When a candidate writes a story in a TAT, she has to structure it according to the given instructions. A story should have three components – what led to the situation (past), what is going on (present) and what the outcome will be (future).
What the picture usually shows is the present which is a consequence of something which happened before. So, the candidate has to give a background to the problem briefly. Then, she needs to show actions by the hero to tackle the problem presented in the picture. The bulk of the story should contain actions.
After performing the actions, the story must have an outcome which shows that the hero has achieved her goal. The candidate should structure all the stories in this way.
