Are there any tests required to become a student pilot?

No. To obtain a student pilot certificate you must pass the medical exam discussed earlier. (Before the first solo, you must pass a written exam administered by your flight instructor (14 CFR section 61.87). To obtain a higher certificate you must pass a knowledge and practical test. The knowledge test is administered by computer and is good for a period of two years. The practical test examines your flying skills and ability against a published standard during an examination flight with a Designated Pilot Examiner (DPE) in the category and class of aircraft in which you are getting your pilot certificate. Part of the practical test is an oral examination administered by the DPE.
