Charitable accessibility 2022, test results

Introduction

The table below compares 38 web pages on accessibility. The pages are the home pages of the charities that received the best scores in a preliminary round of testing. The charity names in the first column are links to the tested pages on the web. The scores in the second column are links to digests that explain in detail how the scores were computed.

The pages were:

1. Tested by Testaro with procedure tp16
2. Scored by Testilo with procedure sp16a
3. Digested by Testilo with procedure dp16a
4. Compared by Testilo with procedure cp16a

The Testaro procedure performed 1225 tests on each page. Of these, 19 tests were custom tests defined by Testaro, and the others belonged to packages of tests created by others.

Comparison

Discussion

The charities named above, compared with other charities, have home pages that pose relatively minor barriers to users, including users with disabilities, but the test results suggest that in all cases some accessibility deficiencies remain.

Caveats: The tests assign scores even for suspected accessibility issues, so a score of 0 is not to be expected. Moreover, even a large battery of accessibility tests is fallible and subjective. Any scoring formula is, too. The faults reported in the digests merit investigation as potential opportunities for improved accessibility. Some may not actually harm accessibility, and some other accessibility faults are not detectable with these tests. Different reasonable procedures could yield different test results and different scores. Testaro and Testilo can be customized to fit different definitions and weightings of types of accessibility.
