About CEB's Diagrammatic Test

The name Diagrammatic Test is associated with many different cognitive assessments. Across the assessment industry, each test publisher makes a slightly different use of that word and even within CEB's SHL line of products, the word diagram is mentioned in four different contexts! In the following article, we will explain the differences between each type of diagrammatic test and refer you to relevant practice resources developed by our test team. The good news is that JobTestPrep can help you prepare for each of these four tests.

Diagramming (DIT5)

This test is used mostly in the selection of IT staff. According to CEB's SHL, this test: "Measures logical analysis through the ability to follow complex instructions....candidates must follow a set of instructions, defined in the form of coded symbols, to manipulate a series of figures."

The test measures a candidate's ability to handle multiple and inter-dependent commands.

  • Duration: 20 minutes
  • Number of questions: 50

Diagrammatic Reasoning (DIT6)

According to SHL, this test: "Assesses the ability to infer a set of rules from a flow chart and to apply these rules to new situations. This test is a high level measure of symbolic reasoning ability and is especially relevant in jobs that require the capacity to work through complex problems in a systematic and analytical manner, for example, in systems analysis and programme design".

This test is quite similar in nature to the DIT6 mentioned above, as you are still required to analyse a process and how parts of it affect its progress. However, the representation of the process is slightly different. An image example is available in the top image gallery (4th image).

  • Duration: 35 minutes
  • Number of questions: 40

Diagrammatic Thinking (DTS6)

According to SHL, this test: "Assesses the ability to follow a sequence of interdependent symbols arranged in a logical order. This ability to apply checks and follow sequences is likely to be relevant in tracking process control systems, debugging software and in systems design."

In short, it is very similar to the above diagrammatic tests. The last image in the above gallery could give you a better understanding of the test's nature.

  • Duration: 20 minutes
  • Number of questions: 36

Diagrammatic Series

This test is also known as Inductive Reasoning or Abstract Reasoning. This is probably the most popular non verbal reasoning test used these days by all assessment companies, in particular CEB's SHL. The test presents series of shapes (3-7) that follow a certain logic, e.g. increase in shape size, decrease in number of sides, etc. The candidate needs to choose the next shape in each series. 

  • Duration: 20 minutes
  • Number of questions: 40 

This test's format is covered in our SHL-Style Logical/Inductive Reasoning practice pack
