Effective and economical, the IST-Screening test is particularly suitable for use with large numbers of applicants early in the selection process. Designed specifically for use in the early stages of selection, the test consists of three sections which quickly and effectively screen for aptitude in three distinct areas – verbal (Analogies), numerical (Number Sequences), and non-verbal (Matrices). The overall score assesses logical reasoning ability and provides a sound basis for deciding which applicants should progress to the next stage of the process. Now with new UK working population norms, IST-Screening is also available in German and Italian, and a newly developed French adaptation will be published later this year.


To access tests on our HTS 5 platform

Users can choose from either a subscription or a non-subscription option. With the subscription model, users will pay an annual fee (now half price!) – which then allows them access to a full range of discounted pricing, based on the quantities of test takers they have. Those opting not to use the subscription model will pay our regular prices which include our full-service administration fee.

Good news! To support our customers during the Covid-19 pandemic, we are waiving the HTS 5 subscription fee from 1st April 2020 until further notice. Customers can therefore benefit from an account on our state of the art HTS 5 testing platform and access tests at our ‘with subscription’ rates. Contact us by phone on +44 (0)1865 797920 or email to discuss getting started with HTS 5. You can find out more about HTS 5 here.

Product Description

What are the benefits of the IST-Screening test?

  • IST-Screening allows unsuitable applicants to be screened out early in the selection process, reducing recruitment overheads without compromising quality.
  • IST-Screening saves time and money, effectively evaluating verbal, numerical and non-verbal aptitude in less than 30 minutes.
  • Unlike similar tests, IST-Screening gives a total score across all three areas of aptitude, allowing an overall assessment of applicants.
  • Online administration is quick and easy via Hogrefe Testsystem 5 (HTS 5), while online scoring guarantees accuracy and removes the need for manual scoring.

How does the IST-Screening test work?

IST-Screening comprises three subtests designed to assess aptitude in three distinct dimensions – verbal (Analogies), numerical (Number Sequences) and non-verbal (Matrices). The test taker is given a combined total score (logical reasoning) across all three areas:

  • Analogies are an indicator of verbal intelligence. This subtest assesses abilities in the handling of linguistic material in the context of logical reasoning. It involves both mastery of vocabulary and the ability to identify relationships between concepts.
  • Number Sequences are an indicator of numerical intelligence. This subtest assesses arithmetical skill and the ability to identify logical relationships between numbers.
  • Matrices are an indicator of non-verbal intelligence. This subtest assesses the handling of figural and pictorial material. It involves, among other things, the ability to identify logical relationships between figures.

These three different elements involve both inductive and deductive reasoning, resulting in a total score for all three tests which indicates the test taker’s logical reasoning capacity. As the total score comprises verbal, numerical and figural components in equal proportions, the assessment gives a broader picture of general aptitude than would be obtained by focusing on just one or two elements.
