Error Checking Tests
What are error checking tests?
Error checking tests assess a candidate’s ability to identify errors in data sets and assess the correctness of information. They are also known as Data checking tests. Candidates are required to complete error checking tests under timed test conditions.
In the example below, compare the blue code and say whether it appears on the left or not:
How to prepare for an error checking test?
The best way to prepare is to do good quality question practice. The error checking tests below have been developed by Chartered Occupational Psychologists who are the professionals who develop the test publisher psychometric tests
You can also improve your error checking abilities by:
-
Reviewing your own work for errors e.g. self-reviewing emails you write.
-
Reviewing a colleague or friend’s work e.g. an essay.
The main challenge of error checking tests is the limited time you have to complete each question.
This is why it’s very important that you practice timed error checking tests and get used to working quickly and accurately while under time pressure.
Who uses error-checking tests?
Candidates applying for the following roles may be asked to take error checking tests:
-

How are error checking tests scored?
Error checking tests evaluate a person’s ability to find errors in data sets. You will have to identify deviations in a series of data sets to pass the test. The amount of correctly identified sets in the allotted time will form your score.
What are error checking tests used for?
Error checking tests are used to evaluate how well and fast you can find flaws in data sets. These sets may consist of code or alphanumeric blocks. How well you do depends on your attention to detail and thoroughness when analysing information.
What do error checking tests involve?
Error checking tests involve so-called “strings” of data that might have flaws in them. Test takers will have to quickly identify whether these data sets are the same or not. Promptness is a crucial part of these tests and will have as much weight for your score as the number of correctly identified deviations.
What do error checking tests measure?
Error checking tests assess how well a person can find deviations in certain data sets. The questions themselves aren't typically hard, but there will like be a large number of questions in a short time period so your ability to work under pressure will be revealed.
Where can I practice error checking tests?
Error checking tests require a sharp eye. The best way to train this skill is a consistent practice. You can find top-notch tests of varying difficulty on our website. They are designed to help you master error checking in exam-like conditions alongside tips and guides.
Which employers use error checking tests?
Error checking tests assess how well and how fast a person can work with data sets. Therefore, you will often find them in operational (call centers, invoice management, engineering), administrative (business support roles, personal assistants) & customer service (commercial sales, customer support) roles.
Error checking test tips
1Question practice is paramount
There is no substitute for spending time practicing good quality Error Checking Test questions. The real Error Checking Tests developed by test publishers are typically written by Chartered Occupational Psychologists so make sure the questions you are practicing questions that have also been written by Chartered Occupational Psychologists.
2Practice under exam conditions
This means practicing questions in a quiet environment and preferably at a desk with rough working paper. Psychometric tests are stressful and the more you simulate exam conditions the calmer you are likely to be during your real assessment. Making sure that you practice questions under timed conditions is also exceptionally important because your real assessment will be timed and this is the main challenge i.e. working quickly but accurately while under time pressure.
3Make a revision timetable
Prior preparation a planning is essential to success. This means mapping out how many days you have before your real assessment and planning your revision time. Often graduate employers give you a window in which to complete your psychometric test, however, it’s worth bearing in mind that they often recruit on a first come first served basis so while it’s important not to rush into sitting your psychometric test before you are ready it’s best not to drag out your application process.
4Review the questions you get incorrect
After completing a error checking practice test make sure you spend sufficient time reviewing the questions you did not get correct. You will learn a lot from reviewing these questions.
5Read the instructions carefully
It’s often tempting to dive straight into a psychometric test in order to get it over with but it is very important you read all the instructions first. The instructions will give you invaluable pieces of information e.g. how many questions you will be asked to answer and how long the test will last. If you know this you can and must work out how long you have to answer each question. It’s important you move on if you get stuck, easier questions may follow and if you’ve read the instructions carefully they should tell you whether you can go back and attempt difficult questions you passed later having tackled the easy ones.
6Don’t panic
Panicking is not helpful during a psychometric test, however, it’s easy to do. If you have spent sufficient time practicing questions under timed exam conditions then this should relieve a lot of the anxiety you would otherwise experience as the exam timer starts. Make sure you get a good night’s sleep before you real assessment and ensure you’re hydrated.
7Don’t get your friends to help you with your real assessment
Employers often retest candidates at assessment centres so it’s simply not worth getting a friend or family member to complete an Error Checking Test for you.
8Timing is key to success
Error Checking Tests are challenging because they require candidates to complete them under strict time constraints. Test publisher tests typically allow candidates between 15 and 30 seconds to answer each question, you must get used to working quickly and accurately under this sort of time pressure.
9Complete the test publisher practice questions
After reading the instructions you will be presented with some example questions prior to your real assessment starting. These practice questions are typically not timed so take your time reviewing the format of the test publisher test. Take note of where the timer is on the screen, what format the questions are in and where the possible solutions are displayed on the screen.
10Practice is they key to success
This is repetition of point 1 above but if you take nothing else from the advice above remember that question practice is the best way to improve your test scores.
