MeritScores: adaptive computer assessments
Launch an account-less class test — students join with a code and each one gets questions tuned to their level. Answers are computer-scored into a MeritScore: a percentile ability measure that follows the student over time.
No student accounts

Adaptive per student
Difficulty tailors to each child (aims for ~60%).
Practice at home
Per-student practice links, anytime.
What we test: five categories, no surprises
Every MeritScore maps to one of five categories. Here is exactly what each one covers, so teachers and families know what gets asked — and what doesn’t.
Mathematics
From early counting to calculus: number sense, operations, fractions, algebra, geometry, data & probability — aligned to the US curriculum.
Science
Life, physical, and earth science, plus science practice itself: asking questions, designing experiments, and reasoning from evidence.
History / Social Studies
US and world history, government and civics, and the documents, events, and people students are expected to know.
Language Arts
Reading comprehension, vocabulary, grammar and conventions, and literary knowledge — enduring authors, works, and genres.
General Knowledge
Practical life-and-world knowledge — distinct from the academic subjects. Topics grow with level: counting coins at the early levels becomes compound interest and credit at the upper ones. No pop culture, no riddles, no trivia.
Levels, not grades
Questions are organized into Levels 0–13. Every test is adaptive: difficulty tunes to each student, aiming for a fair challenge rather than frustration. A student’s test level is not their school grade.
How we keep it fair
- • Short written answers — no multiple choice, no guessing.
- • Every question is independently reviewed by a second computer system before it is used.
- • No trick questions and no cultural bias; facts must be stable and verifiable.
- • We never train AI on student work.
