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 skill value statistics and the history of skill changes for each performer.

To increase the performer's motivation, make the skill public and set dynamic pricing in the pool.
