British Army Aptitude Tests

What is the British Army error detection test?

The British Army error detection test is part of the Army Cognitive Test battery, a five-stage aptitude test that all potential soldiers must undertake as part of the assessment centre. It is a computer based test that assesses your ability to quickly and accurately process information and then spot errors.

The error detection test is not a skills-based test, but rather an indication of your memory retention and attention to detail.

The format of the British Army error detection test

The error detection section of the ACT contains questions that are in two parts. Firstly you will be presented with a sequence made up of symbols, numbers or letters which you need to look at and compare to the second sentence, which can contain up to four mistakes, and you need to indicate how many errors are present on the next screen.

Speed and accuracy are measured here so it is important to assess the sequences quickly and make the correct decision.

How is the British Army error detection test scored?

The ACT error detection test is scored in relation to the rest of the assessment, and is based on the number of correct answers and the time taken to answer the questions.

The score for the ACT is presented as the recruit's General Trainability Index (GTI) and needs a score of at least 26 to pass. The score that you get will determine what roles you are most suited for, and in general terms the higher the score, the more roles will become available for you.

To get the best chance of achieving the standard needed for the role you are most interested in, a score of 60 is usually the highest needed, so great performance at every level is necessary to ensure success.

How to pass the British Army error detection test

One of the most important things you can do to ensure success with the ACT and the error detection section in particular is to practice. There is a Practice Test available that will demonstrate the type of questions you will face as well as the format these questions will take.

As the error detection test is about measuring potential, rather than knowledge, you can hone your abilities by practicing elsewhere too - even simple exercises like 'spot the difference' will help you ace the test and perform well.

Before the assessment centre, be sure to be mentally and physically prepared - try and ensure you get a good night's sleep and eat and drink well so that you are ready to concentrate and perform at your best.

As the ACT is completed as part of the assessment centre, there will be a number of other tests to be taken such as a medical and fit test. The best thing to do when you have an assessment centre date already booked is to make sure you are prepared and know what to expect through the day. Your Candidate Support Manager will provide all the information you need to know before you attend, and they are the best person to ask if you have any questions about any specific part of the process.
