# Testing your classifier

> Test a classifier with the Benchmark tool in FlexiLayout Studio: split a batch into training and test documents and analyze classification statistics.

A classifier's quality depends on the size of the training batch. For classifier training, we recommend using all available images in a batch.

However, this makes it impossible to evaluate the quality of a classifier outside of its training documents. The **Benchmark** tool was created for classifier testing. It lets you split the documents into training and test documents using a percentage ratio.

This tool is used only for unbiased evaluations of the classifier quality. To create the classifier itself, all available images should be used during training.

To split the batch into test and training documents, go to the **Batch** menu and open the **Split Batch** window. Select the appropriate ratio for splitting the source batch (60%-40% by default). Specify the minimum number of documents of each class in the resulting new batches. By default, each batch should have at least 1 document of each class. Specify names for the batches and click **Split**.

To use batches created with **Split** for training and testing, select the **Batches** window in the **Batch** menu. Select **Benchmark**. In the drop-down list, specify the batch that will be used for training. Use check marks to specify the batches that will be used for testing a trained classifier.

Clicking **Run** will launch the training, after which classification will immediately start.

Click **Statistics** in the **Batches** window for an analysis of the test batch classification results.
