Narrative:

The pilot does not have the aviation english communications skills to operate in the national airspace system. This pilot was unable to communicate and read back basic ATC instructions. He caused radio frequency congestion; did not understand basic instructions. When he departed; I instructed the pilot to turn his transponder to the on position. I did not receive an acceptable reply. He was instructed to turn to heading 110 and contact departure. I did not receive an acceptable reply. He did not contact the departure controller and left our airspace with his transponder in the off position. This is the second week in a row that we have had a solo student whose basic english skills are unacceptable for operation in the NAS. They are probably out of the same flight school. Recommend FSDO iniate an investigation into where this aircraft is based and follow up with a on site visit to the flight school. The instructor(s) that are allowing these individuals to fly in the NAS should receive some special attention. These pilots are causing havoc and high workload and are unsafe.
