Accessibility test digest
Synopsis
Page: Virtual Science Teachers
URL: https://www.virtualscienceteachers.com/
Score: 447
Tested by: Testaro, procedure tp16
Scored by: Testilo, procedure sp16a
Digested by: Testilo, procedure dp16a
Introduction
The Testaro application used its tp16 testing procedure to test the accessibility (barrier-free design and coding) of the Virtual Science Teachers web page at https://www.virtualscienceteachers.com/ on 2022/10/02. The procedure performed 1229 tests. Of these, 23 are custom tests or quasi-tests
by Testaro, and the others belong to these eight other packages (programs that perform collections of tests):
- Alfa by Siteimprove
- Axe-core by Deque
- Continuum by Level Access
- HTML CodeSniffer by Squiz Labs
- Equal Access by IBM
- Nu Html Checker
- Tenon by Level Access
- WAVE by WebAIM
Testaro produced a report enumerating the test results.
Testilo processed the report and used the sp16a scoring procedure to compute partial and total scores for the page. The total score is 447 (where 0 is the best possible score). The scored report is appended below.
Finally, Testilo used procedure dp16a to produce this digest, briefly explaining how sp16a computed the scores.

Discussion
Although there are widely accepted accessibility standards, there is no unanimity about how to define, test, and quantify accessibility. The failures reported in this digest merit investigation as potential opportunities for improved accessibility. Investigation may lead you to conclude that some of the reported failures do not actually harm accessibility. Conversely, some substantial accessibility faults can escape detection by any of these tests. You may question the attempt to assign an accessibility score to a web page, or you may prefer weightings and formulas different from those used by sp16a. You can modify and extend Testaro and Testilo to fit other theories and priorities.
Here, in brief, is how sp16a computes a score for a page.
- It finds all the defects and warnings (let’s call them
issues
) recorded in the report. - It classifies them according to type. For example, a link that looks like the text around it is one issue category, while a video that has no captions is another issue category.
- It also classifies the issues according to severity. For example, an issue that prevents a transaction is more severe than an issue that only complicates the transaction, and a warning about a possible issue is less severe than a definite finding of an issue. (Some packages rate the severity of each issue; for the other packages,
sp16aassigns a severity weight to the issue type and uses that weight.) - It assigns quality ratings to particular tests that are judged abnormally reliable or unreliable.
- It assigns a score to each issue reported by each test of each package.
- It aggregates the issue scores, weighting them by severity, test quality, and redundancy. Redundancy occurs, and causes downweighting, when two or more packages contain tests that are designed to discover the same or mostly the same issues. So the score for a category is not simply the sum of the scores of the tests in that category.
- It assigns a score for issues in the page logged by the browser.
- It assigns an estimated score each time the page prevents one of the packages or one of the Testaro tests from being run on the page.
- It adds the scores together to obtain a total score.
The precise rules of sp16a are found in the code itself.
