Command Terms

In the IB psychology course, there are two types of command terms.  First, there are the command terms that may be used for short-answer questions (SAQs).  These are limited to describe, explain and outline.  These command terms test your knowledge and ability to apply theories and concepts.

Secondly, there are the command terms that may be used for extended response questions (ERQs) - what most people refer to as essays.  These are limited to: contrast, discuss, evaluate and to what extent.  These command terms assess your ability to think critically and to synthesize the big ideas of psychology.

It is essential to master the meaning of the command terms so that you don't just provide memorized information on the exam, but actually address the demands of the question.  This section of the text will look at the role of command terms in assessment.
