# Exception Report

{% hint style="danger" %}
The Exception report can only be used for exercises with **preregistered participants (ie. uploaded to the Team table) using the Email registration** type (the data is based on the uploaded teams list).
{% endhint %}

The Exception report provides you with information about participants who haven't started the exercise yet. This is determined by whether participants have interacted with the first step yet, which is usually the "welcome" data point in a LISA-generated quiz. 

| Report    | Description                                                                          | Use when                                                                     |

| Exception | A list of participants that **haven't reached the first data point** of the exercise | You want to see **which/how many participants haven't started the exercise** |

The generated spreadsheet shows you which participants didn't get to the first data point. This means these participants didn't start the exercise.
