You can use skills to restrict access to a pool. A skill is an assessment of some aspect of the user's performance (a number between 0 and 100), which can be updated as tasks are completed.

To select users by skill:

  1. Create a skill.

  2. Set up a quality control rule for calculating the skill.

    You can also set and edit the skill value manually.

  3. Add a skill filter to the pool.

You can track statistics for skill values and the history of skill changes for each user.
