Narrative:

I was training a developmental on arrival radar. Aircraft X inbound to lwv; a satellite airport just outside of our airspace that we sometimes work approaches into. Aircraft was descended to 030 and they requested direct the final approach fix for the RNAV 9 approach to set up for the visual. Developmental first gave the wrong fix to the wrong approach and cleared the aircraft for the RNAV 18. After pilots second request they were given direct the final approach fix. When the aircraft was observed crossing the fix and turning toward the airport the developmental advised them to report the airport in sight; to which they replied they were established on the approach and would call the airport in sight. I questioned the developmental on the pilot advising they were established on an approach they were not cleared for. Our radar coverage is not good in that area and we lost the track on the aircraft occasionally; but on the next good hit the aircraft was observed at about 020; when the last assigned altitude was 030. I told the developmental about the altitude discrepancy and at about that time the aircraft reported the airport in sight and cancelled IFR. There was confusion on both sides with the aircraft proceeding to the final approach fix; advising they were established on an approach they were not cleared for; spotty radar coverage and the developmental not knowing what to do. Also with it being a high performance aircraft all of this happened pretty quickly and before proper instructions could be given the aircraft cancelled IFR and was switched to advisory as they were within 2-3 miles of the airport. Immediately question the pilot when they advised they were established on the approach.
