Rank scores. Track growth. Upload or enter exam results to rank students by percentile, then use the WHO-based calculator to screen a child's anthropometric measurements against age- and sex-specific growth standards.
Add students
Upload a CSV or Excel file, paste a list, or add students one at a time — there's no cap on roster size, so this works just as well for a class of 20 or a school of 2,000.

First row should be headers — something like "Name" and "Score" (out of any max; you'll confirm below).
One student per line. Works with "Name, Score", a pasted Excel/Sheets selection (tab-separated), or "Name Score".
Rankings
Percentile = the share of classmates this score is at or above. Rank 1 is the top score; tied scores share a rank.

Screening tool, not a diagnosis. Percentiles here are calculated from WHO Child Growth Standards (0–5y) and WHO Growth Reference (5–19y) median and spread values, sampled at standard checkpoint ages and interpolated between them — they closely track but won't bit-for-bit match the official WHO Anthro software's exact tables. For clinical decisions, confirm against official WHO charts or a healthcare provider.
Add a measurement
Enter one child's details to get a centile and a normal / abnormal flag based on WHO reference cut-offs (±2 SD, ±3 SD).
Weight-for-height/length is based on body size, not age — no age needed for this one.
