What Are Checking & Error Checking Tests?

Error or data checking tests are a common tool for many employers. Being able to quickly identify errors is about more than making certain corporate memos are written correctly.  Error checking helps ensure that people are hired who are capable of:

  • Identifying scam emails, which typically have very similar addresses to real businesses.
  • Making sure numbers are written accurately so that a company doesn’t lose thousands of dollars.
  • Keeping accurate records.
  • Accurately pricing items.

If you are applying for a job that requires a great deal of attention to detail, it is very likely that you will be given an error checking test. Administrative assistants, retail workers, marketing professionals, copywriters, may all be required to take error checking tests.


Taking the Error Checking Test

There are several different test providers who produce error checking tests. Saville and SHL are two of the most notable. There are several styles of tests, and they are all timed. The time allotted and the number of questions on the tests will vary by test provider and the company that is giving the test. Error checking tests usually give you a piece of text or a group of numbers and have you compare the possible answers to either find the one that matches exactly or find the one that doesn’t fit.
