How BopLearn Measures Learning

Transparent, fair, and encouraging β€” here's how we track your child's progress

1

BopLearn Performance Index (BPI)

The BPI is a single score from 0 to 2,100that represents your child's overall learning performance across 7 skill areas. Each skill area contributes a maximum of 300 points.

How it's calculated:The BPI uses a weighted average of your child's game performance. Recent sessions count more than older ones (using exponential decay weighting), so the score reflects current ability rather than historical performance.

The 7 skill areas are:

Maths
Number skills, arithmetic
English
Reading, spelling, vocabulary
Memory
Recall and consistency
Speed
Quick thinking and reactions
Problem Solving
Logic and level progression
Attention
Focus and accuracy
Flexibility
Adapting to new challenges

What the score means: A higher BPI indicates stronger performance across more skill areas. The score naturally grows as your child plays more games and improves.

Year Level Equivalence

We map your child's BPI score to an approximate year level based on the New Zealand Curriculum framework. This helps you understand where your child is performing relative to age expectations.

When we say your child is "performing at Year 3 level," it means their scores across games are consistent with what we would expect from a child in Year 3 of primary school.

Year LevelAge RangeBPI Score RangePerformance Level
Year 050 - 300Foundational
Year 15-6300 - 600Developing
Year 26-7600 - 900Progressing
Year 37-8900 - 1200Competent
Year 48-91200 - 1500Proficient
Year 59-101500 - 2100Advanced

Note: These benchmarks are currently simulated based on curriculum expectations. As our user base grows, we will replace these with real cohort data for more accurate comparisons.

Age Comparison

How percentiles work:A percentile tells you how your child compares to others in their age group. If your child is in the "Top 16%," it means they scored higher than 84% of children their age.

Why we compare within age groups: Children develop at vastly different rates. Comparing a 5-year-old to an 8-year-old would be meaningless. We only compare children to peers of the same age to ensure fair and meaningful insights.

Currently using simulated benchmarks based on developmental research. Real cohort data from BopLearn users is coming soon, which will make these comparisons even more accurate.

Our Approach

🌱
Growth mindset
We believe every child can improve. Our scoring system rewards effort and progress, not just natural ability.
🐒
Every child’s pace
Learning isn’t a race. Children develop different skills at different times, and that’s perfectly normal.
πŸŽ‰
Celebrate improvement
Our system highlights when your child improves, not just when they achieve a high score. Getting better matters most.
πŸ”’
Parent-only rankings
We never show rankings or comparisons to children. This data is exclusively for parents to understand where to focus.
πŸ”
Focus, not judgement
Comparison data helps identify where your child might benefit from extra practice. It’s a tool for guidance, not grading.
πŸ’š
Encouragement first
Every interaction with your child through BopLearn is designed to encourage and motivate, never to discourage.
