Invite Grading Assessors

Send the credentials

Once you have your photos, participants’ IDs, and your question ready, you can invite the assessors to begin the study by sending them their credentials.

The photo comparison can be carried out on either a smartphone or a laptop.

If there are too many photos to grade at once, assessors can stop at any time and come back to the study later.

Assessor’s point of view

Here’s what the process looks like for an assessor:

1. The personal link redirects the assessor to a page where they type in their PIN.

2. They see a short explanation of what the photo comparison study is about and click “Begin”.

3. They start comparing the photos!

4. In case of a misclick, there is always an option to go back by clicking on the “Back” button in the bottom-left corner of the screen.

5. The assessors can see how many stages they have left in the bottom-right corner of the screen.
