Narrative:

I was training a low time developmental on local south. My developmental asked local north for a release on air carrier Y on the skips departure. The local north controller advised my developmental that he/she was released to follow a mnate departure B737 off of runway 8R. At the appropriate time; my developmental cleared air carrier Y for take off on runway 9 to fly runway heading and to expect a turn southbound when airborne in order to guarantee separation with the crossing B737 mnate departure. After air carrier Y was airborne; the local north controller asked my developmental if air carrier Y was going to be on a 120 heading to which he/she replied; affirmative. At the same time the developmental transmitted to air carrier Y to turn right heading 120 and contact departure. Air carrier Y did not reply to the transmission. At that point; I noticed that the local north controller had departed air carrier X on a 105 heading converging with air carrier Y at the same altitude. I advised the local north controller that air carrier Y had not acknowledged his turn to 120 and that I did not have contact with him. I attempted to contact air carrier Y several times in quick succession; but received no reply. I then tried to contact the 'west' south departure controller to see if he was talking to air carrier Y; but heard him turning the aircraft to avoid air carrier X. The local north controller approached me at this point and apologized for his mistake. Separation was lost; and the conflict alert had already been activated. Recommendation; I am sure this will sound trite and contrived; but after numerous incidents related to low time developmentals being trained; I feel that it may be advised for the FAA to quit sending 'no time' developmentals to high level ATC facilities. In spite of trainers genuine and determined efforts to teach these zero knowledge developmentals how to work complex and difficult traffic situations; it is apparent that these types of situations continually present themselves; and are beyond the trainers ability to prevent.

Title: MIA Controller providing OJT described a loss of separation event when the developmental was slow to act decisively; the reporter noting the assignment of minimal experienced controllers to busy/complex facilities was ill advised.

Narrative: I was training a low time Developmental on Local South. My Developmental asked Local North for a release on Air Carrier Y on the SKIPS departure. The Local North Controller advised my Developmental that he/she was released to follow a MNATE departure B737 off of Runway 8R. At the appropriate time; my Developmental cleared Air Carrier Y for take off on Runway 9 to fly runway heading and to expect a turn southbound when airborne in order to guarantee separation with the crossing B737 MNATE departure. After Air Carrier Y was airborne; the Local North Controller asked my Developmental if Air Carrier Y was going to be on a 120 heading to which he/she replied; affirmative. At the same time the Developmental transmitted to Air Carrier Y to turn right heading 120 and contact Departure. Air Carrier Y did not reply to the transmission. At that point; I noticed that the Local North Controller had departed Air Carrier X on a 105 heading converging with Air Carrier Y at the same altitude. I advised the Local North Controller that Air Carrier Y had not acknowledged his turn to 120 and that I did not have contact with him. I attempted to contact Air Carrier Y several times in quick succession; but received no reply. I then tried to contact the 'W' South Departure Controller to see if he was talking to Air Carrier Y; but heard him turning the aircraft to avoid Air Carrier X. The Local North Controller approached me at this point and apologized for his mistake. Separation was lost; and the conflict alert had already been activated. Recommendation; I am sure this will sound trite and contrived; but after numerous incidents related to low time developmentals being trained; I feel that it may be advised for the FAA to quit sending 'no time' developmentals to high level ATC facilities.
