Narrative:
While conducting training; aircraft X was given a heading to avoid VFR traffic. When the traffic was out of the way; the developmental advised aircraft X; that 'traffic was no longer a factor; he is climbing through 11000; proceed direct XXXX.' the pilot of aircraft X read back; '11000; direct XXXX; traffic in sight.' while discussing with the developmental whether or not that read back was good; it appeared that aircraft X was climbing. I instructed the developmental to verify the altitude of aircraft X. The developmental asked aircraft X to verify that he was level at 10000. The pilot said he thought we wanted him to climb to 11000. Aircraft X was instructed to descend and maintain 10000. The pilot was never assigned any altitude; and even in his read back never stated the word climb. The pilots should be required to use prescribed phraseology just as controllers are required to do.
