When you start a new project, you'll be prompted to go through an onboarding course to help familiarize yourself with the project instructions. Courses teach you the rules you’ll follow when labeling a project. Course have two components: Instructions and Practice Scenarios.

Instructions
Instructions should describe what the project is, the workflow for the task, as well as details about each label. Reading the instructions will help you understand how to label correctly and with high quality. If the instructions are unclear, please share feedback with your project manager.

Training Tasks
Training tasks are practice tasks that help you learn what good quality labels look like for the project. After instructions, you might see training tasks if your project manager created them. You can practice labeling these tasks with no consequences – they won’t be submitted as part of the completed data, and you can attempt training tasks as many times as you’d like until you get them correct.
