# How do I specify the train/validation/test splits?

> Suggest Edits

In some scenarios, you may want to specify your train/validation/test splits. For example, you may need to enforce additional constraints required by your organization, like ensuring that there is a sufficiently large gap between the training dataset and the holdout dataset.

Kumo’s model planner allows you to easily control your data split strategy. You can specify a custom split method and parameter to generate a training, validation, and holdout set by setting the split value in the `Model Plan` box.
