 ## Understand evaluation flows
 
-A prompt flow is a sequence of nodes that process input and generate output. Evaluation flows consume required inputs and produce corresponding outputs that are usually scores or metrics. Evaluation flows differ from standard flows in their authoring experience and usage.

 The outputs of the evaluation flow are results that measure the performance of the flow being tested. Evaluation flows can have an aggregation node that calculates the overall performance of the flow being tested over the test dataset.
