What does assessment look like in Montessori?
Rebecca Lingo • June 24, 2024

Often we are asked how our highly trained teachers assess children’s work and progress without relying on quizzes, tests, or grades. If we remember that Montessori is about learning for life, we can flip this question and ask, how does assessment work when we move outside school walls and step into the world of work? In our work environments, do we have tests and grades? If so, how do they help us grow and improve in what we do?


Interestingly, a 1999 document “An Employer's Guide to Good Practices” from the U.S. Department of Labor Employment and Training Administration, has a whole chapter on issues and concerns with assessment, including the “limitations of tests in providing a consistently accurate and complete picture of an individual's related qualifications and potential.”


Dr. Montessori designed assessments that provide an accurate reflection of thinking and problem-solving?


It’s worth thinking about what we want to assess. Do we want students to just acquire new content knowledge or be able to apply this knowledge to new or existing situations? Do we want to see if students can produce something that demonstrates their understanding of the content or skill? Do we want to assess their writing ability, speaking skills, creativity, collaborative process, or organization?

If we focus on authentic assessments, we are asking that students apply what they have learned to a new situation, or perhaps we are requiring them to use some judgment to think about what information and skills are relevant and how they can be used. Similar to how adults are “tested” in work or personal life, often authentic assessments are tied to a real-world or complex situation. 


In addition, authentic assessments offer students the opportunity to rehearse, practice, consult resources, and get feedback to refine what they are doing. Students can be innovative in this process and as a result, are often extremely self-motivated. 


In our elementary and adolescent communities, authentic assessments may take the form of:


  • Role-playing or performing a historical event and exploring what might have happened if things during that time had changed.
  • Drawing a diagram of how a process works and showing what happens if a variable changes.
  • Creating an advertisement or brochure to highlight qualities or review something learned.
  • Writing a diary entry for a real or fictional character.
  • Composing a poem, play, newspaper article, or persuasive letter to share important concepts. 
  • Writing a letter to a friend explaining a problem or technique. 
  • Insert your idea here.


Wheaton Montessori students love demonstrating what they have learned in creative, authentic ways. They present to their peers. They grapple with concepts. They even sometimes teach younger classmates. 


But how do teachers keep track of this learning?


In addition to authentic assessment, our teachers are also using their extensive training in scientific observation techniques to understand students’ learning process, steps toward mastery, and needs for support. This is called formative assessment.


Formative assessment is a continuous, low-stakes, responsive process. This means that students are getting feedback and information while their learning is taking place. Through observation, the teacher is gauging students’ progress, determining what has been effective, and identifying what could be improved in the learning process. There are no grades involved, however the goal is mastery of the skill or content. 


At all levels of Wheaton Montessori School’s classroom, formative assessment can look like:


  • The guide observes students during a lesson presentation and the student’s independent follow-up work. 
  • Student reflection in work journals. 
  • One-on-one conferencing with the guide and the student.
  • Discussion and review lesson of content or skills. 
  • Students informally or formally present their work. 
  • Student self-evaluations.
  • Students correct their mistakes and reflect on what they learned from those mistakes.
  • The teacher observes the student giving a lesson to another child.


Formative assessment doesn’t have to be teacher-driven. In fact, in Wheaton Montessori classrooms, students always get feedback and information about their learning from the classroom materials, many of which are designed to help children learn from their mistakes as they check their work. They don’t even have to be aware that they are learning through their mistakes.


Formative assessment is a collaborative process that happens “with” students rather than “to” students. Montessori students and teachers partner to get to know their strengths, interests, and needs. Because this is an ongoing, collaborative process, the teacher and students can make small, immediate, impactful decisions to support well-being, learning-goal achievement, and self-efficacy. 


What are the results?


When students experience authentic and formative assessment as integral aspects of their education, they become self-directed learners because they are active agents in their learning process. This translates to agency in other environments and throughout life. 


In Wheaton Montessori classrooms, we focus on getting an accurate and complete picture of children’s skills and potential. Contact the office to learn more about what this looks like in action!

How Geometry Got Its Name
By Rebecca Lingo February 2, 2026
In Wheaton Montessori School classrooms, we like to introduce big ideas with big stories. We offer children a sense of wonder first, sort of like an imaginative doorway, so that when they later study formulas, theorems, and proofs, they already feel connected to the human story behind them. One of these stories is The Story of How Geometry Got Its Name, an introduction to a subject that is far older than the textbooks and protractors we encounter today. In Montessori, Geometry is more than about shapes. It is about human beings solving real problems in the real world. A Problem as Old as Civilization To reintroduce geometry, we time-travel back around 5,000 years to the ancient civilization of Egypt. This was a land shaped by the Nile River, the longest river in the world. Each year, the Nile flooded its banks as snowmelt poured down from the mountains far to the south. The Egyptians depended on this yearly flood as it left behind rich, dark silt that nourished their crops and made life possible in an otherwise harsh desert. But the flood created a challenge, too. It washed away the boundary markers that separated one farmer’s field from another. When the waters receded, no one could quite remember where their land began and ended. Arguments ensued. “This corner is mine!” And the fields needed to be measured and marked again. The First Geometers: The Rope Stretchers To solve this annual problem, the Egyptians relied on a special group of skilled workers called the Harpedonaptai, or Rope Stretchers. These were early land surveyors who used a knotted rope tied at regular intervals and three weights to create a very particular triangle. In our elementary classrooms, we invite a few children to hold a prepared rope at its large knots, forming that same triangle. As they stretch it out and lay it on the ground, many quickly recognize what the Egyptians had unknowingly created: a scalene right-angled triangle. This shape would later become central to the geometry studied by Greek mathematicians. The Harpedonaptai used this simple tool to re-establish field boundaries, set right angles, and make sure the land was measured accurately and fairly. Geometry, in its earliest form, served a deeply practical purpose. From Rope to Pyramid The Harpedonaptai’s expertise was valued far beyond the farmlands. They also helped lay out the foundations of temples, monuments, and even the Great Pyramid of Giza. The base of the Great Pyramid is a perfect square, which is an astonishing feat of measurement and design. The Pharaoh himself oversaw these measurements, but it was the Rope Stretchers who executed them. Their work represents one of humanity’s earliest recorded sciences: the careful measuring of the earth. How Geometry Got Its Name The name geometry reflects this ancient practice. It comes from two Greek words: gê — earth metron — measure Geometry literally means earth measurement. The Egyptians did not use the language of right angles, nor did they classify triangles as we do today. Their work was grounded in practical needs. They needed to solve problems, organize land, and create structures that would endure for thousands of years. Yet their discoveries influenced later thinkers like Pythagoras, who likely traveled to Egypt and learned from their methods. Over time, the simple knotted rope inspired a whole discipline devoted to understanding lines, angles, shapes, and the relationships between them. Why We Tell This Story in Montessori When Montessori children hear this story, something important happens. Geometry becomes more than a set of rules or vocabulary words. It becomes a human endeavor born from curiosity, necessity, and ingenuity. The heart of Montessori education at Wheaton Montessori School is to help children view knowledge not as isolated subjects, but as valuable gifts passed down from earlier generations. When children pick up a ruler, explore angles with a protractor, or classify triangles in the classroom, they are continuing a legacy that began with those early Rope Stretchers, the Harpedonaptai on the banks of the Nile. Through story, students feel connected to the people who shaped our world and to the problems that inspired great ideas. Geometry becomes meaningful, purposeful, and alive, from our preschoolers working with the Geometry Cabinet , to elementary students classifying and measuring angles or using hands-on Pythagorean Theory materials, and all the way through our adolescents. At the adolescent level, geometry moves fully into the real world. Students apply measurement, angles, area, scale, and spatial reasoning through meaningful work across campus, including: Measuring and mapping land for the campus’s Wetland Conservation Area, as well as calculating classroom square footage for recognition and accreditation applications Understanding and applying area, perimeter, scale, and proportion when working with acreage, restoration plans, and campus layouts Designing and situating functional structures such as chicken coops using geometric principles Applying angle classification, measurement, and spatial reasoning through woodworking Using geometry to cut, join, and build accurately, including raised beds, greenhouses, and beehive insulation boxes
