The results of the TST determine which technical roles are available to prospective soldiers; as a fail in the TST would not preclude an individual’s ability to pursue a career in the British Army in another non-technical role.
The TST is essentially a maths test, with the questions being similar to those one would encounter in any standard GCSE text book.
The TST was introduced in June 1995 to measure the mathematical capability of applicants to the Army’s technical corps.
Various validation studies have been conducted since that time resulting in the cut-off scores shown below for those trades that require a TST level to be achieved, with the highest score achievable being 55 points.
Four new versions of the TST were developed, validated and introduced in 2009 to allow for test rotation in the Assessment Centres, and to increase security.
Who Takes the Test?
Those candidates eligible for consideration for a technical trade will be required to take the British Army’s Technical Selection Test (TST) at the Army Development and Selection Centre (ADSC) in order to confirm their suitability for technical training.
Candidates hoping to go into technical trades, in any of their 3 job choices, within the following will be required to complete the TST:
- The Corps of Royal Engineers (RE);
- The Royal Corps of Signals (RCS);T
- The Royal Electrical and Mechanical Engineers (REME); or
- The Royal Logistic Corps (RLC) as an Ammunition Technician.
TST or BARB Test
The TST is completed in addition to the BARB Test.
Outline of the TST
The TST comprises 28 types of question across 55 multi-choice questions, which must be completed in 45 minutes. The use of a calculator is permitted, which is provided. The name and number of questions of each type making up the 55 is shown in brackets after the name of each type of question:
- Whole Number Division (2)
- Decimal Addition (1)
- Decimal Subtraction (1)
- Decimal Multiplication (2)
- Decimal Division (2)
- Fraction Addition (1)
- Fraction Subtraction (1)
- Fraction Multiplication (2)
- Fraction Division (2)
- Fraction Conversion (2)
- Metric Unit Conversion (2)
- Averages (2)
- Ratios (2)
- Proportion/Scale (2)
- Percentages (2)
- Arithmetic Progression (2)
- Standard Form (2)
- Significant Figures (2)
- Volume (1)
- Simultaneous Equations (3)
- Factorisation (3)
- Area (2)
- Angles (2)
- Transposition (1)
- Graphical Interpretation (2)
- Prefixes (2)
- Indices (4)
- Precedence (2)
These questions test an individual’s maths and are similar to those one would find in a GCSE text book.
TST Scores by Trade
The scores range from 0 to 55, depending on the number of correct answers. The threshold score for a role varies between the different roles. Candidates should try to get the highest score they can to confirm their suitability for the role they want. The specific trades requiring candidates to undertake the TST and the minimum score requirement tor each is shown in the following table.
- JE = junior entry (under 17.5 years old)
- SE = senior entry (over 17.5 years old)

|RE||Command Control & Systems Engineer (JE/SE)||16|
|REME||Vehicle Mechanic JE/SE||16|

For those candidates who fail the TST, and are recommended by their Army Development and Selection Officer (ADSO), there is only one re-sit allowed with a minimum period of 28 days between tests. Test results are valid for 24 months from the date of the pass.
Should candidates want to improve their score, they may take just one re-test with a minimum of 28 days between tests. The test scores are, again, valid for 24 months from the date of passing the TST.
