Uchida-Kraepelin Test: Assess Your Work Capacity and Attention

This test is a standardized introductory version of the Uchida-Kraepelin test, which has gained popularity in Japan and other countries as one of the primary tests for professional selection of job applicants. The test measures subjects' attention abilities, mental performance, and fatigue based on the number of solved examples within a time limit. The test consists of a table with 15 rows of numbers (in our version - 60 numbers and accordingly 59 examples of adding left and right numbers) with 1 minute allocated for each row in the standard version, and two tables with 15 rows of numbers in the advanced version (with a 15-minute break between tables). The subject's task is to add the first digit to the second, the second to the third, and so on, entering the result in the input fields between the numbers, doing this as quickly as possible. Our Uchida-Kraepelin test is an introductory version and does not claim accuracy since it cannot be conducted under controlled and standardized conditions. It is free and adapted for most devices - computers and smartphones. For more accurate results, we recommend taking the professional version of the test.

Please note: If you are taking the advanced version of the Uchida-Kraepelin test, to get the results after taking the first series of the test, you need to wait 15 minutes and take the second series of the test, only then will you get to the test results. If the advanced version is not suitable for you due to the large amount of time required to complete it, choose the regular version of the test with one table.
