# Validate the Training

After training has been completed, you'll want to go back over your images and ensure that the tool correctly identified the characters in the images. Again, you can use the Database Overview window to review the table of characters, and review the results. Each character the tool found should be the expected character; for example, for the #2, all of the instances in the Display window should be of the #2. If there are instances where there is a "5" or an "S", for instance, you will need to click on that image and re-label those instances with the correct label.

If the tool found all of the instances correctly, the tool is ready for runtime deployment. However, if you had to re-label some of the instances, you will need to retrain the tool, and then repeat the validation process.
