    How to select performers
    Note. The list may take several minutes to load. If you see Users not found, try to wait a bit or use filters.
    If you know the performer IDs

    To select one performer, enter their ID in the search field and click Search.

    To select multiple performers:
    Tip. To view detailed information about a performer, click on their ID.
    Show blocked users
    By default, blocked users aren't displayed. Click the drop-down list for other options:
    Exclude those who haven't used Toloka for a long time.
    Choose Show active users and specify the number of days when the user completed at least one task.
    Find those who opened or completed my tasks

    In the left part of the window use the Project and Pool fields to select performers who opened tasks in one of your projects or pools.

    On the pool statistics page, these performers are listed in the Interested in pool field.

    The Completed field shows the number of completed tasks. If the number is 0, it means the user only opened a task but didn't complete it.

    Find performers with a skill

    To find performers by skill, use filters:

    Filters for selecting performers work the same way as in the pool. Learn more in the Filters section.

  3. Hover over the skill line and click .

  4. Open the downloaded file and choose a pipe | as a separator. The file may contain the following fields:

    • worker_id — Performer ID.
    • pool_id — ID of the pool where the skill is used as a filter or in a quality control rule. If the value is empty, it means that the skill was assigned to the performer manually.
    • skill_id — Skill ID.
    • skill_name — Skill name.
    • value — Skill value.
    • created_date — Date the skill was created.
    • action — Action: CREATE/MODIFY.
    • message — Message.

    The file contains the skill change history for the last three months.

To view statistics about use of a skill, select it on the Skills page.


Should I create a skill for every pool?

It is better to use one skill in a project. You can choose the way to calculate the skill:

  • Calculate the skill for each pool separately. The current skill value is the value of the skill in the pool the user completed last. This option is convenient if:

    • The pools are intended for different groups of performers (for example, there are filters by city or country).

    • Pools are started one by one and you don't want to take into account the responses in the previous pools to calculate the skill in the current pool.

    This calculation method is used by default when adding a quality control rule to a pool. For the control tasks block, leave the Recent values to use field empty.

  • Calculate skill based on all tasks in a project This option is good if the pools are small and you don't need to have skill calculated for each pool.

    This option is available only for skills on control tasks. To use it, fill in the Recent values to use field in quality control rules in pools.

Can I use a skill beyond a particular pool or project and apply it to other projects as well?

Yes, of course — you can use the same skill for different projects. But most often, a skill is intended for a specific project. If the performer completes a certain task well, this doesn't mean that they will complete other ones successfully. Another disadvantage is that if you filter by skills that were set long ago, you will artificially limit the number of available performers.

More than 500 performers passed the training, but the training skill shows only 30.

The pool shows the total number of performers that completed at least one assignment. A training skill can be lost over time if you set repeated training in the pool settings. This setting allows a performer to pass the training again after a certain period if the performer didn't complete any tasks in associated pools or if there was a large time gap between completing tasks (for example, because of the ban). The training skill displays the performers who either recently completed training, or regularly complete your tasks so that the skill doesn't expire.
