One of the most significant aspects of a child’s life revolves around their age. 

This helps determine various expectations such as skill development and academic grade level. 

Historically, during ancient times, it was common to have students of different ages sectioned together. 

However, with the rise of the Industrial Revolution, the age sectioning and grade-based educational system were introduced for the purpose of efficiency and stricter regulations. 

Indeed, early education and milestones are commonly influenced by a child’s age. 

However, it’s important to recognize that each child is unique, and even children of the same age can progress and achieve milestones at different rates.

    While age provides a starting point, it may not always accurately reflect every child’s individual abilities.

    Recently, schools have started adopting mixed-age grouping again to offer students better educational possibilities.

    However one might still ask,

    What are the disadvantages of mixed-age preschool? Five of the most common disadvantages of these type of preschools is their demands for the teacher to be very trained, their deviation from the standard curriculum, varying abilities of children, and their susceptibility to misuse. In this article, we’ll discuss each of these disadvantages along with their advantages and benefits for your toddlers.

    What Are Mixed-Age Classrooms?

    Before we delve deeper into the disadvantages and advantages of mixed-age classrooms, it is of much importance to paint a picture of the situation.

    Also known as a multi-age classroom, this type of learning operates in a way that children from different age ranges are sectioned together in one class and get the same materials at once. Most commonly used in Montessori classrooms, this type of sectioning is in contrast to the traditional system of the children being divided by age, which is known as a single-age classroom.

    Picture this, a younger kid, probably a three-year-old, learning mathematics together with an older kid, who is more or less six years old, in one classroom. Older children learn from younger kids and younger kids learn in the same way from older kids.

    In theory, this scene can be depicted as a collaborative environment for the two age ranges, but in practice, it comes with its own disadvantages.

    Mixed Age Classes Pros and Cons

    Exploring the dynamics of mixed-age classes shows both advantages and challenges in education. This approach brings together students of different ages within the same classroom, fostering unique learning experiences. Understanding the mixed-age class pros and cons helps educators and parents make informed decisions about its suitability for children’s growth and development.

    5 Disadvantages of Mixed-Age Groups in Early Childhood (Cons Of A Mixed-Age Classroom)

    So why is Montessori bad or what are the cons of mixed-age classrooms according to some and what are the disadvantages of mixed-age groups in early childhood? Here are 5 cons of a mixed-age classroom:

    1. Demands on the Teacher

    In a classroom where students of different ages are sectioned together, there is a broader spectrum of abilities compared to a class composed of students from a single grade. 

    In order to effectively teach in such a setting, teachers require specialized training in instructional strategies and material development. 

    Traditional textbooks often aren’t aligned well with the needs of a mixed-age classroom as they are typically designed for specific grade levels. 

    Consequently, teachers are responsible for the supervision and creation of materials that cater to the diverse needs of their students. 

    In instances when children are not separated by age is implemented to reduce costs, teachers may also encounter larger class sizes, which further adds to the challenges of planning for multiple skill levels.

    1. Deviance from Standard Curriculum

    The curriculum standards in numerous states are organized according to specific grade levels and serve as the foundation for standardized testing. 

    However, when it comes to instruction in multigrade classrooms, it can be challenging to fully address all the learning objectives for each individual grade level. 

    With careful planning of the lesson course, students in multigrade classrooms may ultimately achieve mastery of all the objectives before progressing to the next classroom level. 

    However, their learning sequence may differ from their peers in single-grade environments, especially in subjects that heavily rely on sequential instruction, like mathematics.

    1. Varying Degree of Ability

    Planning instruction for the entire class can become very challenging for teachers when there is a varying range of academic abilities present. 

    While some students may be prepared for multiplication, others may still be focusing on multi-digit subtraction. 

    Although variation in ability exists in all classrooms, it can be more pronounced in mixed-age classes.

    Grading also poses a challenge in multi-age classrooms since it is neither feasible nor equitable to apply the same grading standards to all students. 

    As a result, multiple evaluation systems may be employed to address this issue.

    1. Susceptibility to Misuse

    Some schools purposefully adopt systematic multigrade sectioning due to the cognitive and social advantages they provide as outlined in their respective curriculum.

    However, the majority of schools that utilize mixed-age groupings do so out of necessity or as a cost-saving measure. 

    In cases where mixed-age sectioning is implemented to reduce costs or accommodate declining enrollment, there is a higher likelihood that teachers may not receive sufficient preparation and support for this type of instruction.

    5 Pros of Mixed-Age Preschool

    1. Forges Collaboration

    Lev Vygotsky’s theory of Social Constructivism forms a fundamental basis for contemporary approaches to children’s learning. 

    According to his theory, the most effective learning takes place when individuals are engaged in a task and receive guidance and support from someone more knowledgeable most commonly referred to as “scaffolding”. 

    Through this scaffolding, individuals can successfully accomplish challenging tasks and enhance their own performance levels. 

    However, a common challenge arises in classrooms where there are limited numbers of teachers and a large number of students, making it difficult to scaffold every student simultaneously. 

    This is where mixed-ability sectioning comes into play as a solution. 

    In such cases, older children can provide support and guidance to younger ones, while younger children can look up to the older ones as role models. 

    1. Inclusive Learning 

    The concept of the mixed-age method is particularly beneficial when considering the inclusion of children with disabilities. 

    According to Katz and McClellan (1997), children who struggle to connect with peers of the same age often find it easier to establish and maintain positive relationships with either younger or older children. 

    This difficulty in relating can arise from various factors, including disabilities or simply shyness. 

    Regardless of the cause, having a classroom composed of children of different ages eliminates the need for anyone to feel judged or inadequate. 

    Instead, all children have the opportunity to form connections with others in ways that resonate with them individually.

    1. Builds Confidence

    Children acquire essential cooperation skills and develop a sense of empathy towards others, as well as self-care, through their participation in mixed age preschool.

    Being part of a classroom that includes both older and younger peers enables them to establish a sense of security, knowing that there are individuals with varying levels of experience. 

    This fosters a child’s self-confidence and self-esteem.

    In mixed age groups, children benefit from unique and enjoyable learning experiences. 

    The presence of multi-aged sectioning allows children to express their own perspectives and engage in collaborative interactions rather than engaging in competition. 

    This approach nurtures their individual abilities and strengths in a more effective manner, resulting in a more enjoyable and impactful learning environment.

     4. Fosters Leadership Skill

    When older students are given the opportunity to teach younger students, they develop leadership skills such as communication, organization, and problem-solving. 

    Mixed-age preschools often offer a variety of opportunities for students to lead, such as leading class projects, serving on committees, or organizing events. 

    These opportunities help students to develop their leadership skills and to learn how to work effectively with others.

    In addition to these specific benefits, multi-age classrooms can also foster this skill in more general ways. 

    By interacting with students of different ages, students learn to appreciate diversity and to see the world from different perspectives. 

    They also learn to work together and compromise, which are essential skills for leaders.

    Why Is It Important To Have Mixed Age In Preschools?

    While many daycare centers tend to follow the model of having all children in a single large class, there are relatively few preschools that fully embrace the mixed-age approach, with Montessori schools being notable exceptions.

    Extensive research consistently demonstrates highly positive outcomes for children in different age sectioning, especially in terms of socio-emotional development. 

    Studies focusing on the skills that young children require to succeed in elementary school and beyond consistently prioritize socio-emotional skills as being of utmost importance. 

    These skills include communication, self-regulation, attention, and building relationships. 

    These are precisely the skills that children should be learning in preschool, and multi-age classrooms excel at teaching them.


    While mixed-age classrooms offer significant educational benefits, they also present certain challenges. 

    If you are contemplating implementing this type of early childhood classroom in your program, it is crucial to ensure that you have the necessary resources and strategies in place. 

    These resources should enable you to build upon existing teaching methods and effectively adapt to the unique needs of each child within the setting.


    Is there a better age to move to a mixed-age program? There is no one-size-fits-all answer to this question, as the best age to move to a multi-aged room will vary depending on the individual child. However, there are some general guidelines that can help parents make a decision. At age 3, many children start interacting with older and younger peers. At age 4, children are typically more independent and self-sufficient at this age and they are also able to follow directions and participate in collaborative activities. At age 5, it can be a good time for children to start getting used to interacting with a variety of ages.

    What are the benefits of mixed-age preschool? There are many benefits to this type of preschool. Some of the most notable benefits include enhanced leadership skills, boosts self-esteem, more individualized education, and stability of classmates and teachers.

    Are multi-age groupings good for kids? Yes, multi-age classes can be very beneficial for kids. These types of classes allow the children to learn at their own pace, learn from each other, develop social skills, and develop a sense of community.
