What Does a Montessori Teacher Do? Duties and Job Description

A Montessori teacher leads a classroom where children choose their own work from a prepared set of hands-on materials.

The job's center of gravity sits in a different place than in a traditional early-childhood room: less of the day leading the whole group, more of it presenting a material to one child or a few, then observing while the child's own repetition does the teaching.

The responsibilities of a Montessori teacher still cover everything any childcare classroom runs on — care routines, supervision, records, family communication — plus the Montessori layer: keeping the environment complete and ordered, giving presentations at the right moment for each child, and tracking what each child has mastered so the next presentation lands.

The title also sits inside school-specific structures.

Montessori schools sit under different training and accreditation bodies — AMS and AMI among them — and the school's affiliation shapes the credential expectations around the job.

AMS does not require teachers at AMS schools to hold an AMS credential, but AMS-accredited schools must have lead teachers who hold Montessori credentials for the ages they teach.

Two postings with the same title can therefore sit behind different qualification bars.

This page is the duty list: the core responsibilities, the day from arrival to pick-up, what belongs to you versus the other adults in the room, a sample job description, and how the duties read on a resume.

For the occupation as a whole — settings, credential routes and the career — the Montessori teacher career guide covers the role end to end.

The work groups into six areas.

Five are the areas any early-childhood classroom runs on; the first is the Montessori-specific one that frames the rest.

• Preparing and maintaining the environment. The shelves, the materials and the room's order are the curriculum's delivery system: materials complete and repaired, arranged by area, and accessible so a child can choose work and put it back without adult help. Resetting and readying the room is daily work, before the children arrive and after they leave.
• Presenting materials. The Montessori lesson is a presentation: introducing a material to one child or a small group, demonstrating it, then stepping back so the child's practice does the teaching. Presentations follow each child's readiness, so the sequence matters — knowing what comes next for a child who has just mastered something.
• Observation. Watching on purpose: what a child chooses, where they stall, when they are ready to move on. In a Montessori room, observation is the input for the next presentation rather than a pause in the work.
• Records. Tracking lessons given and skills practiced and mastered, child by child, plus the daily care notes any classroom keeps — meals, rest, toileting where the room's children still need support — and the progress reports families receive.
• Care routines and supervision. Meals and snacks, outdoor play, rest time, arrival and dismissal — with active supervision indoors and out the whole time. Supervision is the duty underneath the others (see the note in the responsibilities section below on how state licensing rules treat it).
• Family communication. The daily word at drop-off and pick-up, the scheduled conference on progress, and explaining what the Montessori approach asks of children so families can read the classroom's rhythms from the outside.

No area stands alone.

A morning work block is a presentation slot, an observation window, a supervision assignment and a records entry at once — that overlap is what makes the role feel continuous, because you are teaching, watching and recording inside the same stretch of the morning.

Montessori schools set their own schedules — half-day, full-day, school-year or year-round — so the frame varies by school.

Within whatever hours the program runs, the duties arrive in a recognizable order.

Here is how the list above unspools across a day:

• Arrival and greeting. Receive each child, take a quick read of how they arrive — the first observation of the day — and swap a word with the dropping-off adult. Children settle toward their first choices of work as the room fills.
• The morning work block. The heart of a Montessori day: children move through chosen work while you give scheduled presentations, observe, and protect the room's concentration — stepping in for a child who needs a lesson, a redirect or help, and otherwise staying out of the work.
• Care routines alongside the work. Snack and toileting run alongside the block; in rooms built for it, children carry the routine themselves and the teacher's job becomes keeping it available and clean.
• Outdoor play. The same supervision duty in a different room, with the shelves put to rights and the group outside.
• Lunch and rest. Supervise the meal, then nap or quiet time. For the teacher, this is the reset-and-records stretch: observations and care notes written while the morning is fresh, materials readied for the afternoon.
• Afternoon block. A second round of presentations for children who are ready, plus story and group moments the room builds into its afternoon, and the clean-up routines the children join in.
• Pick-up. Hand each child back with a word about their day, pass on the daily reports and flag anything the family should know, then finish resetting the room.
• After the children leave. Material repair and making, planning the next presentations, the ongoing study the credential asks for, and the conferences and family evenings the school schedules.

On a half-day schedule the same sequence compresses into the morning; on a full-day schedule with staggered staff, your shift may start earlier or end later than the children's day, and the duties at the edges are the same ones — set-up, records, environment — rather than new ones.

In a room with more than one adult, everyone shares the care and supervision of the children.

The difference is who owns the plan — and in a Montessori classroom, the lead teacher owns it.

• Lead Montessori teacher. Owns the prepared environment, the presentation sequence for each child, the records and the family relationships — and answers to the director for the classroom as a whole.
• Classroom assistant (Montessori assistant). Carries pieces of the same day under the lead's direction: keeping materials stocked and shelved, supporting supervision, helping children with routines, and protecting the work the lead has presented.
• Aide. Supports the room's routines, clean-up and supervision alongside the lead and assistant, with the least program responsibility in the room.
• Floater. Assigned to no single classroom: covers breaks, transitions and the hours when a room needs an extra pair of hands.
• Director. Runs the program around the room — staffing, enrollment, family policies, the school's relationships with its accrediting and licensing bodies. Those duties are not part of a classroom teacher's list.

Knowing what you are not responsible for is part of reading the job.

Where the school has a cook, the kitchen is the cook's job; admissions and tuition conversations belong to the school's administration, not the classroom.

If a posting folds those into a lead-teacher role, that is a second job and should read like one.

The exact lines between these roles are set two ways: by the school's own job descriptions, and — where the school is a licensed childcare program — by the state's child care licensing rules, which decide how many adults a room needs and who may be counted toward that staffing.

Those rules differ by state.

A posting compresses the duty list into hiring language: a summary, a responsibilities list and a qualifications block.

Here is a sample Montessori teacher job description in that shape, so you can see how the work reads from the hiring side — and map your own experience onto it.

Sample: Montessori teacher — job description

Position summary. We are hiring a Montessori teacher to lead a classroom where children choose their work from a prepared environment.

The role combines individual and small-group presentations matched to each child, careful observation and record-keeping, supervision throughout the day, and regular communication with families about each child's progress.

Responsibilities.

• Prepare and maintain the classroom environment and its materials, indoors and out
• Give individual and small-group presentations following each child's readiness
• Observe children's work and keep records of lessons given and skills mastered
• Keep daily care records — meals, rest, toileting where needed — alongside progress records
• Supervise children throughout the day, indoors and outdoors
• Support meal, rest and clean-up routines as part of the classroom day
• Communicate with families daily and in scheduled progress conferences
• Work with the classroom assistant to keep the prepared environment running
• Follow the school's Montessori curriculum, record-keeping and reporting procedures

Qualifications. Set by the school itself, and — where it operates as a licensed childcare program — by the state's child care licensing rules on top.

Postings name the credential they want, and the names differ: an AMS credential, an AMI diploma or certificate, or a credential from a program accredited by MACTE — the Montessori Accreditation Council for Teacher Education, which accredits Montessori teacher education programs and is recognized by the U.S. Department of Education.

Enrolling in an AMS-affiliated teacher education program requires a bachelor's degree; candidates without one can earn an associate credential at the Infant & Toddler and Early Childhood levels.

The training routes, costs and level choices behind that paragraph are the territory of our how to become a Montessori teacher guide — this page stays on the job itself.

Then hold a real posting against the duty list.

If it is vague on supervision, records or family communication, those are the questions to ask in the interview — the answers tell you how the room is actually run.

Centers drafting a posting of their own will find the employer-side template on our hiring a Montessori teacher guide.

The direct way to put duties on a resume is to mirror the responsibilities list in the posting, in the same words where they are true of you: action verb first, then what you led and for whom.

The duty sections above translate almost one-to-one:

• Prepare and maintain a complete Montessori classroom environment across the curriculum areas
• Give individual and small-group presentations matched to each child's readiness
• Observe and record lessons given and skills mastered, child by child, and report progress to families
• Supervise children through the full day, indoors and outdoors, alongside meal and rest routines
• Communicate with families daily at drop-off and pick-up and in scheduled conferences

Where a number would strengthen a bullet, use your own — how many children you kept records for, how many presentations a morning could hold — and leave it out where you would have to guess.

A resume bullet you cannot defend in an interview is worse than no bullet.

Match the posting's title in your headline.

Montessori postings go out under titles like Montessori teacher, lead teacher and guide, and the same work can sit behind any of the three — the responsibilities list tells you which parts of this page the school is hiring for, so answer in its words.

And do not hide the care half.

Supervision, meals, records and family communication are the job's daily substance alongside the presentations, and a resume that shows both halves reads like someone who has actually run a Montessori room.
