What and how do we measure?

In the interest of transparency we list the exact tools and calculations so that the data is as reproducible as possible.
Tři čísla v různě barevných kruzích – zelený, červený a oranžový. Ukazující výpočet Index CSGOV Score.
Index CSGOV evaluates public administration websites in two areas: accessibility and performance. Combining both metrics produces the overall ICS score (Index CSGOV Score).

Combined score (ICS)

The Index CSGOV Score is the average of the accessibility and performance scores:

ICS = (accessibility + performance) / 2

If only one score is available, it is used as the result.

Limitations of automated testing

Automated tools catch roughly 25–30% of accessibility issues. A high score therefore does not guarantee a flawless website — we always recommend complementing it with a manual audit and testing with real users.

Performance measurement methodology
The performance score expresses how fast a website loads and responds to user interactions.

Note

A test may not always run successfully — for example if the target website uses strong anti-bot protection, is unavailable, or blocks automated requests. In that case no results are displayed.
