Marta has a son who will turn six next year. From friends she hears conflicting things: that zerówka is compulsory, that it is not, that it has to be done at school, that it can also be done at preschool, that a six-year-old can go straight into first grade. On top of that comes the question that matters most: what will be best for her child.
This article puts that information in order. It explains what zerówka — the Polish “reception year”, sometimes called “year zero” — is under the law, when it applies, where it can be done, how zerówka at preschool differs from zerówka at school, and what the options are if a child is ready for school earlier or needs more time. We base it on the Polish Education Law (Prawo oświatowe) and on the podstawa programowa, the Polish core curriculum for preschool education.
Is zerówka compulsory?
Yes. Under the Education Law, a six-year-old child is obliged to complete one year of preschool preparation — and that is exactly what is commonly called zerówka. The obligation begins at the start of the school year in the calendar year in which the child turns six, and lasts one school year. It can be fulfilled at a preschool, in an oddział przedszkolny — a preschool class in a primary school — or in another form of preschool education.
So zerówka itself is compulsory, but the place where the child does it is not. Parents decide for themselves whether their six-year-old stays at their own preschool or moves to a preschool class in a school. The earlier years of preschool, for children aged three to five, are the child’s right, not an obligation.

From what age is zerówka?
Zerówka begins in the calendar year in which the child turns six, always on 1 September, and lasts one school year. What counts is the year of birth, not the exact birthday, so the timing of zerówka depends solely on the child’s birth year, not on whether they have already turned six on the first day of the school year. A child born in January and a child born in December of the same year start zerówka together on 1 September — even though one of them is then almost six and the other only five years and nine months old.
An example: a child born in 2021 turns six in 2027, so they start zerówka on 1 September 2027, and first grade on 1 September 2028, in the year they turn seven. Preschool education covers children until the end of the school year in the calendar year in which they turn seven, so zerówka is the last preschool year before school.
The age gap within a single birth year can be noticeable at this age. The youngest children in the year group, born in autumn and winter, sometimes need more time with concentration, independence or handling emotions. This is not a problem, just a matter of months of life — it is worth remembering before comparing a child with a classmate who is almost a year older.
Zerówka at preschool or at school?
Both options are equivalent under the law and follow the same core curriculum for preschool education, so a child who did zerówka at preschool and a child who did it at school have the same rights and the same start in first grade. They differ in surroundings, in the rhythm of the day and in who the child spends time with, and the choice depends above all on the child and on the needs of the family.
Zerówka at preschool. The child stays in a familiar place, with familiar adults and often with the same friends. The day usually follows a preschool rhythm: more time for play and movement, meals at preschool, a rest. For children who need predictability, or for whom change is hard, continuity can be a big advantage. In a mixed-age group the six-year-old is the oldest and takes on the role of an older friend, which builds their self-confidence.
Zerówka at school (a preschool class in a primary school). The child gets to know the school building where they will probably start first grade and gets used to bells, corridors and older pupils. The move into first grade can be gentler as a result. At the same time, for some children the school environment is noisier and less cosy, and the day is organised differently than at preschool.
There is no single right answer. It is worth asking yourself a few questions: how does the child cope with change? Do they feel good and develop well at their current preschool? Which school will they go to for first grade, and is the zerówka in that same school? What does the family’s logistics look like — working hours, commuting, siblings? A good step is also a conversation with the teacher, who has known the child for months and sees them in the group, as well as visiting both places together with the child to see where they feel more at ease.
What does a child learn in zerówka?
Zerówka follows the core curriculum for preschool education — the same at a preschool and in a preschool class at a school, public and non-public alike. It is not the first-grade curriculum but a description of readiness for it. It sets out what a child should be able to do at the end of preschool education in four areas of development: physical, emotional, social and cognitive.
In the physical area the focus is above all on independence: personal hygiene, getting dressed including doing up buttons and tying shoelaces, eating with cutlery, laying the table and clearing up, as well as physical fitness and a writing grip. In the emotional area — recognising and naming emotions, separating from parents without fear and being able to wait for one’s turn. In the social area — relationships with peers, polite expressions, knowing one’s own first name, surname and address, and cooperating in a group.
In the cognitive area the core curriculum lists, among other things, clear and fluent speech, distinguishing sounds at the beginning and end of simple words, recognising the letters the child is interested in and reading short words made of familiar letters, counting objects, recognising the digits from 0 to 10 and adding and subtracting in everyday situations, as well as orientation in time and space, for example telling left from right.
Importantly, the core curriculum states explicitly that during preschool education a child does not learn reading and writing together with the whole group, but prepares for them. So zerówka is not “first grade in miniature” but a year of building readiness: a skilful hand, an attentive ear, the ability to concentrate and to cooperate. More on what to expect from a six-year-old can be found in the article on what a 6-year-old should be able to do.
Can a six-year-old go straight into first grade?
Yes. The Education Law allows a child who turns six in the given calendar year to start primary school at the parents’ request. The head teacher admits such a child if they meet one of two conditions: in the school year before starting school they attended preschool education, or they have an opinion on the possibility of starting school issued by a poradnia psychologiczno-pedagogiczna — a psychological and educational counselling centre.
A child admitted to school early is exempt from the zerówka obligation. In practice this means the six-year-old goes to first grade instead of zerówka, not after it.
The decision about starting school earlier is worth making carefully. A child who copes brilliantly with letters and numbers is not always equally ready emotionally and socially: for sitting at a desk, working in a large group, dealing with failure or a longer day without an adult who has known them for years. The opinion of the preschool teacher and a consultation at the counselling centre can be helpful.
Deferring compulsory schooling — when a child stays longer at preschool
If a seven-year-old child is not ready for school, parents can apply to defer the start of compulsory schooling by one school year. The application is submitted to the head teacher of the public primary school in whose catchment area the child lives, in the calendar year in which the child turns seven, no later than 31 August. It must be accompanied by an opinion from a psychological and educational counselling centre showing the need for deferral. The counselling centre — public, or non-public with specialists holding the qualifications required in public centres — assesses the child during meetings with a psychologist and an educational specialist. It is worth booking an appointment well in advance, because in spring and summer the waiting times at counselling centres can be long.
A child whose compulsory schooling has been deferred continues preschool preparation — they stay at preschool or in a preschool class for one more year. Deferral is neither a failure nor a punishment. It is not the preschool or the counselling centre on its own that decides on deferral — the decision is made by the school head teacher at the parents’ request, and the counselling centre’s opinion is a required attachment. Parents who have doubts can therefore first talk to the teacher and the specialists, and only then decide whether to submit the application. For some children an extra year without the pressure of school is the time in which they mature for learning, and afterwards they cope with school much better.
How to prepare a child for zerówka?
The best preparation is not workbooks but everyday life in which the child does a lot on their own and talks a lot with adults. The skills the core curriculum expects at the end of preschool are built at the table, in the bathroom, at the playground and during bedtime reading, not over worksheets. Before zerówka it is worth taking care of a few things:
- independence when dressing, eating and using the toilet,
- knowing their own first name, surname and address,
- reading books aloud every day and talking about them,
- board games that teach waiting for one’s turn and losing,
- plenty of movement outdoors — running, climbing, jumping, cycling,
- activities that develop the hand: modelling, cutting, threading, pouring,
- talking about zerówka without scaring the child about school and without promising rewards.
If the child is changing places — from preschool to a class at a school — it helps to visit the new building beforehand and, if possible, to see the classroom and meet the teacher. The first weeks may require settling in, just like the first year of preschool; more about this process can be found in the article on settling in at preschool.
What to look for when choosing a preschool for zerówka?
If the family is choosing a new preschool, or wondering whether to stay at the current one, it is worth looking at a few specifics. The number of children in the group and the number of adults tell you how much attention each child will get. The rhythm of the day shows how much time there is for free play, movement outdoors and rest, and how much for activities at tables. It is worth asking how the preschool prepares children for school: through worksheets and handwriting patterns, or through everyday independence, conversation, books and working with the hands.
It is also good to ask about cooperation with parents — how often there are conversations about the child’s progress, whether the teacher shares observations, and whether the preschool works with a counselling centre, a speech therapist or a psychologist when the need arises. A visit will tell you the most, though: the atmosphere in the classroom, the way the adults speak to the children, and whether the children look busy with something that genuinely interests them. More about choosing a setting can be found in the article how to choose a preschool.
Zerówka in a Montessori preschool
A Montessori preschool works in a mixed-age group, usually from about three to six years old, so zerówka there is not a separate class but the final year in the same group. The six-year-old is the oldest: they show younger children what working with the materials looks like, help in the cloakroom and resolve disputes. They themselves reach for the most demanding materials — building sentences with the movable alphabet, mathematical operations with the golden beads, maps and nature cards.
Such a year that completes the cycle is particularly important in Montessori education, because the child consolidates everything they have learned before by teaching others. At the same time they follow the same core curriculum as every zerówka. How this translates into later learning in a mainstream school is described in the article on school readiness after Montessori, and how a mixed-age group works is covered in the article on mixed-age groups in Montessori.
FAQ — parents’ questions about zerówka
Is zerówka compulsory for a six-year-old? Yes. The Education Law obliges a six-year-old child to complete one year of preschool preparation. It begins on 1 September in the calendar year in which the child turns six. The exception is a child who, at the parents’ request, has started school earlier.
From what age is zerówka? From the calendar year in which the child turns six. What counts is the year of birth, not the exact date, so some children start zerówka while they are still five. Zerówka lasts one school year, and after it, in the year of the seventh birthday, compulsory schooling begins.
Can zerówka be done at preschool? Yes. The one year of preschool preparation can be completed at a preschool, in a preschool class in a primary school or in another form of preschool education. The same core curriculum applies in each of these forms, so the choice depends on the child and the family’s needs.
Does a five-year-old have to attend preschool? No. Children aged three to five have a right to preschool education, but no obligation — see preschool age in Poland. Only zerówka is compulsory. Even so, preschool before zerówka is for many children a good time to learn independence and life in a group.
Does a child learn to read and write in zerówka? They prepare for it. The core curriculum states that in preschool education a child does not learn reading and writing together with the whole group, but prepares for them: recognises the letters that interest them, reads short words and practises a writing grip. Systematic learning begins in first grade.
What happens if a child is not ready for school? Parents can apply to defer compulsory schooling by one year. The application goes to the head teacher of the catchment-area school by 31 August in the year the child turns seven, together with an opinion from a psychological and educational counselling centre. The child then continues preschool preparation.
In closing
Zerówka is compulsory, but parents have a real choice: preschool or school, zerówka or an earlier first grade, and if needed — an extra year of preparation. The law sets the framework; the decision is best made by looking at the specific child — their independence, emotions and readiness to work in a group — and by talking with the people who know them day to day.
