# Considerations for Evaluation Flows for Flow Approval Processes

An evaluation flow is an autolaunched flow with a process type of Evaluation Flow that contains a predefined Boolean output variable. Use evaluation flows to define complex entry or exit conditions in flow approval processes. Before you use an evaluation flow, review the general guidelines and how to manage the predefined output variable.

## General Guidelines

Use an evaluation flow when you can't clearly define your entry or exit criteria with 10 requirements.

In evaluation flows, don’t loop through records or make external callouts.

To pass variables from the flow approval process associated with an approval submission into an evaluation flow, use evaluation flow input variables.

## Output Variable

An evaluation flow has one output variable named isOrchestrationConditionMet.

The isOrchestrationConditionMet output variable must be Boolean and initialized to `false`.

The values of all output variables other than isOrchestrationConditionMet are discarded and aren't used by the flow approval process.
