Find your child's actual math level in 10 minutes

Adaptive placement across counting through pre-algebra, built by a homeschool parent. No account, no email, no curriculum lock-in. Just a clear picture of where your child is and where to start.

How old is your child?

No account needed. Results are yours.

~10 minutes

15-30 questions; the test ends as soon as it finds a level.

No account needed

Take it, see results, walk away. Or sign up to keep going.

Per-skill breakdown

Strengths, gaps, and a clear starting point — not just a grade level.

What you'll see at the end

Most placement tests give you a single number. This one gives you a per-skill picture so you can act on the result.

Estimated level

A specific grade equivalent — not just "3rd grade" but "Early 3rd Grade" or "3rd Grade or higher" if your child cleared the ceiling.

Strengths

Every skill your child passed in the test, plus skills we infer they know based on grade-level pass rate (clearly labeled as inferred).

Gaps

The specific skills your child struggled with, named clearly (place value, fraction addition, two-step word problems, etc.).

Starting point

If you sign up, this is exactly where Lumastery picks up — no second placement test, no lost time.

What this test is — and what it isn't

It is

  • An adaptive starting-point finder for K-8 math
  • Honest about what it tested and what it inferred
  • Free to take and free to retake
  • Built to find a level fast — most kids finish in 10 minutes

It isn't

  • ·A diagnostic that maps every skill — that's what daily practice does
  • ·An IQ test or a standardized achievement test
  • ·A verdict — kids have off days; you can retake
  • ·A sales funnel — results are yours whether or not you sign up

How the adaptive engine works

  1. 1

    Starts at your child's expected level for their age

    A 7-year-old begins around early 1st-grade content, not at counting. A 10-year-old begins around 4th grade. The test never asks every K skill of an older kid.

  2. 2

    Tests skill by skill, not just grade by grade

    Each skill (place value, multi-digit multiplication, fractions, etc.) gets a few questions. Pass it, advance. Struggle, step back to the prerequisite.

  3. 3

    Skips ahead when a skill is clearly mastered

    If your child gets the first two questions in a skill right, the test moves on instead of forcing five reps. That's how it covers ground in 10 minutes.

  4. 4

    Caps the ceiling so a lucky cascade doesn't mis-place

    The test won't pin a 7-year-old at 5th grade because they got two G2 questions right. The ceiling stays at one grade above expected — enough headroom to demonstrate readiness, not enough to overshoot.

How this compares to other placement tests

Most homeschool math placements are PDFs from a specific curriculum that you grade yourself. They tell you which book to buy. This test does something different.

Common questions

How long does the placement test take?+

About 10 minutes for most kids. Younger children (K and early 1st) get a shorter version of around 15 questions; older children answer up to 30. The test ends as soon as we have a confident read, which is often before the maximum.

What grades does this cover?+

Kindergarten through 8th grade. The test starts at your child's expected level for their age and adjusts up or down based on their answers, so a 7-year-old who is advanced still gets a chance to show 4th-grade work, and an 11-year-old who is behind can land at the level they actually need.

Is this really free? What's the catch?+

The placement test is free, no account required. We're a small homeschool-built platform, and the test exists to help you place your child correctly whether or not you ever sign up. If you do sign up after, the test results carry over and Lumastery picks up exactly where the placement left off.

What if my child has a bad day?+

A 10-minute test can't see everything. If your child is tired, distracted, or guesses on a few questions they actually know, the test may underestimate by a level. The good news: you can retake it any time, and once your child starts using Lumastery, the daily engine refines the placement automatically — confirming what they truly know and surfacing any skill that needs more work.

Will the test stress out my child?+

It's designed to feel like a friendly quiz, not a high-stakes exam. Questions adapt — if a skill is too hard, the test backs off rather than continuing to ask harder questions. There's an "I don't know" button on every question, and there's no time limit. Most parents sit with younger children and read questions aloud.

How does the adaptive part work?+

The test groups questions by skill (counting, place value, multiplication facts, fractions, and so on). It starts at the skill expected for your child's age. If your child gets a skill's questions right, the test advances. If they struggle, it steps back. Within a single skill, getting the first few right early ends that skill quickly so the test can spend the question budget exploring more skills.

How is this different from a Singapore Math, Saxon, or Math Mammoth placement test?+

Curriculum-specific placements (Singapore, Saxon, Math Mammoth) are downloadable PDFs you administer, score, and interpret yourself. Useful, but they tell you which book to start with — they don't tell you which specific skills your child knows and which need work. This test is online, adaptive, and gives you a per-skill breakdown plus a starting point in our adaptive curriculum if you want one.

My child is way behind / way ahead. Will this still work?+

Yes. The test is designed to find a ceiling and floor for any child K-8. If everything is hard, it surfaces foundational skills as the starting point. If everything is easy, it keeps stretching upward until it finds something challenging. There's no "you're too far behind" or "you're too far ahead" outcome.

Can siblings share the same test, or do they each take their own?+

Each child should take their own. The test is short enough that sharing isn't worth it — you'd miss the per-child placement which is the whole point. If they're close in age, you'll see how their actual skills differ.
