What necessary step follows receiving instruction after failing a practical test?

After failing a practical test, the necessary step is to acquire an endorsement from the instructor who provided the training. This endorsement is crucial because it signifies that the instructor has assessed the student's progress and believes they are ready to attempt the test again. The instructor typically provides the necessary instruction and feedback on the areas that need improvement, ensuring that the student has adequately addressed the deficiencies noted during the practical test.

This endorsement serves as a formal acknowledgment of the student's readiness and can also be required by the testing authority to demonstrate that the student has completed the necessary training to attempt the practical test again. Having an instructor's endorsement is, therefore, a key part of the retraining process and is aligned with the standards set by aviation regulatory authorities.

In contrast, simply waiting a month or logging additional flight hours without this structured training and evaluation does not guarantee that the student has adequately prepared for retesting. Similarly, retaking a written examination is not typically required unless specified, as the focus here is primarily on practical skills development and readiness.
