# Using the skill

You can use skills to filter and select Tolokers when assigning tasks, issuing rewards, and sending out messages.

When setting up a pool, you can use skills in filters to:

• Select Tolokers without a skill. To do this, use the =, and leave the value empty.
• Select Tolokers with any skill value. Use the ≠ operator, and leave the value empty.
• Select Tolokers who have a skill value greater than or less than the specified one.

For example, you can select only those Tolokers whose skill is more than 66 or is missing:

For global skills, the restrictions of the skill >80type are used to select “Tolokers who completed similar projects 80% better on average than other Tolokers”.

## Extra rewards

To select Tolokers by skill and give them rewards:

1. Go to the Tolokers page.

2. Select Tolokers using the skill filter. To do this, use filters:

2. Scroll down and choose Choose skill.

3. Specify the skill and the required skill value.

3. To credit rewards to one Toloker, click the link to their ID in the Toloker ID field.

On the page that opens, click Actions → Issue bonus.

To credit rewards to a group of Tolokers click Issue bonus.

4. Fill in the fields in the Issue bonus window that appears:

• Bonus per user in dollars.

• Topic and Message for Tolokers. Specify the projects and accomplishments the reward was granted for. To send messages in different languages, use the button for switching languages.

5. Click Grant.

Before doing this, check the number of people who will receive the reward, and the total amount.

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 Toloker completed last. This option is convenient if:

• The pools are intended for different groups of Tolokers (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 control task responses 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 control task responses to use field in pool quality control rules.

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 Toloker 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 Tolokers.

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

The pool shows the total number of Tolokers 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 Toloker to pass the training again after a certain period if the Toloker 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 Tolokers who either recently completed training, or regularly complete your tasks so that the skill doesn't expire.
