Internet Reasoning Test

IRT3 is an item banked assessment that has been designed to assess general reasoning ability and is available for unsupervised administration via Psytech GeneSys. Suitable for non-graduate level applicants, it consists of three sections which can be administered individually or together, measuring Verbal, Numerical and Abstract reasoning ability.


Report Options

These online report options are available for the following assessment

What IRT3 measures

Verbal Reasoning measures basic vocabulary, verbal fluency and the ability to reason using words. This test is appropriate for all jobs which require a general level of verbal ability (e.g. junior sales and administrative positions, clerical jobs).

Numerical Reasoning measures the ability to use numbers in a logical, efficient way. This test is appropriate for all jobs which require a general level of numerical ability (e.g. accounts clerks and technical roles).

Abstract Reasoning measures the ability to understand abstract logical problems and use new information outside the range of previous experience. This is the purest form of mental ability and is least affected by previous education and achievement. It is therefore ideally suited to assess individuals of various educational backgrounds and cultural groups.

Item Banked

IRT3 is an Item Banked assessment of general ability and can therefore be administered using remote unsupervised administration via Psytech GeneSys.


IRT3 provides a comprehensive assessment of mental ability. It is quick to complete, taking 14 minutes plus administration time. As mental ability has been consistently found to be the best single predictor of job performance, the IRT3 is an essential tool for cost-effective selection and assessment across a wide range of roles. It is available in Psytech GeneSys Online only either as a supervised or unsupervised assessment.

IRT3 Reports

Decision-maker and candidate feedback reports are available for IRT3. They present a detailed breakdown of the respondent’s performance across the sub-scales using profile charts and narrative. The group report option provides decision-makers with a summary of the results from a number of respondents ranked according to performance.
