# HumanEvaluationConfig
<a name="API_HumanEvaluationConfig"></a>

Specifies the custom metrics, how tasks will be rated, the flow definition ARN, and your custom prompt datasets. Model evaluation jobs use human workers *only* support the use of custom prompt datasets. To learn more about custom prompt datasets and the required format, see [Custom prompt datasets](https://docs.aws.amazon.com/bedrock/latest/userguide/model-evaluation-prompt-datasets-custom.html).

When you create custom metrics in `HumanEvaluationCustomMetric` you must specify the metric's `name`. The list of `names` specified in the `HumanEvaluationCustomMetric` array, must match the `metricNames` array of strings specified in `EvaluationDatasetMetricConfig`. For example, if in the `HumanEvaluationCustomMetric` array your specified the names `"accuracy", "toxicity", "readability"` as custom metrics *then* the `metricNames` array would need to look like the following `["accuracy", "toxicity", "readability"]` in `EvaluationDatasetMetricConfig`.
