Cambridge Early Years vs Primary: How the Stages Fit Together
Two names, one ladder. Here is how Cambridge Early Years leads into Cambridge Primary, roughly what age sits where, and how to tell which one your child is in.
Word Safari's English track is aligned to this framework, not an official Cambridge product. Always confirm exact stage names and placement with your child's school.
One ladder, two programme names
Cambridge International runs two separate but connected programmes for younger learners: Cambridge Early Years for the years before formal primary schooling, and Cambridge Primary once that begins. A child typically moves from one into the other, not between two competing options.
The confusion for parents usually is not the concept, it is the vocabulary: "Early Years," "Primary," "Stage," and "Year" all show up in different places, sometimes describing roughly the same point on the ladder. Below is a plain-language walk through both.
Expat and international families feel this confusion most acutely, since a move between schools, or between countries, often means translating between Cambridge's own vocabulary and a completely different local system's grade names in the same conversation. A school enrollment form asking for "Year group" and a curriculum document referring to "Stage" can genuinely be describing the same child at the same point, just labeled by two different frameworks that happen to run in parallel.
Roughly where each stage sits
Exact ages and stage boundaries are set by Cambridge International and by each individual school, so treat the ranges below as a general orientation, not a fixed rule for your child.
- Cambridge Early Years Roughly ages 3 to 5, before formal primary schooling begins.
- Reception (Cambridge Early Years B) The final Early Years step, right before Primary starts.
- Year 1 to Year 5 (Cambridge Primary Stages 1 to 5) The main primary stretch, one stage per school year.
- Year 6 (Cambridge Primary Stage 6) The final primary year, where Cambridge Primary Checkpoint sits.
A parent's simplest test: if your child's school still calls it "Reception," "Pre-K," or an Early Years class, they are most likely still in Cambridge Early Years. Once a school starts using "Year 1" or "Stage 1," Cambridge Primary has begun.
What actually changes as a child climbs the ladder
In broad terms, the earliest stages focus on oral language, letter and sound recognition, and simple decodable words, with reading taught alongside a lot of structured play. Moving through the Primary stages, a child meets more letter combinations, longer and less predictable words, and eventually full independent reading of chapter-length texts, with comprehension and writing becoming as central as decoding by the later stages.
The exact skills expected at each individual stage are set out in Cambridge International's own published curriculum frameworks, which are the authoritative source if you need the precise learning objectives for a specific stage rather than a general shape of the progression.
None of this requires enrollment in a Cambridge school to be useful at home. Homeschooling families and families supplementing a non-Cambridge school both use the same stage names purely as a shared, well-documented reference ladder, since it is more thoroughly described in public materials than most national curricula and gives a consistent way to talk about progress regardless of which country a family happens to be living in that year.
What each programme is actually for
Cambridge Early Years
Foundational play-based learning: early sounds, letter recognition, number sense, and the groundwork skills formal reading and maths are built on. Less formal testing, more structured play.
Cambridge Primary
Six school-year stages of formal subject learning in English, maths, and science, with optional Cambridge Primary Checkpoint tests along the way to benchmark progress against the framework.
Neither programme is "harder" or "better," they simply cover different years of a child's education, with Cambridge Primary building directly on what Cambridge Early Years starts.
A useful way to think about the handoff: Cambridge Early Years is building the raw materials a reader needs, sounds, letters, attention, a love of stories, while Cambridge Primary is where those materials get assembled into an actual, independent reading skill, subject by subject, across a full school year at a time.
Where Word Safari's practice lines up
Word Safari's English content spans the same ladder, ages 4 to 11, across 7 phonics tiers built from 73 letter sounds and 1,347 words. A short placement round finds where a child sits on that ladder in a couple of minutes, rather than assuming by age or by school stage alone.
If your child is still in the earliest stretch, see our Cambridge Early Years practice app page. Moving into Year 1, our Cambridge Primary Stage 1 practice app page covers what changes at that step. For the full arc from Reception through Year 6 in one place, see Cambridge Primary English at home.
One practical benefit of practicing against the same named ladder a school already uses: a parent does not have to guess whether "getting better at reading" at home is actually keeping pace with what a classroom expects. A placement result expressed against a familiar stage name gives you a shared reference point with a teacher, rather than two separate, incompatible ways of describing the same child's progress.

Questions parents ask
Is Cambridge Early Years part of Cambridge Primary?
No, they are two separate Cambridge International programmes. Cambridge Early Years covers the years before Primary starts, and a school moves a child into Cambridge Primary Stage 1 once that foundation is in place.
What age does Cambridge Primary Stage 1 usually start?
Roughly age 5 to 6, broadly comparable to Year 1 in the England school system, though exact placement is always the school's call and varies by country and by child.
Does my child need to finish every stage in order?
Within a school following the framework, yes, the stages are sequential. For at-home practice, Word Safari places a child by an actual placement round rather than by which stage they are nominally in, so a session can start slightly ahead or behind a school stage if that is where a child genuinely is.
Is Word Safari's stage naming official Cambridge terminology?
Word Safari's content is aligned to the Cambridge early-years and primary framework, not an official Cambridge product. For the exact, current stage names and structure, always check Cambridge International's own published materials.
How do Cambridge stages compare to my home country's school grades?
Broadly, Cambridge Primary Stages 1 to 6 line up with Year 1 to Year 6 in the England system, but exact grade-to-stage mapping varies by country and by school. If you are moving between systems, ask the receiving school directly rather than assuming a fixed conversion.
