teacher needs to respond to the varied needs of each child.
In conclusion, multi-age classrooms have their advantages, particularly promoting autonomy, intergenerational communication, and a strengthened learning of fundamentals. However, they also have drawbacks, such as management challenges for teachers. The success of multi-age classrooms largely depends on adequate planning and implementation by the school and teachers, as well as support from parents and the educational community.
At École M, we have designed our classrooms so that each age group finds its place. Following the recommendations of the French Institute of Education (IFÉ), we promote cooperation rather than competition. Our teachers are trained to support both potty training for the youngest children and the beginnings of reading for the older ones.

At École M, we favor an organization by developmental cycles to respect the child's natural pace. Generally, our classes group together:
We have chosen small class sizes to ensure highly personalized support. Unlike traditional preschool classes that can have up to 30 students, our small classes allow the teacher and ATSEM to dedicate quality time to each child, thereby facilitating the implementation of differentiated teaching.
Mixing 2-4 year olds is ideal for the first stages of schooling:
For children aged 4 to 6, the Middle Section / Reception Year mix promotes autonomy and preparation for CP (Year 1):
Thanks to small class sizes, the teacher can organize the class into small needs-based groups. While one group is engaged in a language session, the other group works independently on hands-on activities inspired by the Montessori method. This format allows each child to progress at their own pace, without ever being held back or challenged by the overall class level.
