Narrative:

Aircraft X declared a near midair collision with aircraft Y after aircraft Y went through the final approach course for the parallel runway. Aircraft Y was told to maintain visual separation with aircraft X and they acknowledged. Several factors played a role during this event. I believe time on position and having the position combined played a role. Also; I had trained for approximately 3.5 hours and had 3 different trainers in that time span. However; aircraft Y was given a heading approximately 1.5 NM from the final approach course and cleared for a visual approach. If the aircraft turned in a timely manner; this would not have been a factor. Sectors should be split as much as possible. Also; training with the same trainer during the entire session should be done to the maximum extent possible.
