A preschool portfolio is a curated collection of evidence about one child's learning over time: dated work samples, photographs of projects and play, selected observation notes and learning stories, recordings of the child's talk, and pieces the child chose herself, each with a short note on why it matters. A good portfolio is selective rather than exhaustive, shows change across the year, and is reviewed regularly with the child and the family.
Portfolios are one of the most visible parts of assessment without scores. They are what families hold in their hands at a progress conversation, what a child flicks through with pride, and what a new teacher reads to get to know a child quickly. They are also easy to get wrong, either by turning into a bulging folder of every drawing the child ever made or by becoming a polished showcase with nothing in it a teacher can actually use. This article explains what belongs in a portfolio, how to curate it with children, and how to choose between paper and digital formats.
What a portfolio is for
A portfolio has three jobs. It shows learning over time, which no single observation can do. A drawing of a person made in September next to one made in March tells a family more about their child's development than any description. It gives the child a voice in her own assessment, because children can choose pieces, explain them and see their own growth. And it supports communication, between teachers and families, between this year's teacher and next year's, and between preschool and primary school.
Each job shapes what goes in. To show learning over time, the portfolio needs dated samples of similar kinds of work collected at intervals. To give the child a voice, it needs pieces the child selected and her own comments on them. To support communication, it needs short teacher notes that explain what each item shows, because a painting without context is just a painting.
It also has a fourth, quieter job: it keeps the adults honest. When a teacher sits down to choose evidence for each child and finds that one child's section is thin, or that every item comes from the art table and none from the garden or the block corner, she has learned something about where her own attention has been. The portfolio reflects the teaching as much as the child.
A portfolio is not a storage box. Most children produce far more work than any portfolio can hold, and most of it should go home, be displayed or be recycled. The portfolio holds the pieces that tell the story.
What to include
Different schools use different structures. The list below works well for a bilingual preschool and fits the six dimensions of the Global Nexus curriculum, but the categories overlap and a single item often belongs in several.
| Item | Why it belongs | How often |
|---|---|---|
| Self-portrait or drawing of a person | Shows fine motor control, observation and representation changing over the year | Once each term, same prompt |
| Mark-making and early writing | Shows the move from scribbles to letter-like shapes to name writing | Every few months |
| Photographs of constructions and projects | Captures three-dimensional work and group projects that cannot be stored | During each theme |
| Audio or video of the child talking | Records spoken language in Vietnamese and English, which writing cannot show | Once or twice a term |
| Selected observation notes and learning stories | Explain significant episodes in context | As they are written |
| Child-chosen pieces with the child's comment | Gives the child ownership and shows what she values | At regular review times |
| Family contributions | Adds what the child does at home and in the community | Whenever families offer them |
The repeated items, such as the termly self-portrait, are the backbone of the portfolio. Because the prompt is the same each time, the change between them is easy to see, and children are often fascinated by their own earlier drawings.
Curating with children
Children as young as three can take part in choosing what goes into their portfolio. The simplest method is a regular review time, perhaps at the end of each theme, when a teacher sits with a child and a small selection of recent work and asks which piece she would like to keep and why. The child's answer is written down, in her own words and in the language she used, on a small card attached to the piece.
The answers are often surprising. A child may choose a painting the teacher thought unremarkable because she remembers mixing a colour for the first time, or reject a careful drawing because she did not enjoy making it. These choices tell teachers what children value about their own learning, which is information worth having.
Older preschoolers can also review the whole portfolio, turning back through the year and talking about how they have changed. Questions such as what can you do now that you could not do before, or which piece are you proudest of, help children reflect without turning reflection into a test. The aim is for the child to see herself as someone who learns and grows, not to rate her own work.
Teachers should resist the temptation to fill the portfolio with only the most impressive pieces. A portfolio that shows a struggle, a half-finished attempt and then a breakthrough is more honest and more useful than a gallery of successes.
Paper or digital?
Many schools now keep portfolios digitally, often through an app or a shared drive. Others keep paper folders or books. Each format has real strengths, and many schools combine them.
| Paper portfolio | Digital portfolio | |
|---|---|---|
| Strengths | Children can hold and browse it independently; original work is preserved; no screen needed | Holds audio and video; easy to share with families abroad; does not fill shelves |
| Weaknesses | Bulky; easily damaged by humidity; hard to share with families who travel | Children rarely browse it on their own; depends on a platform; images raise privacy questions |
| Works best for | Younger children, child-led review, end-of-year keepsake | Spoken language, projects, families who live between countries |
| Watch out for | Storage in a humid climate; loss when children change rooms | Overloading with photographs; unclear rules on who can see what |
A common compromise is a slim paper book that the child can handle, holding the key pieces and the child's own choices, alongside a digital record that holds recordings, extra photographs and teacher notes. Whatever the format, the school needs a clear policy on where children's images are stored, who has access and what happens to the portfolio when the child leaves.
Portfolios for babies and toddlers
Portfolios for children under three look different, but they are no less valuable. Very young children produce little that can be filed, so the portfolio relies more on photographs, short video clips and teacher notes: the first time a baby rolled over on the mat, a toddler stacking three cups, a sequence showing a child learning to feed herself with a spoon. Each item still needs a date and a sentence explaining what it shows.
For this age group the portfolio is often as much for the family as for the teachers. Parents of infants and toddlers miss a great deal of their child's day, and a portfolio that shows how their child explores, communicates and settles in care helps them feel connected. It also helps the transition when a child moves from the toddler room to a kindergarten class, because the new teacher can see at a glance what the child enjoys and how she likes to be comforted.
Teachers should take particular care with privacy here. Photographs of very young children during nappy changes, bathing or sleep do not belong in any portfolio, and images should focus on activity and interaction rather than on the child posed for the camera.
Common portfolio problems and how to fix them
The folder that keeps growing. If everything goes in, nothing stands out. Agree as a team on the core items for each term and send the rest home. A thinner portfolio with clear notes is far more useful than a thick one with none.
Pieces without dates or context. An undated drawing cannot show change over time. Build the habit of writing the date and one sentence on the back of every piece as it is selected, rather than trying to reconstruct it at the end of term.
Teacher-chosen showcases. When only the adults choose, portfolios drift toward the neatest work. Make sure each review includes at least one piece the child chose, with her own explanation.
Portfolios that sit on a shelf. A portfolio no one opens between progress meetings is not doing its job. Leave paper portfolios where children can reach them, and build a short review into the end of each theme.
Using the portfolio with families
The portfolio is the natural centre of a progress conversation with a family. Rather than reading out a report, the teacher can open the portfolio with the parents, show the termly self-portraits side by side, play a short recording of the child telling a story in English, and explain what the teachers have noticed. Parents can see the evidence for themselves, ask questions and add what they know from home.
Families should also be able to contribute to the portfolio throughout the year. A photograph of a child helping to cook at home, a drawing made at the weekend or a note about a new word in Vietnamese all belong. In a school that serves Vietnamese and international families, contributions in either language are welcome, and teachers can help translate key comments for co-teachers.
One rule is worth stating clearly to families: portfolios are not for comparison. Each child's portfolio describes that child's own journey. Teachers should never show one child's work to another family as an example of where their child should be, and families should be gently discouraged from comparing portfolios at the school gate.
The portfolio at the end of preschool
At the end of the final preschool year, the portfolio becomes a bridge to primary school. In Vietnam most children start primary school in the year they turn six, and the move is a big one: larger classes, more sitting, more formal instruction. A portfolio that shows a child's interests, strengths and ways of learning can help families talk to the new school, and it reminds the child that she arrives with a history of learning, not as a blank page.
Most schools return the paper portfolio to the family as a keepsake. Digital records should be handled according to the school's data policy: families should be told how long they will be kept, how they can download them and when they will be deleted.
In the Global Nexus curriculum, portfolios are organised so that the six dimensions of development, language, emotion, life skills, independence, creativity and thinking, are all represented, and they sit alongside the individual development record that summarises progress against the national preschool programme. The portfolio shows; the record summarises. Used together, they give families both the detail and the overview.
Câu hỏi thường gặp
How many items should a preschool portfolio contain?
There is no fixed number, but selective is better than exhaustive. A few carefully chosen pieces per theme, plus repeated samples such as a termly self-portrait and the child's own choices, usually tell the story of a year clearly.
Can very young children choose what goes in their portfolio?
Yes. From about three years old many children can pick a favourite piece and say something about it. With toddlers, teachers can notice what children return to or point at, and record that as the child's choice.
Should every piece in the portfolio have a teacher note?
Most pieces benefit from a short note saying when it was made, what the child said about it and what it shows. Without context, families and future teachers cannot tell why the piece was chosen or what learning it represents.
Is a digital portfolio app necessary?
No. Apps make sharing easier, especially for families who travel, but a paper book and a simple shared folder work well. The quality of selection and notes matters far more than the platform.
Who owns the portfolio at the end of the year?
Most schools give the paper portfolio to the family as a keepsake. Digital records should follow the school's data policy, and families should know how to download them and when they will be deleted.
How does a portfolio help with the move to primary school?
It gives families concrete examples of their child's interests and strengths to share with the new school, and it helps the child see herself as an experienced learner starting a new chapter.
