Methodology

The Sonde Score is a universal 0–1000 compliance index — think of it like a credit score for accessibility. Each finding is weighted by its impact on human access: a keyboard trap (critical) counts far more than a best-practice suggestion (low). The raw penalty is normalized per page so scores are comparable across sites of any size. A harmonic curve ensures every site gets a meaningful score — no zeros, no false perfection.

Score = round(1000 × S / (S + P/N))

where S = sensitivity (750), P = Σ(weight × count), N = pages scanned

Tier	Weight	Examples
Critical	10	Keyboard traps, missing page language
High	3	Missing alt text, insufficient contrast
Medium	1	Heading hierarchy, unclear link purpose
Low	0.25	Best-practice suggestions

The Sonde Score is a living standard (v0.1). We publish the methodology and invite public feedback because accessibility is too important for closed-door decisions. Your expertise makes it better.
