Group Bourdon Test Online - Bourdon-Wiersma Test

The group Bourdon test, or rather a variation of it - the Bourdon-Wiersma test, or the dot cancellation test, will allow you to assess the possibilities of your attention, including the efficiency of attention and the accuracy of attention.

Here you can pass the Bourdon-Wiersma Group test online for free and find out the main possibilities of your attention. Note: it will take 1 second to prepare the table by the server and calculate the result. For devices with a small screen size, there is a table for 16 groups of dots in a row instead of 25. Keep in mind that you need to fill in the cells sequentially - from left to right, first the top line, and only then the line below, otherwise the result will be distorted.

Instructions for the Group Bourdon test:

By clicking on the link for passing the test, you will be taken to a page with several rows of pictures with dots. Each picture contains 3, 4 or 5 points. Your task is to select as many pictures with four dots on five tables as possible. It takes two minutes to select groups of points in each table, after two minutes you will be forcibly redirected to the page with the next rows of points, and so on until the 5th page, until finally you go to the page with the results. Try to take the test carefully, and then your results will be more objective and accurate.

Group Bourdon test (Dot cancellation test). The total time to complete the test is 10 minutes. Time to complete one table is 2 minutes.

Group Bourdon test - dot cancellation test:

The dot cancellation test is essentially a type of Bourdon test, or rather the Bourdon-Wiersma test

Main factors:

Processing speed (V) is calculated by the formula: V = N/c , Where N is the number of characters processed, and t is the number of minutes.
Processing accuracy (K) is calculated using the formula: K = (N-A) / N , where A is the average number of errors.
Almost anyone can assess the ability of their attention, but this test option is more suitable for adults, since it can be tedious for adolescents and young children. Keep in mind that the result does not show accurate data on the capabilities of your attention, since today there are no sufficiently accurate methods of checking attention using the Bourdon test online. For more accurate results, you can take a professional test on paper using proven methods.

When clicking to get the test results, it is just presenting blank answer sheet without the specific results from the test taken.

Admin 2025-09-18 06:08:49

sagar, unfortunately, modifying this Bourdon-Wiersma test to suit your request is somewhat challenging, but we will try to add this functionality in the future. Ian, to receive results for this test, you must complete all five forms sequentially. Once you`ve completed all five test pages, which will take 10 minutes — two minutes per page — you`ll be taken to the results page. Importantly, you can only receive results if you reach the minimum number of correct answers.

Hi do you have a pdf version of this assessment you could email me please I have not been able to locate one for post stroke driving ax. thanks

Admin 2025-10-20 10:32:37

Hello, Alana. Unfortunately, our website currently doesn`t offer the option to generate test results in PDF format. However, you can save your results—the basic data from your Bourdon-Wiersma test—using a prepared test certificate. After completing the test, below the results section, there`s a link to your certificate. You can save it to your computer to view your previous test results. Just today, we fixed a bug that prevented the certificate from displaying data; this issue has now been resolved.

Is there an app or just the website?

Admin 2025-11-05 22:20:19

Jonathan, hello. Currently, only the web version of the test is available, primarily because completing it on a computer is more reminiscent of the real-life professional testing conditions. If you have internet access, you can easily take the mobile version of the Bourdon-Wiersma test using this website.
